"USER FRIENDLY AND PAY AS YOU GO - THE BEST IN THE WORLD"

5/5

What do you like best about Retell AI?

The pay-as-you-go pricing is the biggest win for me. As a

solo founder running an AI receptionist agency in Auckland,

I do not want to be locked into big monthly fees before I

have proven the product to my clients. Retell lets me only

pay for what my agents actually use, which keeps cashflow

predictable and lowers the risk on each new build.

It is also genuinely easy to use. I built my first

multilingual agent (English, Mandarin, Korean) in a single

weekend with no coding background. The customisation is

deep too, voice speed, pause length, different voice

models, custom functions for booking and transferring

calls, and an attached knowledge base. Plenty of

flexibility for the different industries I sell to. Review collected by and hosted on G2.com.

What do you dislike about Retell AI?

Adding pronunciations is painful. I have to enter each word

one at a time, and for businesses with NZ place names,

foreign customer names, or industry jargon, it becomes a

huge time sink. A bulk upload or CSV import would save

hours per agent build.

The other thing is the lack of a public voice example URL.

I cannot link to a live demo of my agent on my website or

in marketing materials without first recording a call

myself, then uploading and hosting the audio. A

Retell-hosted shareable audio link would make showcasing

the product to prospects far easier. Review collected by and hosted on G2.com.

What problems is Retell AI solving and how is that benefiting you?

The problem I am solving for my clients is simple: small

businesses in New Zealand lose money every day because they

cannot answer the phone when they are busy with customers

or after hours. A real human receptionist costs $4,000 to

$5,000 a month in NZ which is out of reach for most small

operators. Voicemail does not cut it either, around 85

percent of callers never leave a message, they just call

the next business on Google.

Retell lets me build a multilingual AI receptionist that

picks up every call 24/7 for a tiny fraction of that cost.

My first client is a car valet business in Auckland and the

AI handles bookings, takes messages, and transfers urgent

calls to the owner. He no longer loses customers to missed

calls during busy detailing days.

For me personally, Retell removes the technical overhead of

building from scratch. I can stand up a new client agent in

48 hours, attach a knowledge base, set up the booking

integration with Cal.com, and connect a Twilio number. The

multilingual support is also a huge win for Auckland where

many small business owners deal with Chinese and Korean

speaking customers daily. Without Retell I would either

need a much bigger dev team or a much longer sales cycle,

neither of which fits a solo founder building from zero. Review collected by and hosted on G2.com.

What do you like best about Retell AI?

The modularity and ease of use. They have inbuilt phone number thing/ Review collected by and hosted on G2.com.

What do you dislike about Retell AI?

Well there are some bugs, when I use it for building agent, the workflow was made and when i clicked a function or smth. all the workflow was gone! also there is no straight line when it comes to the pipelining. it is always a bit moved to off side, as a person who has OCD i didnt like that and it does bug me. Sometimes when i am dragging it as a pan, it directly starts to select rather than moving to change the POV. they should fix it. Review collected by and hosted on G2.com.

"AI Restaurant booking Agent"

5/5

What do you like best about Retell AI?

I like to you can add multiple integration programs and use different AI voices Review collected by and hosted on G2.com.

What do you dislike about Retell AI?

It's a bit hard to find support when you have a question. Review collected by and hosted on G2.com.

What problems is Retell AI solving and how is that benefiting you?

I’ve been working with Retell AI to build a custom AI booking agent for a friend’s restaurant, and the results have been incredible.

The platform's low latency, natural conversational flow, and robust API integration made it incredibly smooth to develop exactly what we needed. We were even able to handle complex logistics like custom seating plans and specific time-slot logic without the agent breaking character or lagging.

My friend is absolutely thrilled with the results. It has streamlined his reservations, saved his staff hours on the phone, and never misses a call. If you are looking to build high-quality, reliable conversational voice agents, Retell AI is the gold standard. Highly recommended! Review collected by and hosted on G2.com.

"Strong Real-Time Conversational AI Solution"

4.5/5

What do you like best about Retell AI?

What I like most about Retell AI is the low-latency conversational performance and how easy it is to build production-ready voice agents. The call quality feels natural, the APIs are developer-friendly, and integrations with LLMs, SIP, and telephony providers are straightforward. It significantly reduces the complexity of building AI phone systems while still allowing deep customization for workflows, prompts, and call handling logic. Review collected by and hosted on G2.com.

What do you dislike about Retell AI?

One downside of Retell AI is that advanced configurations can take time to optimize, especially for complex conversational flows and edge cases. Pricing can also become expensive at scale depending on call volume and model usage. Additionally, some areas of the documentation could be more detailed for troubleshooting and enterprise-level deployment scenarios. Review collected by and hosted on G2.com.

What problems is Retell AI solving and how is that benefiting you?

Retell AI helps automate my business outreach by handling voice agent cold calls without needing a human team. It allows me to scale lead generation and contact more prospects in less time. This reduces manual effort and improves efficiency in sales outreach. It also lowers operational costs while keeping calling available 24/7. Overall, it helps me grow my business faster through automated and consistent cold calling. Review collected by and hosted on G2.com.

"I think is easy and usefull, the UI/UX is so impressive"

5/5

What do you like best about Retell AI?

More settings about voice. I think the voice in an agent would be better. The UI/UX is so impressive. The Integrations with Netelip i think is correct, but not's easy. The Performance is incredible, my client is so happy with taht service. About the pricing i think is the best of Retell AI, i love the model "Pay as go". With module of support and onboarding I think is fast. And about AI i think Retell have the best models in the market. Review collected by and hosted on G2.com.

What do you dislike about Retell AI?

"Sounds human, easy to build with, and gets the job done"

5/5

What do you like best about Retell AI?

The voice quality is the standout — it sounds natural and doesn't immediately tip off callers that they're talking to a bot. The dashboard is clean, setup is straightforward, and building out call flows didn't require a ton of technical overhead. Good foundation for anyone running AI voice workflows Review collected by and hosted on G2.com.

What do you dislike about Retell AI?

Pricing can add up quickly depending on call volume, so it's worth keeping an eye on usage. Would love more built-in analytics to track call performance without needing to piece things together manually. Review collected by and hosted on G2.com.

What problems is Retell AI solving and how is that benefiting you?

We use it to handle inbound calls for small businesses so they never miss a lead. Instead of calls going to voicemail, the AI agent picks up, qualifies the caller, and captures the information we need. It saves time on the front end and makes the business look more professional and responsive Review collected by and hosted on G2.com.

"Very intuitive and easy"

4.5/5

What do you like best about Retell AI?

The ultra-low latency and smoothness of the conversations are impressive — patients don't realize they are talking to an AI agent. The integration with ElevenLabs for voices and compatibility with Telnyx for Swiss local numbers make deployment in a medical office truly viable. The dashboard is clean and real-time call monitoring is a real plus for the agency. Review collected by and hosted on G2.com.

What do you dislike about Retell AI?

The documentation lacks depth on certain edge cases (handling long silences, multiple interruptions). Pricing can become high as call minutes scale. There are some sporadic bugs in detecting end of turn in French — the English language clearly remains a priority in optimizations. Review collected by and hosted on G2.com.

What problems is Retell AI solving and how is that benefiting you?

In our agency, we use Retell AI to automate the management of incoming calls in medical offices. The central problem: medical secretaries are overwhelmed, and patients call up to 30 times before reaching someone. Retell AI allows for 24/7 response, qualifying requests, and collecting patient information before manual confirmation by the secretary. Result: fewer missed calls, better patient experience, and a real time saver for the office. For us as a reseller agency, it's a reliable infrastructure on which we can build value-added offers without managing the telephony complexity ourselves. Review collected by and hosted on G2.com.

"easy to set up and 3rd party integ"

5/5

What do you like best about Retell AI?

Best-in-class low latency (~600ms)

This is the standout feature. Conversations feel shockingly natural — quick responses, excellent interruption handling, and smooth turn-taking. It’s currently one of the most human-like experiences you can get in production voice agents.

Realistic voices + strong interruption handling

Voices (especially when paired with ElevenLabs or similar) sound very natural, and the agent handles people cutting in or talking over it without breaking.

Developer-friendly with great flexibility

You can mix different LLMs, voice providers, and telephony (Twilio, Telnyx, SIP trunking, etc.). The visual flow builder + code nodes gives you both no-code speed and deep customization.

Real-time function calling & integrations

It shines when booking appointments, checking calendars, updating CRMs, or pulling live data during the call.

Transparent pay-as-you-go pricing + generous free tier

$0.07+/min + $10 free credits and 20 free concurrent calls makes it easy to test and scale without big upfront commitments.

Strong for real business use cases (especially dental/medical, support, outbound) Review collected by and hosted on G2.com.

What do you dislike about Retell AI?

Steep learning curve for non-technical users

While it has a visual builder, building truly reliable agents still often needs prompt engineering and some technical knowledge.

Unpredictable total cost at scale

You pay separately for LLM, STT, TTS, telephony, etc. The final per-minute cost can climb higher than expected if you're not careful.

Support can be slow

Many users report that customer support is limited (mostly Discord/community), especially for urgent production issues.

Still requires work for complex flows

It’s not fully “set it and forget it.” You’ll spend time testing and refining to handle edge cases well.

Limited native phone numbers

For international or certain regions, you often need to bring your own carrier (like Twilio). Review collected by and hosted on G2.com.

What problems is Retell AI solving and how is that benefiting you?

Missed or unanswered calls + poor after-hours support

Traditional phone lines and receptionists can't be available 24/7. Many businesses lose leads or frustrate customers with long wait times or voicemails.

High operational costs of call centers / staff

Human agents are expensive ($29–$42/hour including overhead). Repetitive calls (scheduling, reminders, FAQs, status checks) burn out staff and drive high turnover (30–45%).

Rigid, frustrating IVR systems

Old phone menus feel robotic and force callers through frustrating button-pressing. They can't handle natural conversation or interruptions.

Slow or impossible scaling

Handling high call volume requires hiring, training, and managing more people. Peaks (e.g., evenings or Mondays) create bottlenecks.

Lack of real-time integration with tools

Manually updating calendars, CRMs, or records during/after calls is time-consuming and error-prone.

Inconsistent or low-quality customer experience

Wait times, tired agents, and human errors lead to lower satisfaction. Review collected by and hosted on G2.com.

"A sneakpeak into the future of the world - How RetellAI is bringing the future to today"

5/5

What do you like best about Retell AI?

I love how there are not many companies that allow users to do what Retell does. By this, I mean I have used the tool so much that I can literally create a functional AI Voice Agent/ Receptionist for anyone or any business in as little as 30 minutes. Review collected by and hosted on G2.com.

What do you dislike about Retell AI?

I understand you're still refining things on your end, but the phone number verification process was a bit confusing and long. As a small business owner, I understand that it takes time for processes to be refined, so this was nothing big enough to deter me from using RetellAI.

Still, I also want to state that I have already created phone numbers (and will soon create separate accounts) for about 5 of our clients, with more on the way soon, and it would be nice to know that the phone number verification process is quicker now than it was earlier this year. Review collected by and hosted on G2.com.

What problems is Retell AI solving and how is that benefiting you?

It is solving the need to have a call center or front office receptionist for starters. It is also cool to have a knowledge base that you can train an agent on, and then speak to that agent, as you would with any other person, to retrieve the exact information you are looking for when you need it.

"So Human like it's awesome!"

5/5

What do you like best about Retell AI?

How realistic the conversation's are, the voices are truely great. I useed SignalWire, and Trilio, and Retell is the best as far as I am concerned! The Support team is 24/7 and are equally amazing. Highly recommend and I don't recommend many products. I don't have time, and most aren't worth a review. I never heard of Retell, but I am glad I stumbled upon them and now I'll help promote them to anyone looking for a truely human voice agent. Review collected by and hosted on G2.com.

What do you dislike about Retell AI?

Nothing, great product! Once you get your agent dialed in, it works amazing! could use more Voices? But I found the ones that work for my business, with the selection they have. Too many and you spend days looking for a perfect voice. I think I like the less is more, I know it's faster and easier the way you have it now. Review collected by and hosted on G2.com.
