PolyAI

PolyAI is an enterprise conversational AI platform for building and operating voice and chat agents that can resolve customer-service interactions rather than only answer questions. Typical use cases include bookings and reservations, account management, authentication, payments, order management, troubleshooting, call routing, and escalation to human agents.

1. Conversation technology: Raven is PolyAI’s default proprietary conversational model, with Raven 3.5 currently powering roughly 90% of Agent Studio implementations. In July 2026, PolyAI introduced Dialog-RSN-1, an audio-native model that jointly handles turn-taking, speech recognition, function calling, and response generation while directly processing the caller’s audio. Dialog-RSN-1 is currently recommended for English voice agents; existing customers can enable it, while new customers must request early access.
2. Enterprise workflows and integrations: PolyAI agents can retrieve customer records, create and update tickets, manage reservations, access knowledge, execute backend functions, and transfer conversations with context to live staff. The platform currently advertises 130+ integrations, including Salesforce, Zendesk, Genesys, Five9, NICE CXone, Amazon Connect, OpenTable, Epic, and other industry-specific systems. Custom HTTP APIs and external MCP servers can also be connected when a native integration is unavailable.
3. Build and deployment options: non-technical teams can build visually through Poly Agent Builder/Agent Studio, while developers can use the Agent Development Kit (ADK), a Python package and CLI designed for Git and CI/CD workflows. PolyAI also exposes REST APIs for programmatic agent management. Its Builder MCP wraps those APIs so MCP-compatible coding environments can create, configure, test, version, deploy, and manage PolyAI agents from an external development environment.
4. Commercial considerations: production voice-agent usage is priced per minute rather than through published self-service subscription tiers. PolyAI states that ongoing usage includes maintenance, proactive performance improvements, monitoring, platform upgrades, 24/7 support, and a 99.9% uptime SLA for phone lines. Exact per-minute rates are provided through its sales process rather than publicly listed.

PolyAI is most relevant to enterprises with substantial contact-center volume and complex integrations that need conversational agents capable of completing transactions, calling backend systems, and handing unresolved interactions to human agents within an existing CX stack.
