# Concepts

Core ideas worth modelling before you write code. Each topic is self-contained — skim the one you need.

- **[Architecture](/docs/scaigrid/scaiecho/concepts/architecture)** — How the routes, transcribe and stream services, dispatchers, and the two backends fit together.
- **[Streaming transports](/docs/scaigrid/scaiecho/concepts/streaming-transports)** — Picking between WebSocket and WebRTC for live transcription — control frames, audio plane, auth, and the trade-offs.
