Chat cartography

Visualize a room's history as a 2D map of thematic clusters (from message embeddings). Zoom out for overview blobs. Zoom in to read messages in a cluster.

Console

Cartography (/cartography)

1. Select a room.
2. Generate or refresh map. The worker runs k-means on message embeddings and stores 2D coordinates.
3. Pan and zoom the canvas (RoomCartographyMap).
4. Click a cluster to list representative messages.

API

GET  /rooms/:roomId/cartography
POST /rooms/:roomId/cartography/rebuild

Rebuild is rate-limited. Cached coords live in D1 (room_cartography).

Requirements

Message embeddings must exist. Enable semantic search and run backfill from Settings → Search.

Honesty note

Conversation maps show up in research papers from time to time. This is an exploratory UX for large rooms, not a replacement for keyword or semantic search.
