Retell AI Reviews & Product Details

Everything about Retell AI is good. I find the overall features and functionality to be satisfactory and efficient in my work. There is no specific feature that is unnecessary to single out because the general performance of Retell AI seems to meet my needs. Review collected by and hosted on G2.com.

I am extremely frustrated with Retell AI because of the issue with saving custom function names. Despite my persistent and time-consuming efforts, I have been unable to save the names, which is incredibly irritating. It has severely affected my patience and made progress difficult, especially considering I rely on custom functions for my work with AI agents for clients. This problem is so disruptive that it makes me reconsider recommending the product, as it is a major source of frustration and inefficiency in my workflow. Review collected by and hosted on G2.com.

What I like best about Retell AI is how natural and human-like the voice sounds during calls. The agent responds dynamically, handles interruptions smoothly, and maintains a real conversation — not just a scripted dialogue. The setup is simple, the interface is clean, and I can build call flows without any technical complexity. Review collected by and hosted on G2.com.

What I dislike is that sometimes the AI pauses a bit too long before responding, especially in fast-paced conversations. Also, more customization for voice tone and emotions would make the experience even better. Review collected by and hosted on G2.com.

The platform is incredibly intuitive to use, even for someone without a technical background like me. I was able to set up and deploy AI voice agents without needing to write code or constantly bug our developers. The voice quality is natural and the conversations flow smoothly, which is crucial for our customer interactions. Plus, their documentation is clear and their support team has been responsive whenever I've run into questions. Review collected by and hosted on G2.com.

Sometimes the platform can feel a bit limited when you want to do more complex customizations beyond the standard workflows. There have been occasional latency issues during peak hours that affect call quality. Also, the pricing structure could be more transparent - it's not always clear how costs will scale as usage increases, which makes budgeting a bit tricky. Review collected by and hosted on G2.com.

Retell AI has completely transformed the way we manage automated calls, with impressive voice quality and understanding. Review collected by and hosted on G2.com.

What I like the most is its ability to create natural voice assistants that understand context and respond like a real human. The integration with APIs and external systems is simple and powerful, and the control panel is intuitive, allowing us to implement changes and improvements in minutes. Additionally, the technical support is fast, approachable, and effective, which makes a big difference. Review collected by and hosted on G2.com.

It's very easy to get started and intuitive. It integrates very easily to Bubble.io and Make.com. You can import numbers from Twilio easily. Their documentation is comprehensive, and the tutorial videos they curate are very useful. The voices and call options are extensive - I love being able to create custom functions for use in a call, and that you can refer to these in the call (this is why I moved away from Synthflow - I wasn't able to detect when a function was running). I appreciate the 'Next invoice' amount being shown, and their general transparency with how much things cost. My clients have been very impressed with the voices. Their 'Single Prompt' agent is powerful enough for pretty tricky conversations, and the 'Flow' canvas allows for very deep conversations. Review collected by and hosted on G2.com.

Having a 'Test custom function' in the backend could be useful, so you wouldn't have to make an actual call or test the bot. Otherwise not much. Review collected by and hosted on G2.com.

Retell AI combines ease of use with powerful capabilities. Implementation was straightforward, and the integration with tools like Twilio works flawlessly. We value the large selection of LLMs and voice providers, including high-quality options like ElevenLabs, which give us flexibility to match different use cases. The platform is updated frequently, with new features and improvements that clearly respond to market needs. Customer support is exceptional – quick, knowledgeable, and genuinely committed to helping us succeed. It’s a reliable, scalable solution that we use regularly and trust for our business.

No major downsides. Occasionally, I wish new features came with more example use cases right away, but the team is quick to add helpful resources. Review collected by and hosted on G2.com.

Sofar there is nothing I dislike about Retell Ai. Review collected by and hosted on G2.com.

I appreciate the customizable nature of Retell AI, which allows me to tailor the platform to suit my specific needs. It's incredibly convenient that there's an option to select a phone number and even get a verified phone number, which boosts the legitimacy of my business. The automation capabilities of Retell AI are invaluable to me in developing a call agent. The service ensures that calls are answered and the individuals handling them are knowledgeable, which helps businesses avoid missed opportunities. Additionally, the overall experience of using Retell AI has been excellent, as reflected in my perfect recommendation score of 10 out of 10. It's been a pleasure to use something so efficient, making it easy to recommend to others. Review collected by and hosted on G2.com.

I needed a little guidance in the beginning to understand where all the nuances are and what each section needs to be set up properly. Additionally, I think the software should provide tutorials within the application. I didn't see any tutorials available unless I missed them. Review collected by and hosted on G2.com.

I love the low latency that I get with retell; I like the clarity of the dashboard. I like that it already has some of the tools set up, that I need - better than other similar services in both respects, which I was using before (not naming names). Review collected by and hosted on G2.com.

It does kind of have its own weird logic that you have to get used to using at first; once you've got that sorted out tho it's all good. Review collected by and hosted on G2.com.

I started using Retell early on and have used it for customer support, sales and a few other roles. I've been so impressed with how they interact with us users, see what needs we have and then build the features or integrations to make it flow even better. The office hours alone have been invaluable. Seriously one of the scrappiest teams out there. Keep it up! Review collected by and hosted on G2.com.

It can be technical at times but for what we're doing and innovating as early adopters we have to push through things like that. Review collected by and hosted on G2.com.
