Retell helps me make money with voice agents! **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer Software **Reviewed Date:** April 09, 2026 **What do you like best about Retell AI?** I love Retell because of the ease of use and the easy connection to Twilio. Also the great selection of voices and control of the agent are a big plus for me. **What do you dislike about Retell AI?** Honestly, nothing yet, it has excelled for anything I need it to do. **What problems is Retell AI solving and how is that benefiting you?** It allows me to offer engaging AI receptionist services to my clients with full booking capabilities.

Powerfull AI voice agent platform with great felixibility **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Hospital & Health Care **Reviewed Date:** March 22, 2026 **What do you like best about Retell AI?** The visual node_based flow builder makes it easy to design complez voice agents. Multilingual support and seamless webhook amd Twilio are extremely powerfull for building real business automation. **What do you dislike about Retell AI?** The dashboard occasionally crashes with client_side errors that require refreshing the browser. Publishing errors sometimes appear without clear explanations of what needs to be fixed. **What problems is Retell AI solving and how is that benefiting you?** Retell AI allows me to build 24/7 multilingual voice assistants for local businesses, automating patient intake calls for dental offices. This eliminates missed calls and reduces staff workload significantly. ### 16. The best building interphase, documentation and multilingual voices **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Retail **Reviewed Date:** February 15, 2026 **What do you like best about Retell AI?** The multilingual capabilities are outstanding—switching seamlessly between English, Spanish, and Portuguese is critical for our international business. The documentation is extremely clear, making it easy to implement complex logic like data extraction. The developer dashboard and post-call analysis tools are intuitive and make connecting downstream webhooks (like n8n) very straightforward. **What do you dislike about Retell AI?** The end-to-end latency can sometimes spike (2-3 seconds) when using real-time function calling during the conversation, which creates awkward pauses. We had to move our data extraction logic to the "Post-Call Analysis" workflow to ensure the voice agent remained snappy and conversational without interruptions. **What problems is Retell AI solving and how is that benefiting you?** cheap receptionist to first contact ### 17. Avid User **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Real Estate **Reviewed Date:** March 09, 2026 **What do you like best about Retell AI?** the simplicity of the UI, easily update and/or modify any TTS. Highly customizable! **What do you dislike about Retell AI?** It would be great if the TTS choices were categorized by the intended use. I needed a strong human-like personality with vocal inflections that can carry on natural conversations. Master prompts do not always give you what you need, but certain TTS models are inherently designed to be a certain way, so you do not need to create that specific master prompt. **What problems is Retell AI solving and how is that benefiting you?** creating more free time in my business by contacting and converting cold leads ### 18. very good **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Information Technology and Services **Reviewed Date:** February 17, 2026 **What do you like best about Retell AI?** What I like most about Retell AI is that it is designed to bring voice agents to production with low latency and real control of the conversation flow, not just for making demos. Retell packages it as a complete platform to build, test, deploy, and monitor telephone agents (inbound and outbound). **What do you dislike about Retell AI?** What I like least about Retell AI is its unpredictable modular pricing and the latency that can reach 800 ms, which is noticeable in real calls and disrupts the natural flow. It is also very developer-oriented, with no real no-code tools or autonomous testing, and there are complaints about slow support and issues with GDPR/UK. **What problems is Retell AI solving and how is that benefiting you?** Retell AI primarily solves scalability and cost issues in call centers by automating phone conversations with AI voice agents that handle high volume 24/7 without human agents. ### 19. The best call system with AI **Rating:** 5.0/5.0 stars **Reviewed by:** Nicolas N. | Small-Business (50 or fewer emp.) **Reviewed Date:** May 23, 2026 **What do you like best about Retell AI?** I was able to connect it to my CRM and I have all the records in it. I also created a simulator to train agents. The bots are so good that they schedule appointments on their own. **What do you dislike about Retell AI?** The cyst, I think if it integrates with something other than Twilio, it would be better. **What problems is Retell AI solving and how is that benefiting you?** The lack of people to make calls ### 20. Streamlines Orders with Ease, Needs Better Integrations **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) **Reviewed Date:** January 11, 2026 **What do you like best about Retell AI?** I really appreciate Retell AI for its efficient intelligence and realism in understanding the training prompt. I also enjoy being able to perform automations similar to n8n directly on Retell AI rather than relying on external platforms. The speed and ease of use of Retell AI make it a great choice, to the point that we switched from vapi to Retell AI for these reasons. Moreover, the setup process is straightforward with documentation that's simple and easy to understand, especially when implementing complex operations. **What do you dislike about Retell AI?** Retell AI should provide integrations like Gmail, Google Sheets, Go High Level, and HubSpot. **What problems is Retell AI solving and how is that benefiting you?** Retell AI simplifies the process of booking orders by automatically booking on calls for all lead types. ### 21. Efficient AI Calling Solution **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Food Production **Reviewed Date:** October 31, 2025 **What do you like best about Retell AI?** 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. **What do you dislike about Retell AI?** 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. **What problems is Retell AI solving and how is that benefiting you?** Retell AI solves the problem of manually making repetitive calls. Instead of spending hours dialing, leaving voicemails, and repeating the same introduction over and over, the AI handles those conversations for me. It allows me to automate initial outreach, qualify leads, and collect key information before I even talk to the customer. This saves me a huge amount of time and lets me focus only on serious prospects who are ready to move forward — increasing productivity and reducing workload. ### 22. Easy to build quality voice agents **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Consulting **Reviewed Date:** March 16, 2026 **What do you like best about Retell AI?** I like how easy it is to set up using natural prompting. There are multiple voices to choose from. Retell AI can also sync with functions to do calendar updates and email notifications, etc. **What do you dislike about Retell AI?** I've gotten stuck trying to set up complex multi-prompt agents but that's more of a function of the complexity of the work rather than any fault of Retell AI **What problems is Retell AI solving and how is that benefiting you?** I like to use it for training salespeople, so they can practice conversations before having them for real with customers. ### 23. Best AI Voice Agent for automated B2B outreach and CRM integration. **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Security and Investigations **Reviewed Date:** March 26, 2026 **What do you like best about Retell AI?** The low latency is impressive. I love how easy it is to integrate with Make.com and HubSpot using dynamic variables for my sales agents. **What do you dislike about Retell AI?** The dashboard UI can be a bit overwhelming for new users at first, and I would like to see more native integrations with European CRM systems. **What problems is Retell AI solving and how is that benefiting you?** Retell AI helps me automate initial B2B outreach and lead qualification for NIS2 compliance. It saves my team hours of manual calling and ensures consistent communication with prospects. ### 24. Great platform - sounds so natural **Rating:** 5.0/5.0 stars **Reviewed by:** Ashish G. | Senior Manager Sales and Business Development, Mid-Market (51-1000 emp.) **Reviewed Date:** October 30, 2025 **What do you like best about Retell AI?** 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. **What do you dislike about Retell AI?** 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. **What problems is Retell AI solving and how is that benefiting you?** What problems is Retell AI solving and how is that benefiting you? Retell AI is helping us handle customer calls at scale without needing to hire and train a large call center team. Before, we were either missing calls or spending way too much on human agents for routine queries. Now, the AI handles initial inquiries, appointment bookings, and common questions 24/7, which means our customers get instant responses even outside business hours. The biggest benefit for me is that I can focus our team on higher-value work instead of repetitive call handling. It's also helped us maintain consistency in how we communicate with customers - the AI follows our scripts perfectly every time, which improves the overall customer experience. Plus, I can track and analyze all conversations to understand what our customers actually need, which informs our marketing and product decisions. ### 25. 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. ### 26. 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 ### 27. 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 ### 28. I am impressed about RETELL's function and quality of call agent. Resources are easy to access. **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Consumer Services **Reviewed Date:** March 06, 2026 **What do you like best about Retell AI?** pricing, resources, easy to use, quality of the agent. **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. **What problems is Retell AI solving and how is that benefiting you?** 24/7 call agent, help my client's productivity ### 29. the most reliable tool **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Facilities Services **Reviewed Date:** May 20, 2026 **What do you like best about Retell AI?** I love RetellAI, it is the most stable and reliable solution for voice AI agents out there, there is no other like it. **What do you dislike about Retell AI?** I don't like the option of not having sub-agents for single prompt. **What problems is Retell AI solving and how is that benefiting you?** customer service 24/7, with this time is saved and the company grows ### 30.

Also involves upsells to having a bottle of champagne waiting at the table, etc. ### 49.
