PolyAI is an enterprise voice AI platform for building dialog agents that resolve customer calls end to end, using its own Dialog-RSN-1 model and Dialog Studio.
About
PolyAI is an enterprise voice AI platform that builds conversational agents capable of handling customer calls and resolving them without escalation to a human agent. The company positions its product around "agentic dialog" — agents that manage critical business conversations across voice and text channels rather than simply deflecting calls.
The platform consists of Dialog Studio, a no-code-to-full-code environment for designing agent flows, tools, and brand voice, and Wren, a dialog agent that helps teams design, build, test, and continuously optimize the agents they deploy. PolyAI develops its own dialog models, including Dialog-RSN-1, an audio-native model that reasons directly over raw call audio to handle turn-taking, speech recognition, and response in a single model. Developers can sign up at studio.poly.ai, start free, and build with the ADK, MCP servers, or public REST and WebSocket APIs. Enterprise deployments run on the same platform under contract, with pre-built integrations into existing CRM and contact center stacks.

Who It's For
PolyAI targets enterprise contact center and customer experience teams in industries such as healthcare, financial services, insurance, hotels, restaurants, retail, telecom, travel, and utilities. Typical use cases include authentication, call routing, billing and payments, booking and reservations, account management, order management, troubleshooting, and FAQ handling. Developers building custom voice agents can use the self-serve API, ADK, and MCP tooling directly, while larger organizations typically deploy under an enterprise contract with pre-built integrations into their existing CRM and telephony stack.
