PolyAI builds voice AI agents that answer and resolve customer phone calls, with support for chat and SMS on the same agent. Teams design and test agents in Dialog Studio, run them on PolyAI's own dialog models, and connect them to CRMs, telephony and booking systems so the agent can authenticate callers, route calls, take payments or make reservations. Customer facing and revenue teams use it to handle high call volumes and recover bookings that would otherwise go to voicemail.
