ℹ️ How It Works

The Perso Interactive Web SDK connects your web application to the Perso AI Platform through a real-time WebRTC session.

Integration starts by fetching available session settings (STT type, TTS type, LLM type, background image, prompts, and documents) creating a session ID using your API key, and then establishing a WebRTC connection in the browser.

Once connected, your application subscribes to chat states and events to render messages, control voice input/output, and handle tool calls in real time.
