PolyAI Voice Assistant

PolyAI builds voice and dialog agents that handle enterprise customer conversations by phone and across digital channels.

PolyAI Voice Assistant

PolyAI lets enterprises create, test, deploy, and monitor dialog agents for customer service. Agents can handle conversations such as bookings, account management, authentication, billing, routing, FAQs, and troubleshooting.

The platform supports no-code building through Agent Studio and developer workflows through its Agent Development Kit, CLI, and API. Pricing is usage-based per minute; the official pricing page does not publish tier prices.

  • Develop agents locally with the CLI and Python-based Agent Development Kit
  • Handle phone and digital customer conversations
  • Connect agents to enterprise tools through integrations
  • Apply conversation guardrails, policies, and brand rules
  • Review agent decisions and interactions across conversations
  • Use Dialog-RSN-1 for audio-aware voice interactions
  • Use Wren to analyze conversations and test agent improvements
