## About Retell AI
Retell AI is a powerful conversational AI platform designed to automate voice, SMS, and chat interactions with natural, humanlike performance. Built on top of your choice of large language models (LLMs), Retell allows teams to spin up real-time AI agents that handle calls, trigger messaging workflows, and integrate seamlessly into your existing systems—all without writing code. At its core, Retell delivers Voice Agent Automation that feels indistinguishable from speaking with a real person. Calls are handled by LLM-native agents that respond within 600 milliseconds, support multi-turn logic, and operate across 31+ languages with native-quality speech. You can build and manage your own agent flows using an intuitive drag-and-drop builder that supports IVR trees, dynamic transfers, real-time webhooks, and CRM integration. Whether you’re scheduling appointments, answering FAQs, or qualifying leads, these agents are fast, reliable, and production-ready. Beyond voice, Retell also enables SMS and chat automation. Agents can send contextual messages during or after phone calls, or operate as standalone text/chat bots. You can use Twilio numbers or bring your own for outbound campaigns, enabling flexible, multi-channel engagement. To ensure quality and insight, Retell offers built-in testing and QA tools. You can simulate conversations, A/B test call flows, and monitor live call data through detailed dashboards. Track CSAT, latency, sentiment, and conversation outcomes—all in one place. Voice agents can be deployed via Twilio, SIP, branded caller ID, or embedded using Retell’s web SDKs. Unlike legacy IVR or scripted systems, Retell is built from the ground up to be AI-native and fully customizable. Whether you’re in healthcare, logistics, fintech, or customer support, Retell’s platform lets you scale personalized conversations across channels—boosting customer satisfaction and reducing operational costs.

## Retell AI Reviews
  ### 1. The ultimate tool for AI voice assistants

**Rating:** 5.0/5.0 stars

**Reviewed by:** Sebastian  M. | Director IT, Small-Business (50 or fewer emp.)

**Reviewed Date:** August 13, 2025

**What do you like best about Retell AI?**

Retell AI has completely transformed the way we manage automated calls, with impressive voice quality and understanding.

**What do you dislike about Retell AI?**

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.

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

Retell AI has allowed us to automate service and sales calls that previously required a large amount of staff, reducing costs and response times. Now we can serve customers 24/7, with a level of personalization and naturalness that enhances the user experience and increases the conversion rate. Additionally, the integration with our internal tools allows us to connect real-time data, streamline processes, and obtain precise metrics to optimize each interaction.

  ### 2. Great product easy to implement

**Rating:** 4.5/5.0 stars

**Reviewed by:** Stuart M. | Sales Manager, Small-Business (50 or fewer emp.)

**Reviewed Date:** May 15, 2026

**What do you like best about Retell AI?**

Very simple to setup and very easy to manage everything

**What do you dislike about Retell AI?**

I get a bit confused about how nodes work it would have been a lot easier if they have provided very rich documentation around every nodes and how can we use them to the fullest potential.

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

It helps me filter out leads

  ### 3. Really effective and easy-to-use voice AI

**Rating:** 5.0/5.0 stars

**Reviewed by:** Jonathan M. | Founder, Small-Business (50 or fewer emp.)

**Reviewed Date:** August 13, 2025

**What do you like best about Retell AI?**

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.

**What do you dislike about Retell AI?**

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.

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

It allowed me to run a voice-based survey for a Business Chambers client - moving their (boring) survey from web to voice saw deeper engagement and answers.
Several clients are interested in using it to qualify leads. But the UK's GDPR and other regulations mean you need already active consent to receive 'automated calls' from every prospect to use AI voice calls

**What do you dislike about Retell AI?**

It would be great if RETELL can have a client end dashboard(can be white-labelled) like other provide, all-in-one. now i have to use 3rd party dashboard wrapper as client end dashboard. i suggest RETELL should have a function where we can generate quick demo call, for example, if i am with a client, i can simply put client's website into knowledge based, based on the info, i can do a quick demo call to secure my sale. now its long to do prompt and show client a demo, especially i white-label RETELL and 3rd party wrapper dashboard to show client the call data on 3rd party wrapper dashboard.
