How Rapport Works (At a Glance)
The Two Main Components
1. Rapport Studio
A browser-based editor where creators design and configure characters. From here you can:
Build projects from templates or from scratch
Select characters, AI, and voices
Define personality and behaviour
Preview & test in real time
Manage projects, assets, and workspaces
💡 No installation needed — Rapport Studio runs entirely in your browser.
2. Rapport Session Runners
The “engine room” that powers live sessions. These cloud (or on-premise) servers handle:
Real-time voice and data streams
Communication with AI, STT, TTS, and animation services
Sending back audio and animation for rendering
Optimised for:
Low latency → fast responses
High concurrency → many users at once
Reliability → automatic fallback if a service fails
