The transcription quality is impressively accurate, the interface is smooth, and the summaries save real time. You can tell the team actually cares about building something useful — updates keep improving the product in meaningful ways. Easily one of the most practical AI tools I’ve used. Highly recommended.

I always have good experiences with this site, its exactly what i was looking for as far as simplicity and very good results and does exactly what it suppose to do and all my customer love it and always refer someone to me that ask or is told and showed to them and end up also wanting an agent also.

It was amazing, we could customise calling agent's voices, add MCP support, the system prompt everything. It helped us equip the agent with all our company's information and context of what we want to do.

This is really a great platform to build voice agents, honestly #1 tool to build voice agents, there are lots of them in the market but retell is the best!
