1. Grammarly, best known for sentence formatting 

You probably recognize Grammarly from its years as an app for improving your written content. As an AI writing assistant, it provides comprehensive grammar, punctuation, and clarity feedback to ensure your content avoids errors and conveys its message. Grammarly also checks for plagiarism and adapts suggestions to your writing style and tone. 

The AI assistance -- the green light bulb plugin you may have noticed with Grammarly extensions is a generative AI feature that surpasses grammar checks, offering content suggestions and generation to help you write with clarity and impact. 

Victoria and I like how Grammarly offers quick checks for grammar errors, such as misspellings, sentence run-ons, or subject-verb.

Are you curious to know what G2 users think of Grammarly? Read our take on whether Grammarly Premium is worth it.

What users like best:

“Our entire company uses Grammarly, a fantastic tool that not only helps in catching spelling and grammatical errors, but also provides suggestions on how to improve writing. The new AI writing tool is super valuable as it easily summarizes text, gives suggestions on how to expand on a topic, and re-words things that may not be clear. Personally, I plan to use Grammarly for life because it has been such a great help.”

- Grammarly Review, Eric F.

What users dislike:

“I would like the ability to add specific jargon and other words to my personal Grammarly dictionary. For example, the word "proof" has an alternate meaning – according to Merriam Webster: ‘a copy (as of typeset text) made for examination or correction.’ However, Grammarly doesn't recognize this meaning and flags it every time. There are a few other words I use regularly (and correctly) that Grammarly always flags, and it doesn't seem like I can do anything to stop this.”

- Grammarly Review, Tim S.

2. Notion, best known for text-based content generation 

Notion’s all-in-one workspace offers a flexible system for organizing projects, tasks, and data. Its built-in AI content writer puts advanced writing features directly within your notes and documents, so you don’t have to bounce between Notion and your work. This integration unclogs your workflow and keeps you focused on creating important content.

What stood out to us was that Notion's AI content generator helps find and format citations for works mentioned in your writing document. 

What users like best:

“I love the AI writing assistants! They have been a huge help in redesigning my portfolio and rewriting my resume. Being able to draft out what I want to say and then using the AI writing assistant to clean up my grammar and writing has been game-changing. Another huge plus is how easy they are to use and the ability to quickly iterate on an idea.”

- Notion Review, Michael S.

What users dislike:

“While a selling point of Notion is its powerful tools, the complexity is also a downside. It took me several tries to understand it, and I gave up just as many times until it finally clicked. Notion does a decent job of helping you learn, but it's almost like trying to teach someone Adobe Photoshop. There are so many tools that you kind of need to dive in and explore in order to learn them all. That itself is a barrier of entry for the person who isn't technically inclined.”

- Notion Review, Jesse K.

3. Jasper, best known for AI content generation

Jasper, a next-generation AI writer that simplifies and elevates your content creation process. By intelligently analyzing your writing style and goals, Jasper makes real-time suggestions and generates a variety of creative text formats, including blog posts, social media captions, and marketing emails. With support for over 30 languages, you can organize projects effortlessly across the globe and collaborate with just about anyone, just about anywhere. This lets you focus on high-level ideas while Jasper handles the heavy lifting of writing and editing.

Victoria and I like how Jasper provides the right guidance for writing compelling work as it simultaneously directs you to ample learning resources and tips for optimal results.

What users like best:

“The best part about Jasper is its extensive library of templates, which significantly simplifies content creation. You can choose a template tailored to specific needs, such as a blog post or LinkedIn post, and Jasper automatically applies preconfigured settings. This user-friendly approach sets Jasper apart from other large language models like ChatGPT.”

- Jasper Review, Nadja H.

What users dislike:

“Jasper can be a bit cookie-cutter if you don't know how to work with it effectively. It can sometimes make the content sound very generic, and sometimes, it has difficulty rewording it another way. Maybe it gets a bit of writer's block too, where it will just repeat what you've said in a different order instead of actually rephrasing it.”

- Jasper Review, Brittani C.

4. Simplified, best known for social media content creation

Simplified commands a comprehensive suite of AI tools within a single platform to create and collaborate content creation efforts. From writing marketing copy to designing visuals and generating high-quality videos, Simplified caters to the diverse needs of creators, marketers, and businesses. Its success is born from its no-code design editor, AI writing assistant, extensive template library, multi-brand management capabilities, and unlimited workspaces. 

Victoria and I appreciate that Simplified’s AI tool condenses long documents or texts into a brief summary.

What users like best:

“The dashboard and user interface are exceptionally user-friendly and visually appealing. I particularly appreciate the look and feel while working with it. The features and suggestions offered are genuinely helpful. Additionally, the text-to-image and video features produce impressive results. Brainstorming blog topics and content creation within Simplified is easy.”

- Simplified Review, Sheeba T.

What users dislike:

“I would like it if there was a menu across the top of the screen allowing easier access back to scheduling posts when you have been working in a different area, i.e., AI writing. I haven't found the social media quotes very effective. After using it once, it was found to be an inaccurate quote. I also wish it would allow tagging within the social media element.

- Simplified Review, Tracey J.

5. Anyword, best known for tailored content

Anyword’s comprehensive AI-powered platform specializes in copy intelligence and generative AI. It helps users create high-volume, brand-aligned content that pushes conversions and sales. Using billions of data points from the marketing landscape, Anyword equips you with predictive performance scoring and insightful analytics for real-time monitoring and optimized generated copy.

What stood out to us was how Anyword lets you make comprehensive editorial calendars that multiple users can access.

What users like best:

“I work in an advertising agency where deadlines are very tight and clients constantly have new orders. Anyword helps my team and I get past the brainstorming phase and create compelling copy in just a few clicks. We've saved a lot of time, especially when writing ads, and the ability to develop our own tone of voice has helped us a lot. Anyword is a valuable tool that I would recommend to any copywriter, marketing team, or agency.”

- Anyword Review, Ren H.

What users dislike:

“The main drawback I've encountered with Anyword is that the generated content often requires editing. While it provides a helpful framework, the output necessitates fact-checking and revision to ensure accuracy.”

- Anyword Review, Eduardo G.

6. Writesonic, best known for form generation

Writesonic is an AI writing platform designed for users of all skill levels. The intuitive user interface, similar to Canva for writing, paves the way for you to create, edit ,and publish a variety of content. Whether you’re working on SEO-optimised articles, blog posts, social media headlines, landing pages, or product descriptions, Writesonic's comprehensive suite helps you accomplish your mission. 

The Writesonic application is available as a plugin to use with another document creation product. We love that!

What users like best:

They are unique and effective, and they help to organize your ideas and focus on the most important points related to your topic. Using these tools can save time and increase productivity without sacrificing the quality of your writing. Give these tools a try and experience the benefits for yourself.”

- Writesonic Review, Tea B.

What users dislike:

“The only suggestion I have is for an additional writing option. For instance, it would be beneficial if Writesonic could extend articles based on user-provided content or ideas. This would allow users to input their draft or starting points and have Writesonic generate additional insights and expand upon the content.”

- Writesonic Review, Zafar A.

7. Constant Contact, best known for speed 

Constant Contact’s powerful AI assistant simplifies and optimizes campaign effectiveness. The user-friendly platform simplifies the process of designing appealing emails, managing subscriber lists, and taking campaign performance to the top. Work with Constant Contact's AI email generator to come up with more engaging subject lines, suggest relevant content based on audience behavior, and learn personalized recommendations to improve open and click-through rates. 

Our favorite aspect has to be Constant Contact’s power to detect plagiarism beyond content generation. 

What users like best:

“The interface is easy to use, and my clients can get a hold of it quickly. The support documentation and their customer team cover everything you need to know. Constant Contact has exceeded expectations to utilize AI and everything to empower users best to achieve engagement goals. The implementation is as easy as logging in and following simple instructions. I use it to send emails, organize contacts, and get reports on a frequent basis. I also integrate it with Wordpress and WooCommerce easily.”

- Constant Contact Review, Alec M.

What users dislike:

“Sometimes the creator can be a bit wonky when it comes to text formatting. I sometimes have to flip back and forth to different styling.”

- Constant Contact Review, Oliver S.

8. Wordtune, best known for grammar checks

Wordtune supports reading and writing. It understands your intent and suggests modifications to enhance clarity, persuasiveness, and authenticity in your writing. Using generative AI, Wordtune offers sentence rephrasing in various tones. It can even craft entirely new sentences or paragraphs tailored to your writing style. 

Beyond being an AI content writer, Wordtune extends its functionality to summarizing lengthy texts. It can condense articles, PDFs, and even YouTube videos into easily digestible summaries.

Victoria and I like how Wordtune allows users to generate copy based on text prompts.

What users like best:

“Incredibly easy to use, Wordtune provides multiple, accurate suggestions for improvement. The seamless plugin integration makes it a valuable daily tool. I rely on it for realistic suggestions on my writing content. Customer support is impressively responsive, and implementation across various platforms is fairly straightforward.”

- Wordtune Review, Amit B.

What users dislike:

“The icon pop-up can be intrusive within Gmail, hindering a smooth workflow. Additionally, occasional glitches occur, including instances where the paragraph option only analyzes sentences. Thankfully, the frequent glitches experienced a few weeks ago appear resolved. However, compared to some competitors who offer discounts, the lack of a non-profit pricing tier is a factor that may prompt me to switch to a different service.”

- Wordtune Review, Miye M. 

9. Apollo.io, best known for generative writing

Apollo.io relies on its cutting-edge AI writing assistant to analyze user intent and writing style and suggest personalized email content and outreach sequences. The AI assistant refines the sales engagement process by generating targeted messaging and improving conversion rates. Apollo.io equips sales teams with the tools and insights needed to identify, connect with, and convert high-value prospects, accelerating the sales cycle and maximizing revenue potential.

Victoria and I like Apollo.io’s speech-to-text feature which transcribes sales calls from speech to text without a hitch.

What users like best:

“Apollo.io is a goldmine for marketers. Find your ideal leads with laser precision using their massive database and advanced filters. Craft targeted campaigns with ease using templates and automation. It's not just leads – track progress and optimize for success.”

- Apollo.io Review, Dheeraj C.

What users dislike:

“As a beginner, I found the user interface could be more user-friendly. New users might struggle to understand it quickly and may abandon the platform if they can't grasp it immediately. A simpler onboarding process, perhaps including a beginner-focused video tutorial from the support team, would greatly improve the user experience.”

- Apollo.io Review, Yashika M.

10. Axios HQ, best known for content personalization

Axios HQ centralizes communication channels with its comprehensive platform to help organizations elevate their internal communications strategy. A key differentiator lies in Axios HQ's innovative AI writing assistant, which makes content creation easier by analyzing communication goals and user preferences. It suggests clear language to make sure messages resonate with the intended audience. The AI assistant also offers content formatting recommendations for optimal readability and impact internal communications that drive employee alignment and success.

What stood out to us is how Axios HQ allows users to embed a variety of content types to their newsletters, including videos, images, and links.

What users like best:

“The AI features pushing you to write in the "Smart Brevity" format are very helpful. The collaboration tools are easy to use and intuitive. We have increased the amount of important information we share with our members and do so in an easy-to-read and understand format.”

- Axios HQ Review, Monika G.

What users dislike:

“I think some additional collaboration tools would be helpful for users who are going through multiple drafts with their content. Also, some of the options (like version history) seem to go away once an email is sent. It would be great, looking back, to see who made a particular change (especially if the change created an issue with the content).”

- Axios HQ Review, David B.
