Perso Interactive SDKReal-time AI avatar sessions for the web

WebRTC-based SDK with LLM chat, TTS/STT, and client-side tool calling.

WebRTC real-time

Sub-second latency video/audio sessions with an AI avatar, powered by RTCPeerConnection and a typed DataChannel protocol.

First-class streaming responses, message history, and conversational state machine (RECORDING / LLM / ANALYZING / SPEAKING / TTS).

Built-in STT and TTS pipelines with locale-aware results and normalized text.

Expose local functions as ChatTool so the LLM can invoke them inside the session.

Dedicated server subpath keeps your API key off the browser — works with SvelteKit, Next.js, and any Node.js server.

Strict TypeScript types, structured error hierarchy, and Jest test coverage for the session lifecycle.
