What it is
Overview
Vapi addresses the challenge of scaling customer interactions for enterprises that need to handle high volumes of phone calls while maintaining service quality. Before Vapi, companies relied on human agents or basic IVR systems that couldn't provide personalized, intelligent responses at scale. The platform targets Fortune 100 companies and enterprises that need to process thousands or millions of calls monthly.

“Pretty easy to use and could get the job done. However, the AI quality is pretty bad, lags a lot and does not act according to the prompt. Best to use another service.”
“It’s pretty bad… Out of all the Voice AI platforms i tried this was the worst one… the latency of the models is bad. Theres a 3-5 second pause after each turn. Also doesn’t appear to support to any model apart from gpt.”

“terrible customer service bot!! no support for UK to buy numbers so if from UK you will pay twice to make one call, they use lots of misleading terminology like import the number when really your just setting it up to work in VAPI. terrible service - GIVE UK NUMBERS”
“They provide no support to buy a UK number so you will end up paying twice to make 1 call if from the UK you have to import a number, then twillio will charge you as well as VAPI. Customer care bots are very bad!!! find a way not to use vapi if you can. ”
