## What we know about PolyAI

PolyAI is a voice ai platform: enterprise voice assistants. This profile tracks every PolyAI fact we have verified, each linked to a primary source and dated.

PolyAI does not publish a public per-minute rate we have been able to verify, so the price figure here stays blank until we can confirm one. We would rather show nothing than a guessed number; if you have a current PolyAI quote, it is the fastest way for us to close that gap.

On capabilities, PolyAI covers native sip trunking, warm transfer to human, built-in knowledge base, no-code agent builder, api-first (full lifecycle via api), and simulation/testing suite for agents, and does not offer self-serve signup. Each of those is verified against PolyAI's own docs or dashboard, not marketing copy.

On performance, PolyAI reports a median end-to-end latency around 300 ms. Latency figures are vendor claims until we measure them ourselves, and they are labeled that way on the PolyAI fact sheet, so treat them as a starting point rather than a guarantee.

PolyAI ranks the 6th-lowest latency of the 17 voice ai tools we track, but only 21st of 17 for languages, so where it lands for you depends on which of those matters more.

In total we track 12 verified facts for PolyAI today, each linking the primary source it came from so you can check our work - and vendor claims we have not measured ourselves are labeled as such on the PolyAI fact sheet below.
