Retell AI Reviews 816

Awesome - great for my projects its very functional and has variety I need. I like this company very very much!

I am AI Automation and integrations Engineer and i have used many voice AI agents but i most say that retell AI is one of the best when it comes to voice AI assistants because firstly the UI, they provide is very simple yet very complete, literally even a non-technical person can build his own voice AI agent. Secondly the variety they provide, and the quality of voice AI agents enhances the experience of customers. 9.5/10.

One of the best voice agents - it is awesome!

Retell is one of the solutions most used by our agency; it simply propelled us forward in record time.

It's easy to use and work well no need any coding and talk like real human.

Retell is an incredible product - the AI is amazingly accurate and real, the tool is easy-to-use, but most importantly, the team is fantastic -- super supportive and

The accessibility to external api's helped my n8n workflow smooth & fast.

Quality product that is robust and yet affordable to get started!

Best AI system I’ve used so far. I had a company in my industry try to charge me hundreds of dollars for their AI phone system. Turned out they themselves are using Retell AI. I love being able to tweak mistakes and correct it after client feedback. Best in class, will always be a user!

The best quality voices of all the AI voice tools I have tried. Best latency (none) and realism.

This an amazing software to use to make great ai agents!

retell voice agents are awesome i done my voice agent project with the help of retell .Its too good...

I created a Spanish agent in Retell for a restaurant, and it is working very well.

Great company, easy to use and reliable, robust service.

We’ve evaluated and worked with multiple AI voice and call automation platforms, and Retell AI stands out for both its technical depth and practical usability.

The voice quality is natural, latency is low, and the platform offers a high level of control for building real, production-ready voice agents—not just demos. The API-first approach and flexibility around integrations make it especially strong for teams that need customization rather than a one-size-fits-all solution.

What impressed us most is that Retell AI clearly understands real-world call flows: interruptions, transfers, intent handling, and edge cases are handled far better than most competitors. Documentation is solid, and the team has been responsive and knowledgeable when questions come up.

This is not a “plug-and-play toy,” but for organizations that are serious about deploying AI voice at scale, Retell AI is a strong, professional-grade platform.

I'm pretty new to all this tech stuff, but I wanted to try building a voice agent that could answer phone calls for my business. I've only been playing with retell for lesss than a month, and learned everything watching ng YT videos, and honestly, I was worried it would be way too complicated for someone like me.
I'm really happy with how things turned out. The retellai website made it surprisingly easy to set up a voice agent that actually talks to customers when they call. It sounds real. The best part is that it can have real conversations with people and figure out what products they're interested in based on what they say. It actually listens and answers.
During the building of the voice agent there were definitely moments where I got stuck, but I could usually find help or figure it out with a bit of trial and error.
What really impressed me is that within just one month, I went from knowing almost nothing to having a working voice agent that's actually going to help my business. in my testing, it's handling calls, chatting with customers, and suggesting the right products based on their needs.

This is the best modern and crusts
Clear voice communication services !
Impressive ,easy and fully functional

Super recommended.

Retell represents a significant step forward in how myself and many others interact with artificial intelligence, particularly in the areas of communication, automation, and customer engagement. What makes Retell truly groundbreaking is not only its technical sophistication, but its practical usability in real-world contexts.

At its core, Retell bridges the gap between advanced AI voice systems and everyday business needs. Unlike many AI platforms that remain highly technical or difficult to implement, Retell prioritizes accessibility and integration. Its ability to generate natural, responsive, and context-aware conversations demonstrates a high level of maturity in voice AI development. This moves automated communication beyond scripted responses and into genuinely interactive dialog. I love it.
