What we know about PolyAI

PolyAI is a voice ai platform: enterprise voice assistants. This profile tracks what we have verified about PolyAI, each fact 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.

In total we track 12 verified facts for PolyAI today, and add coverage as the ingestion pass revisits it. Where a number is a vendor claim rather than our own measurement, it is labeled as such on the PolyAI fact sheet below, and each row links the primary source it came from so you can check our work.

Whether PolyAI is the right call depends on your use case more than any single spec, which is why the head-to-head verdicts below score it per scenario rather than crowning one overall winner. Use the fact sheet for the raw numbers, and the matchups for how PolyAI actually fares against the platforms buyers most often weigh it against.
