Leo AI Speeds Up Engineering Work with Fast, Relevant Knowledge Access **Rating:** 4.5/5.0 stars **Reviewed by:** Eitan H. | CEO, Small-Business (50 or fewer emp.) **Reviewed Date:** March 15, 2026 **What do you like best about Leo?** What I like most about Leo AI is that it helps turn a lot of slow, manual engineering work into a much faster and more efficient process. It is especially valuable when engineers need quick access to relevant knowledge without digging through endless files or relying on memory. The product feels purpose-built for technical teams, and that makes a big difference in how useful it is day to day. **What do you dislike about Leo?** The main downside is that once you start using it, you want even broader coverage across more engineering use cases and workflows. But that also reflects the value it already brings and the potential ahead. **What problems is Leo solving and how is that benefiting you?** Leo helps solve a major problem for engineering teams: too much critical knowledge is scattered across old designs, documents, standards, and people’s heads, which makes work slower, more repetitive, and more error-prone. For us, the benefit is that engineers can find relevant information much faster, reuse existing knowledge more effectively, and spend less time on manual searching and repeated checks. It helps the team move faster, make better-informed decisions, and focus more on actual engineering work instead of chasing information. ### 2. Engineering-Accurate AI with Citations, CAD Awareness, and Traceable Math **Rating:** 5.0/5.0 stars **Reviewed by:** Dorian G. | AI Engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** March 12, 2026 **What do you like best about Leo?** Engineering-Specific Accuracy: Unlike general AI, Leo uses a Large Mechanical Model (LMM) trained on 1M+ technical sources (standards, textbooks, datasheets). It also provides citations, so we don’t have to guess whether a material property or tolerance is correct. CAD & PDM Awareness: It understands your actual geometry. You can search your company’s internal library in natural language, or find standard vendor parts based on engineering intent rather than relying on part numbers. Traceable Math: It handles complex mechanical calculations (stress, thermal, fluid) and often shares the Python-based logic behind the result, which makes it easier to verify and include in technical reports. Efficiency Gains: It consistently saves a lot of time by automating repetitive documentation, part hunting, and early concept generation. **What do you dislike about Leo?** High Enterprise Cost: While there is a professional tier, the most powerful features like direct PLM/PDM integration (Windchill, Teamcenter) and private company-wide knowledge are expensive and mostly geared toward larger firms. **What problems is Leo solving and how is that benefiting you?** Manual data retrieval vs. faster onboarding, with zero time wasted “hunting” for files. Calculation errors vs. higher accuracy, including 96% accuracy on technical queries. Slow iterations vs. generative 2D-to-3D concepting, saving time on early-stage modeling. Vendor part fatigue vs. instant selection of bearings and fasteners that meet specs from our parts and vendor parts. ### 3. Leo AI Saves Engineers Time with Workflow-Smart Guidance **Rating:** 5.0/5.0 stars **Reviewed by:** Elad H. | CEO, Small-Business (50 or fewer emp.) **Reviewed Date:** March 11, 2026 **What do you like best about Leo?** What I like best about Leo AI is how much time it saves our team on work that used to be unnecessarily manual and fragmented. Instead of digging through old files, internal knowledge, and technical sources, engineers can get relevant guidance much faster. It is also clear that Leo was built with a real understanding of engineering workflows, which makes the product feel much more useful than a general AI tool. **What do you dislike about Leo?** As with any ambitious product, there is still room to deepen certain capabilities and make parts of the workflow even more seamless. But what gives confidence is seeing how quickly the platform improves and how closely the team listens to users. **What problems is Leo solving and how is that benefiting you?** Leo AI solves the challenge of engineering knowledge being scattered across too many places and too much valuable time being spent on manual research, repeated checks, and work that has already been done before. In many engineering environments, answers are buried in past designs, internal documents, standards, and team knowledge, which slows everything down. For us, the benefit is that engineers can get to the right information much faster and spend more of their time actually designing and solving problems. It helps improve efficiency, reduces unnecessary repetition, and makes it easier to build on existing knowledge instead of starting from scratch each time. Overall, it helps us move faster and work in a more consistent and informed way. ### 4. Leo AI Dramatically Speeds Up Part Search with Fast Catalog and Geometric CAD Matching **Rating:** 5.0/5.0 stars **Reviewed by:** erga k. | im a product engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** March 11, 2026 **What do you like best about Leo?** I've been using Leo AI for about six months now and it's cut down my part search time dramatically. Before, I'd spend half a day hunting through supplier catalogs and our PLM system trying to find an existing component that met specs. Now I just describe what I need and Leo pulls relevant parts from its catalog in minutes. The geometric search is particularly useful when I have a CAD model and need to find something similar we've already qualified. very easy to implement and integrate especially considering its connecting to a PLM system (windchill) which usually takes months to implement **What do you dislike about Leo?** its quite expensive for a private guy like me **What problems is Leo solving and how is that benefiting you?** so the part search capabilities are really in a league of their own - text to text, text to cad and cad to cad, its really something you have to try for yourself to see. they have really good chat with high accuracy that always gives me the context for the answer and sources, better than perplexity in my opinion and connected to my data. overall a very powerfull tool that saves a lot of time and really cuts down on effort and frustration from these types of common tasks. ### 5. Studio Manager & Industrial Designer **Rating:** 5.0/5.0 stars **Reviewed by:** Harel O. | Lecturer , Small-Business (50 or fewer emp.) **Reviewed Date:** August 26, 2025 **What do you like best about Leo?** As an industrial designer without an in-house engineer, Leo feels like having an expert always by my side. It lets me ask engineering questions, check ideas, and move forward with confidence instead of getting stuck. It bridges the gap between design and engineering, which makes my work much smoother and faster. **What do you dislike about Leo?** Previous Response: The concept development and design side of Leo is not fully developed yet. It still has room to grow when it comes to supporting more creative, early-stage design work. But it’s clearly moving in the right direction, and I can already see the potential. **What problems is Leo solving and how is that benefiting you?** Leo helps me as an industrial designer without an in-house engineer by giving quick, reliable engineering insights. With its component libraries, I can build my design files much faster, saving time in concept development and moving forward with more confidence. ### 6. Instant Access to Cited Internal Knowledge for Confident Design Decisions **Rating:** 5.0/5.0 stars **Reviewed by:** Yuval F. | Doctor, Enterprise (> 1000 emp.) **Reviewed Date:** March 15, 2026 **What do you like best about Leo?** My background is clinical. I understand mechanical design well enough to contribute, but I am not a senior mechanical engineer and I know it. When I joined the device development team at Clalit, one of my biggest frustrations was how much institutional knowledge was effectively invisible. Documents from previous product lines existed somewhere, but finding the right one for the decision in front of you was a project in itself. Leo changed that completely. I describe what I need, and it surfaces the relevant internal material, previous design decisions, past calculations, and backs everything with a cited source I can actually click on and verify. For someone at my level of mechanical experience, having that kind of depth available instantly is the difference between a confident decision and a guess **What do you dislike about Leo?** Getting the integration set up with our internal document repositories took a bit of coordination with IT. It was handled smoothly by the Leo team, but worth knowing it requires that initial step. **What problems is Leo solving and how is that benefiting you?** a large healthcare organization like Clalit, the engineering knowledge from previous medical device programs is enormous but scattered. The people who built earlier products carry a lot of that in their heads, and there is no efficient way for someone newer to access it. Leo indexes all of it and makes it searchable in plain language. Beyond that, for regulatory documentation, Leo was able to help us produce FDA and ISO 13485-aligned drafts significantly faster than doing it manually, and every claim in those documents was traceable to a verified source. For a medical device context where traceability is not optional, that matters enormously. ### 7. Leo AI frees engineers to focus on design work **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Mechanical or Industrial Engineering | Small-Business (50 or fewer emp.) **Reviewed Date:** March 11, 2026 **What do you like best about Leo?** The parts search across our PDM system has been a game changer — engineers find components much faster instead of pinging each other constantly. It integrates seamlessly with our existing PLM setup, so it's not another orphaned tool. The technical Q&A feature pulls from real engineering standards with source citations, giving engineers confidence they're getting accurate, relevant answers. It has noticeably cut weekly meeting load and reduced the number of "can you find X spec" emails significantly. The ROI is clear when you consider how much time senior engineers were spending on retrieval tasks. **What do you dislike about Leo?** Nothing major to report so far. The initial setup and integration required some coordination, but once it was connected to our PLM system it has been smooth. Would love to see even broader coverage of engineering standards over time. **What problems is Leo solving and how is that benefiting you?** Leo is solving the problem of engineers spending too much time on retrieval tasks — searching for parts, looking up specs, and tracking down information across disconnected systems. Before Leo, senior engineers were frequently interrupted to help with these searches, which cut into actual design work. Now the team can find components through the PDM system quickly and get reliable answers to technical questions independently. This has freed up senior engineers for higher-value work and reduced unnecessary meetings and emails. ### 8. Engineering AI that Boosts Part Search and Reuse **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Consulting | Small-Business (50 or fewer emp.) **Reviewed Date:** March 11, 2026 **What do you like best about Leo?** It is especially useful because of the parts search and the fact that answers are backed by trusted sources instead of unverified web content. The result was less search time, better reuse, and faster decisions. That is what made it stick. I would recommend Leo AI to teams that are tired of wasting time looking for answers they already have. **What do you dislike about Leo?** Some integrations are still not available for certain systems. Mobile web version still has limited functions, but I assume it will improve overtime. **What problems is Leo solving and how is that benefiting you?** It cut down the dependency on waiting for the right person to be free before moving forward. Leo AI feels like real parts search, not a generic tool pretending to understand engineering. The fact that it can be integrated directly into CAD editors or work independently in the web it's also a plus in flexibility. It's also useful that it gave us visible calculation logic with Python code instead of a black box number that came who knows from where and without any backed sources. ### 9. A Game-Changer for Mechanical Engineers **Rating:** 5.0/5.0 stars **Reviewed by:** Max B. | Small-Business (50 or fewer emp.) **Reviewed Date:** March 11, 2026 **What do you like best about Leo?** I really appreciate Leo's ease of use; it makes me feel like I'm using a product from the future. It's pretty cool to see something that's on the cutting edge for mechanical engineers. I find it incredibly useful as it's a classic chatbot that condenses information well. Instead of looking things up on Google, it's much easier to find what I'm looking for, like parts or fasteners, or a good solution for my specific problem. Also, the initial setup was very easy. **What do you dislike about Leo?** I think there's a little bit of issues with stability still to pretty new product, so I think, that they're still working on it. But the team there is, really responsive, so it doesn't make it too bad. **What problems is Leo solving and how is that benefiting you?** I use Leo to find parts for assemblies and for CAD generation, saving me time and reducing costs by using pre-existing parts. It's easy to use, like using the future for mechanical engineering, and it's much easier than searching on Google. ### 10. Revolutionizes Part Search for Engineers **Rating:** 5.0/5.0 stars **Reviewed by:** eytan s. | Mid-Market (51-1000 emp.) **Reviewed Date:** March 11, 2026 **What do you like best about Leo?** As someone working in R&D, I was really impressed by Leo. It's amazing how the part search, or retrieval as they call it, finds parts that I wouldn't have caught otherwise. When we were redesigning a mounting bracket with specific load specs, Leo pulled up three viable options from suppliers I hadn't considered, one of which fit our envelope constraints perfectly. The geometry search has also been invaluable, helping me find standard parts instead of designing new ones, saving a huge amount of time and effort. The search system is smart and CAD-aware, which is a big time saver. I love that it was made by people who truly understand the struggles of mechanical engineers. The connection to our PDM and using that as a data source is legit the best thing ever, and it’s easy to set up with a simple installation process. I also tried the assembly inspection feature, and it looks promising. Overall, this tool has been incredibly useful and is the best thing to have for mechanical engineering tasks. **What do you dislike about Leo?** I guess speed could be improved. **What problems is Leo solving and how is that benefiting you?** Leo AI helps me find parts I wouldn't find otherwise, saving me time and effort. Its smart search system is CAD-aware, delivering better results. It simplifies finding standard parts and connects seamlessly to my PDM, improving my R&D workflow. ### 11. LEO AI from an Engineering Student's Perspective **Rating:** 4.5/5.0 stars **Reviewed by:** Benjamin L. | Student, Small-Business (50 or fewer emp.) **Reviewed Date:** December 01, 2025 **What do you like best about Leo?** What I liked the best about LEO and the most helpful thing about LEO AI is its ability to give you a place to start in design. Instead of worrying about where to start or what to do, LEO AI will give you something to work off of and the information needed to do it. **What do you dislike about Leo?** The main thing I disliked about LEO was what I would call its "stubbornness." Occasionally, the software did not quite listen to what I was saying. It would sometimes design something outside of my prompt or not quite listen to material specifications. This issue mainly occurred when the software was asked to make a 3-D model, but did not occur when asking for specific information about the design in my experience. **What problems is Leo solving and how is that benefiting you?** LEO AI is great for giving you a place to start in terms of design. The design the software comes up with will not always be the final product, but it does give a great place to start from and build off from. The software is also great at answering engineering questions throughout the designing process and generally gives you what information you would want for a project. Something that helped me as a student using LEO was its ability to somewhat teach certain engineering concepts and breaking down larger concepts in a digestible way. ### 12. Leo Gives Our Engineers Fast, Cited Answers from Our Own PLM and Defense Standards **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Defense & Space | Enterprise (> 1000 emp.) **Reviewed Date:** March 13, 2026 **What do you like best about Leo?** The search in Teamcenter has always been a weak point for us. If you don't know the exact part number or file name, you're basically not finding it. Leo changed that. I can describe a part geometrically or by function and it finds relevant parts from our own history, not just from an external catalog. For a team our size with years of legacy NX data, that's a significant time saver. We've started reusing parts we didn't even know we had, and that has real downstream impact on procurement and BOM costs. **What do you dislike about Leo?** Getting Teamcenter fully connected took a bit of coordination with our IT team, but the Leo support team walked us through it and it went smoothly. **What problems is Leo solving and how is that benefiting you?** In a company our size, with years of NX assemblies and program documentation in Teamcenter, the knowledge is there but it's not accessible. Engineers spend a lot of time trying to understand design intent on systems they didn't originally build, especially when the people who built them are no longer around. Leo helps with that directly. It can surface previous design decisions, pull up the right calculation or standard, and help a newer engineer get context fast without having to track down a senior who may or may not have time to explain. On the IP and security side, that was a concern when we first evaluated it. Leo is SOC 2 certified and nothing leaves our secured environment, which cleared the procurement review without issues. ### 13. The Next Leap for Mechanical Engineers Since CAD - AI for MechEs **Rating:** 4.5/5.0 stars **Reviewed by:** Uriel B. | Field warfare and survivability specialist, Mid-Market (51-1000 emp.) **Reviewed Date:** September 20, 2025 **What do you like best about Leo?** I work as a mechanical engineer in a large enterprise, and I see Leo as the next leap in our profession since the invention of CAD. It’s the only AI for Mechanical Engineers that actually understands CAD, PLM, and the realities of enterprise design work. With Leo, our team improves design quality, reduces mistakes, and shortens time-to-market. Instead of wasting hours on repetitive searches and calculations, we focus on making better products and leading our category. For enterprise teams, this is the AI for Mechanical Engineering we’ve been waiting for. **What do you dislike about Leo?** Leo is still evolving, even though very rapidly, and sometimes it takes a few extra seconds to process bigger requests. The integration setup with our PLM also needed IT support at the beginning. Not deal-breakers, but worth mentioning. **What problems is Leo solving and how is that benefiting you?** Accurate calculation of mechanical problems, including sources and mathematical formulas, and methods for solving the problem. ### 14. AI Copilot for Mechanical Engineers: Faster, Confident Design of Our Next-Gen GPU Cooling **Rating:** 5.0/5.0 stars **Reviewed by:** Adi R. | R&D PMO, Mid-Market (51-1000 emp.) **Reviewed Date:** September 07, 2025 **What do you like best about Leo?** In our group, we’re building heat transfer systems for GPUs using principles that are so new, there’s barely any precedent in the industry. That used to mean hours digging through journals, standards, and textbooks- often paying for articles and experts/consultants just to get the data we needed to test a single idea or to make a single decision (material properties, relevant standard, etc). With Leo, that’s changed completely. When I explore a new cooling geometry or evaluate unconventional material properties, I can ask questions and get answers backed by handbooks, standards, and recent studies. The best part is that the sources are included in our Enterprise tier, so we dont need to pay to get those sources- they are already included with the Leo Enterprise Tier. This is an immidiate ROI and we get access to the relevant literature we need. the service the Leo Team provides is incredible- they are always there for us for any questions, making sure we get the best out of Leo and solve issues super fast. They are available for our engineers arrounf the clock It gives me the confidence to move faster on designs that push the limits of what’s been done before. I know the data is credible because every recommendation is cited, whether it’s from a trusted standard or an academic paper. For us, that means less guesswork, fewer delays, and more time focusing on innovation in GPU cooling. Leo isn’t just speeding things up - it’s raising the quality of our decision-making. For mechanical engineers working on bleeding-edge problems, that combination is a game changer. **What do you dislike about Leo?** There’s nothing I dislike, but I’m excited about the upcoming features, particularly the Onshape integration. **What problems is Leo solving and how is that benefiting you?** Instead of hours searching through journals and textbooks, you get quick answers Saves money on purchasing articles and consultants - sources are included in Enterprise Tier Answers backed by handbooks, standards, and recent studies Every recommendation comes with citations to credible sources Leo team available around the clock for your engineers Fast issue resolution and optimization guidance Less guesswork, fewer delays Greater confidence in pushing design boundaries More time to focus on innovation rather than information hunting ### 15. Leo Makes Assembly Reviews Smarter with Intelligent Part Recommendations **Rating:** 5.0/5.0 stars **Reviewed by:** Ricardo I. | mechanical engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** January 28, 2026 **What do you like best about Leo?** What I like most about Leo is its ability to review assemblies and provide intelligent part recommendations. It can search within our own library, helping engineers reuse existing components, reduce design time, and improve consistency across projects. **What do you dislike about Leo?** What I dislike is that Leo does not yet fully analyze complete assemblies. I would like it to automatically detect interferences, design flaws, and potential failures, and then provide clear, actionable recommendations on how to resolve each issue efficiently safely. **What problems is Leo solving and how is that benefiting you?** Leo helps solve design review and component selection challenges in water treatment projects. It speeds up assembly reviews, improves part reuse, and reduces engineering time, helping us deliver systems like filters and pumping skids faster and with fewer design errors. ### 16. Huge time saver - will become the gold standard rapidly **Rating:** 5.0/5.0 stars **Reviewed by:** John H. | Global Board of Directors, Small-Business (50 or fewer emp.) **Reviewed Date:** September 05, 2025 **What do you like best about Leo?** Every mechanical engineer I know hates wasting days modeling parts that already exist in the company library. Leo fixes that problem completely. By combining enterprise-grade AI with organizational CAD and text data, it allows engineers to find and reuse the right part or standard instantly. One director told me their new hires used to take months before they could work independently. With Leo acting as an AI copilot, those same engineers are productive in weeks. Add SOC 2 security and local support in the US and EU (Germany, Switzerland, France, Belgium, Netherlands, Luxembourg, Poland, UK, etc) that provide technical support both in person or virtually in various native languages , and it’s clear this is the enterprise tool mechanical engineering organizations have been waiting for. **What do you dislike about Leo?** Nothing so far ... all users with whom I have spoken love it. **What problems is Leo solving and how is that benefiting you?** The most important benefits are reducing time wasted seeking the right parts and helping new hires get up to speed quickly. ### 17. A first hand experience of what AI can do for mechanical engineers **Rating:** 5.0/5.0 stars **Reviewed by:** Arumuga N. | Chief Executive Officer, Mid-Market (51-1000 emp.) **Reviewed Date:** September 04, 2025 **What do you like best about Leo?** It makes ideation much faster, and the ability to bring tonnes of engineering handbook data at the fingertips is of great help. **What do you dislike about Leo?** Nothing I dislike about Leo. Like other AI tools some times it hallucinates but we can easily correct it with appropriate prompts **What problems is Leo solving and how is that benefiting you?** LeoAI is the AI tool mechanical engineers have been waiting for is my first impression after seeing the demo. I tried my hands on it with certain use cases and the way it brought out the best data points, made me convinced and hooked. I have shared it all around. As of today, LeoAI is the only trusted AI tool available for mechanical engineers. While other tools give some information, the confidence with which you can use the results is very small compared to LeoAI. The best part is it connects to the customers design data, PLM system, understands CAD and has inherent ability of having put the best practices in place. Like, if I need a part, say ball bearing, Leo pulls the relevant formulas and guidelines from my organisation's data, trusted engineering handbooks, showing exactly where the formula came from. This increases the trust on the results. Then it runs the calculations with Python code and gives the results. And it finds the right one from standard part catalogues as well. Leo enables the engineers to focus on progress, and it takes care of the mundane and tedious tasks behind daily decisions to be made. In summary Leo has become a center of almost every discussion between engineers I work with, my customers and prospects. It is the AI that I was looking for taking to the large community of mechanical engineers. ### 18. Leo is my go-to AI for my work. **Rating:** 5.0/5.0 stars **Reviewed by:** gal s. | mechanical engineer, Enterprise (> 1000 emp.) **Reviewed Date:** September 03, 2025 **What do you like best about Leo?** It saved me a lot of time anytime I have technical questions associated with mechanical engineering and product design, enhances my creative process, and prevents potential errors before they occur. For example, Leo was very accurate about the surface roughness of both answers while referring to our specific use cases - something that Google cannot do. Leo was accurate and quantitative about the thickness and homogeneity of both coatings (thickness in each of them in microns). He also provided supporting sources that allowed me to be confident with my decision and explain it to my peers. That was great. **What do you dislike about Leo?** Nothing, I have no complaints and no dislikes. **What problems is Leo solving and how is that benefiting you?** With LEO, I’m able to retrieve data very quickly, sometimes even information that I would otherwise need to search for in catalogs. When it comes to calculations, once a request is made, LEO clearly shows the process — including parameters and the resulting output. For consultation or in cases of uncertainty, LEO provides an answer along with references that can be verified. ### 19.

It really boosts my productivity. For example, when I had to build a machine for my company, it helped me do it 10 times faster. The initial setup was also really easy, taking one day at most. **What do you dislike about Leo?** The UI sometimes isn’t that intuitive. **What problems is Leo solving and how is that benefiting you?** Leo solves the search problem for building blocks in my machine, making it 10 times faster. It's convenient, quick, accurate, and enhances my productivity. ### 20. Efficiency and error reduction at its best! **Rating:** 5.0/5.0 stars **Reviewed by:** Michal G. | Advisor, Small-Business (50 or fewer emp.) **Reviewed Date:** September 05, 2025 **What do you like best about Leo?** Leo is the first AI product I’ve seen that truly understands the realities of mechanical engineering inside large organizations. By connecting directly to PLM and leveraging both CAD files and internal documents, it standardizes decision-making across the team. Instead of every engineer reinventing the wheel, Leo brings organizational memory to the surface instantly. We’ve seen engineers reduce design mistakes in critical assemblies by pulling proven calculations and design rules from past projects in seconds. For a team lead or director, the impact is immediate - fewer errors, faster onboarding of new engineers, and a clear competitive advantage. **What do you dislike about Leo?** Nothing - they are constantly improving. **What problems is Leo solving and how is that benefiting you?** Leo reduces errors and the need for mechanical engineers to redo things that have been done and tested in prior projects. It saves time and money! ### 21. Efficient Optimization with Leo **Rating:** 5.0/5.0 stars **Reviewed by:** Yedidya W. | Small-Business (50 or fewer emp.) **Reviewed Date:** March 11, 2026 **What do you like best about Leo?** I use Leo for answering technical questions and calculations, which makes long and tedious research more efficient. The AI integration is great and very helpful. Setting up Leo was quite simple because they have a lot of tools to help, making it easy to do. **What do you dislike about Leo?** nothing so far :) **What problems is Leo solving and how is that benefiting you?** I use Leo for optimizing my work, making long, tedious research more efficient. The AI integration is very helpful. ### 22. Probably the only AI that can search CAD and textual mechanical engineering data **Rating:** 5.0/5.0 stars **Reviewed by:** Sergey G. | Board, Small-Business (50 or fewer emp.) **Reviewed Date:** September 23, 2025 **What do you like best about Leo?** Engineering companies generate huge amounts of CAD and text data, but most of it sits unused. Their current tools (CAD editor, PLM) don't provide any useful search capabilities- very minor ones based on the text of the titles of the parts, which is provides bad fit to the problem in hand (the title of the part doesn't describe when'll the geometry of the parts etc), especially for mechanical engineers. Leo changes that. It integrates directly with PLM and existing workflows, making past designs, standards, and calculations instantly available. The result is fewer errors, faster decision-making, and a more consistent process across teams - all with enterprise-grade security. For organizations looking to modernize mechanical design, Leo is a real step forward. **What do you dislike about Leo?** none, I really like it, it's a great tool to use **What problems is Leo solving and how is that benefiting you?** It integrates directly with PLM and existing workflows, making past designs, standards, and calculations instantly available. The result is fewer errors, faster decision-making, and a more consistent process across teams. ### 23. LEO AI - A Game Changer **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Venture Capital & Private Equity | Small-Business (50 or fewer emp.) **Reviewed Date:** September 11, 2025 **What do you like best about Leo?** What makes Leo stand out in the CAD AI space is not just the speed- it’s the reliability. That’s the only AI Mechanical engineers can really trust. Enterprise engineering teams can’t risk mistakes, and Leo addresses that directly by combining SOC 2-level data security with knowledge from both PLM systems and the world’s most respected engineering references.  Imagine you’re leading a section that designs assemblies with dozens of interdependent parts: traditionally, design reviews would drag on for weeks because each calculation and standard had to be verified. With Leo, those checks are automated and tied to the company’s own approved practices. Directors I’ve spoken with said it completely changed how they manage projects: less time on repetitive verification, more time on real innovation. For mid-cap manufacturers that want a competitive edge, Leo is the AI copilot that makes engineering faster, safer, and smarter. **What do you dislike about Leo?** Nothing. I love everything about the product. **What problems is Leo solving and how is that benefiting you?** less time on repetitive verification among many others ### 24. Accelerating Healthcare Product Development from Concept to Compliance **Rating:** 5.0/5.0 stars **Reviewed by:** Ofir S. | Co-Founder and CPO, Small-Business (50 or fewer emp.) **Reviewed Date:** September 10, 2025 **What do you like best about Leo?** Developing medical devices and healthcare technologies is a balancing act between innovation and compliance. Every idea has to be validated against strict engineering standards, backed by standard, regulatory docs (FDA, HIPAA, CE), and documented in a way that regulators will accept. For small to mid-sized companies, that challenge is multiplied by limited resources and the need to move quickly- time to market is everything but the cost of a mistake is insane.  What’s compelling about AI designed specifically for mechanical engineers is how it handles this reality. Instead of offering generic answers from generic AI tools like Gemini of ChatGPT, it can connect the dots between CAD files (assemblies and parts), PLM records, and technical documents, whether that’s an Excel sheet with calculations, a PDF report, or a design review presentation. The result is clarity in decision-making when it matters most: at the conceptual stage, before costly mistakes are baked into the design. For entrepreneurs in healthcare, this means more than saving time. It’s about reducing risk, improving traceability, and giving teams the ability to explore multiple design options without losing confidence in compliance. In an industry where documentation and reliability carry the same weight as creativity, having an AI copilot tailored for mechanical engineers is the kind of advantage that levels the playing field with much larger competitors. **What do you dislike about Leo?** Excited to see what new features and connectivity options are on the horizon! **What problems is Leo solving and how is that benefiting you?** It can connect the dots between CAD files (assemblies and parts), PLM records, and technical documents, whether that’s an Excel sheet with calculations, a PDF report, or a design review presentation. ### 25. Leo Is the GPT for Engineering **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Mechanical or Industrial Engineering | Small-Business (50 or fewer emp.) **Reviewed Date:** September 09, 2025 **What do you like best about Leo?** In the defense industry, engineering teams deal with some of the most complex products in the world- large assemblies, thousands of CAD files, and decades of design documents. The real challenge is navigating the massive amount of organizational knowledge stored across PLM, CAD models, Excel docs, PDF and Word files, technical reports, and presentations. This is where Leo changes the game. It’s the first AI I’ve seen that can actually search and answer questions across both CAD files and text-based engineering documents. I tried to use GPT to analyze cad and it failed, because it’s a language model. Leo, on the other hand was built to understand CAD and engineering data. Instead of digging through endless folders or relying on senior engineers to recall where a decision was made years ago, teams get instant, accurate answers tied back to real models, drawings, and approved documentation. **What do you dislike about Leo?** I love it, but I’m looking forward to their Onshape integration! **What problems is Leo solving and how is that benefiting you?** For large organizations, the impact goes beyond speed. Training new engineers, which used to require months of shadowing experienced colleagues, is now dramatically faster. With Leo, they can ask questions in plain language and immediately see the calculations, CAD assemblies, or reports they need- based on the company’s own standards and previous designs. That knowledge transfer, once a bottleneck, is now built into the workflow. In highly regulated, mission-critical industries like defense, consistency and accuracy are non-negotiable. Leo gives enterprises the ability to leverage their entire organizational knowledge base, reduce errors, and make better decisions- faster and with more confidence. For mechanical engineers working at scale, it’s a real step change in how design and engineering get done ### 26. Leo is changing how engineering teams work **Rating:** 5.0/5.0 stars **Reviewed by:** Or'el S. | Mechanical Design Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** September 09, 2025 **What do you like best about Leo?** Engineering in defense is never simple: countless CAD models, layers of PLM data, and information spread across too many systems. Leo turns this complexity into clarity. Instead of searching for files or recreating past work, our team can quickly identify proven designs, confirm standards, and build on solid ground - a real GameChanger. The difference is immediate. New engineers don’t rely solely on others to explain how things were done in the past. They can verify requirements directly, cross-check against trusted sources, and move forward with confidence. Senior engineers, in turn, gain back time by no longer stuck answering repetitive questions, but able to focus on solving new challenges. One project illustrates this well. While designing a barrel for a strike system, Leo provided the relevant material specifications, dimensional tolerances, and safety margins according to applicable standards. It also surfaced associated inspection methods and fatigue considerations. What would have required pulling from multiple documents and references came together in one reliable flow of information. This isn’t just about convenience. For teams working under tight deadlines and high stakes, Leo reduces errors, accelerates development, and ensures decisions are backed by validated knowledge. For us, it has already proven indispensable. As I already wrote, a GameChanger. **What do you dislike about Leo?** One drawback is that Leo is cloud-only. If you’re offline or dealing with a shaky connection, you simply can’t access it. An offline mode would have made it far more flexible. **What problems is Leo solving and how is that benefiting you?** For me, Leo takes away one of the biggest daily frustrations: wasting time searching through old models, standards, and files just to find something we already solved years ago. Now I can pull up the right info in seconds, reuse proven designs, and be confident I’m not missing a critical detail. It saves me from repeating work, lets me focus on real engineering, and gives younger team members a way to move faster without leaning on me for every answer. ### 27. AI for Mechanical Engineers in Large Organizations: Leveraging CAD Models, PLM, and PDFs **Rating:** 5.0/5.0 stars **Reviewed by:** Michal F. | Director, Mid-Market (51-1000 emp.) **Reviewed Date:** September 06, 2025 **What do you like best about Leo?** Mechanical engineers in big organizations know the real challenge isn’t creating new designs—it’s managing the massive amount of CAD and engineering data that already exists. Our PLM holds thousands of models, drawings, and assemblies, and on top of that there are endless Excel spreadsheets, Word documents, PDFs, and presentations from past projects. Finding the right part, calculation, or decision point at the right time used to be nearly impossible. Leo changes this completely. It’s the only AI solution I’ve seen that understands CAD files and can also search across all the engineering knowledge stored in PLM and organizational documents. Instead of starting from scratch or wasting hours chasing old files, Leo brings the most relevant models, calculations, and reports right to you, with clear references. At the conceptual design stage, that makes all the difference. Leo doesn’t just provide one answer-it gives multiple approaches to the problem in hand, backed by real organizational data and trusted engineering sources. That means faster decisions, fewer design mistakes, and the ability to leverage the full value of the company’s knowledge base. For large organizations looking for an AI solution built specifically for mechanical engineering and CAD, Leo is not just another tool-it’s the copilot that turns overwhelming data into better, faster, and more confident engineering. **What do you dislike about Leo?** There’s nothing I didn’t like. Love it.. **What problems is Leo solving and how is that benefiting you?** Leo helps me in various things during my work, but those are the main ones: 1. find quickly answers to engineering questions in a way i can trust (it adds link to the internal or external docs it was based on) and saved me a lot of time (and embaricment) asking my coleagues so many questions 2. helps me reuse the right CAD and engineering knowledge, saving time and reducing design mistakes 3. reduced me hours and hours training the new engineers that joined the team- it minimilaized the onboarding process, and gets them up to speed super fast (they dont need to ask me every littel question- they go to Leo instead, it provides tehm with the asnwer, and it send them to the relevant sources on our org's data) ### 28. Leo Cuts Through the Noise of Enterprise Engineering **Rating:** 5.0/5.0 stars **Reviewed by:** Yossef B. | Manufacturing Process Engineer, Enterprise (> 1000 emp.) **Reviewed Date:** September 06, 2025 **What do you like best about Leo?** Working in a large organization with hundreds of engineers across multiple sites, the biggest challenge is not the lack of knowledge- it’s the overload of it. At the conceptualization stage, when we’re under pressure to bring fresh ideas to the table, Leo became the engineering companion I always wished I had. Instead of staring at a blank CAD screen or flipping through dozens of old project folders, it sparks different directions, gives structured options, and helps me weigh trade-offs with real confidence. For someone like me, who deals with tight deadlines and the constant distractions of a big engineering environment, having an AI copilot that organizes information and supports decision-making is a game changer. It’s especially valuable for engineers who struggle with focus- it cuts through the noise and points directly to relevant design approaches, calculations, and references. What sets Leo apart is that it’s built by and for mechanical engineers. It doesn’t give generic, vague answers like other AI tools- it connects the dots between CAD models, PLM data, organizational documents, and even previous assemblies. You don’t just get an answer- you see where it comes from (when if gives answers to my equations it provides links to sources from documents we created on our organization and also from external articles or engineering books). That kind of traceability is critical when you’re working on enterprise-scale projects with major consequences for quality, safety, and cost. In my experience, there’s no other AI that understands CAD files this way, or that can answer questions directly on engineering models. For enterprises that want their teams to design smarter, faster, and more consistently, Leo is not just an add-on tool—it feels like part of the team **What do you dislike about Leo?** As it is with all AIs, you have to master the wording when talking to it. But it's something we get better and better at with time. **What problems is Leo solving and how is that benefiting you?** As an engineer with ADHD and working in an environment that can't tolerate ADHD paralysis, Leo has been a great help. I'm no longer anxious about my weekly meetings with my boss. I can get to them with new and various ideas and I can really feel the difference in the way my work is appreciated. ### 29. Leo is a great product **Rating:** 5.0/5.0 stars **Reviewed by:** Mark L. | Partner, Small-Business (50 or fewer emp.) **Reviewed Date:** September 05, 2025 **What do you like best about Leo?** Mechanical engineering teams that adopt Leo won't go back. It’s not just about speeding up CAD work, it’s about transforming how organizations use their own knowledge and how they approach technical design. Like when CAD was invented - people didn't just do the same thing they did when they were drafting on paper - they changed the processes dramatically. Leo mines the company’s PLM data (protected and SOC2 certified) and reliable engineering handbooks, GD&T and tolerance tables, books, and academic papers (not unreliable information from social media, like general LLMs provide), so every engineer on the team has instant access to both. We’ve seen design reviews where managers could validate calculations and decisions in minutes because Leo had already tied everything back to trusted sources and past projects. That level of accuracy, combined with enterprise security and world-class support (based in the US and EU in native languages across Europe), makes Leo the choice for organizations that want to lead the AI revolution in mechanical engineering. **What do you dislike about Leo?** At this point, nothing to dislike compared to prior approaches **What problems is Leo solving and how is that benefiting you?** Ideation, calculation, validation ### 30. Finally, a co-pilot for my engineers **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Industrial Automation | Mid-Market (51-1000 emp.) **Reviewed Date:** September 02, 2025 **What do you like best about Leo?** LLMs like GPT and Gemini are excellent for many individual use cases, but some functions cannot live with hallucinations. A single mistake can have real business consequences, or worse life-threatening ones, and we simply cannot rely on a generic AI model trained on open-source, non-engineering-specific data. Leo is an AI tool specifically designed for mechanical engineers. With Leo, we get answers we can trust - every response is linked to credible sources, whether from established engineering standards and textbooks, or our organization’s proprietary data. It’s also the only AI tool capable of interpreting CAD files, saving tons of hours. With Leo, our engineers can avoid wasting time redesigning components that already exist. The implementations and integration with your PLM is very streamlined and the support team is there to help through every step. **What do you dislike about Leo?** Like any AI tool, it's constantly in development and improvement, and the level of capabilities is improving quickly. The Leo team is very open and responsive to feedback. Some engineers don't like the constant change, others thrive with it. **What problems is Leo solving and how is that benefiting you?** Leo is built to support Mechanical Engineers in their day-to-day work not just in ideation but also in the mundane, boring tasks that make up most of their days. It has reduced the amount of back office, research, and integration work substantially and enables our engineers to go back to the actual building and creative thinking. ### 31. Real AI - Local functionality & SOLIDWORKS integration **Rating:** 5.0/5.0 stars **Reviewed by:** Krzysztof B. | Development and Marketing Director, Small-Business (50 or fewer emp.) **Reviewed Date:** September 06, 2025 **What do you like best about Leo?** The interface of the application is very clear, which makes every function easy to find. Everything is straightforward and intuitive. This solution evolves dynamically; the range of features has significantly expanded between April and August 2025. An additional advantage is the ability to integrate with a local database, which is very useful. **What do you dislike about Leo?** I believe the application could generate better quality conceptual models. It also happens that the results vary from each other, which is undesirable. **What problems is Leo solving and how is that benefiting you?** Leo allows for quick searching of components. The biggest advantage is the ability to search my own database. Furthermore, this solution enables me to add components directly to SOLIDWORKS, which significantly speeds up my work. ### 32. Leo AI is an indispensable tool that amplifies my engineering skills. **Rating:** 5.0/5.0 stars **Reviewed by:** JJ S. | CTO, Defense & Space, Small-Business (50 or fewer emp.) **Reviewed Date:** August 25, 2025 **What do you like best about Leo?** The most helpful aspects of Leo AI are its ability to significantly save time and prevent costly mistakes by providing fast, accurate, and verifiable technical information. The transparency of providing solid references for every data point builds trust and allows you to work with confidence, ultimately enhancing your engineering toolkit and making you a more efficient professional. Ultimately that is the primary upside of Leo AI, how it acts as a valuable amplifier for a mechanical engineer's skills. **What do you dislike about Leo?** However, there are a couple of areas for improvement that I hope to see addressed in future updates. I've found that the AI is still not fully integrated into Onshape, which requires some manual back-and-forth. Additionally, synchronizing my local part library into its database can be quite a slow process. Improving these two functions would make an already great product even more seamless to use. **What problems is Leo solving and how is that benefiting you?** Leo eliminates the significant amount of time spent on manual research and complex calculations, it helps avoid costly mistakes by providing instant validation and data retrieval, and addresses the need for trust and transparency by giving solid, verifiable references for technical information. All this saves me time, prevents mistakes and helps me execute with an elevated level of confidence. ### 33. Great AI copilot for mechanical Engineering **Rating:** 5.0/5.0 stars **Reviewed by:** Ashraf S. | New Product Development Consultant Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** September 04, 2025 **What do you like best about Leo?** It is more like our own version of ChatGPT as mechanical enginees. It provides great value in the early stages of product development, especially in the project planning, ideation and documentation. One of the most important features is the citation and references for any claim or answer it provides me. I used Leo AI to perform a full design sprint in one working day, which took me usually around 5 working days before. **What do you dislike about Leo?** From my own experience, I think there's room for improvement in the concept visualization module. It needs a lot of time and iterations to come up with something relevant. Also, I think the user interface could be improved. **What problems is Leo solving and how is that benefiting you?** Usually it saves me considerable time on the early stages of product development cycle. It augments my product development cycle and helps me do it in a more efficient way. ### 34. Leo Does Today for Mechanical Design and Manufacturing What SolidWorks Did in the 1990s **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Financial Services | Mid-Market (51-1000 emp.) **Reviewed Date:** September 11, 2025 **What do you like best about Leo?** Medium and large engineering teams waste time on design errors, searching for old CAD files, and tedious documentation. Leo fixes this by making a company’s CAD and text data usable. Engineers can instantly find and reuse validated parts, reduce repetitive work, and focus on real engineering. The result: fewer mistakes, faster throughput, and more innovation. Like SolidWorks in the 1990s, Leo isn’t just speeding up processes—it’s changing how engineers work. **What do you dislike about Leo?** I have no complaints. Everything runs smoothly. **What problems is Leo solving and how is that benefiting you?** Medium and large engineering teams deal with the same problems every day: design mistakes that slip through, endless searches for old CAD models or specs, and far too much time wasted on the boring documentation work nobody enjoys.
