Persona is a lightweight, open-source AI chat UI library that embeds into any website, from modern apps to static HTML. Unlike React-based chat frameworks, Persona is framework-free, backend-agnostic, and WebMCP-native, so your assistant can discover and execute tools exposed by the parent page. Add streaming chat, voice, theming, and interactive copilot experiences without rebuilding your frontend or writing bespoke APIs.
