PolyAI
Agent platform
Self-serve platform for building, testing and deploying voice and chat customer-service agents on PolyAI's own models, through a visual studio, a Python ADK and CLI, REST APIs and hosted MCP servers.
Retell AI
Agent platform
AI copilot on every page of the Retell dashboard: told in plain language what to change, it proposes edits to a voice or chat agent for approval, generates simulation tests from real calls, filters call and chat history to explain failures, and builds analytics charts.
Platform for building, deploying and monitoring AI voice agents that handle phone calls: call transfer to humans, appointment booking, IVR navigation, outbound call campaigns and post-call analysis.
Text counterpart of Retell's voice agents: businesses build AI chat agents with the same prompts, functions and knowledge bases, or convert a voice agent in one click, and deploy them in a website widget, over two-way SMS or through a chat API, billed per AI message.
