Vapi
3.8/5 · 70 reviews“It's a quick way to make Voice AI bots with a lot of integrations possible, the platform is straightforward - can learn the basics in 1 hour of youtube video.”
“The single worst thing about VAPI is the latency! It's not predictable. Sometimes the latency is within 800-1000ms and sometimes it goes upto 4-5s which makes it unreliable.”
“Costwise - it's one of the cheapest platform out there to make a voice AI bot.”
“They could improve the dashboard. It's very difficult. I have to be a developer if I want to understand all the options.”
