CoBot

Semantic search for co-ops, commons and community organisations worldwide, powered by the Murmurations protocol and OpenStreetMap.

Live: cobot.murmurations.network

What it does

• Searches organisations by topic and location using AI-powered semantic search
• Chat and search modes with an interactive map
• Users can submit their own Murmurations profiles for instant indexing

Stack

• Vanilla JS frontend with MapLibre GL for maps
• Transformers.js (all-MiniLM-L6-v2) for embeddings
• Express server (local dev) / Vercel serverless (production)
• Claude Haiku for query understanding and chat

Running locally

npm install
cp .env.example .env  # add your ANTHROPIC_API_KEY
node server/index.js

Open http://localhost:3000.

The ANTHROPIC_API_KEY is optional — without it, chat mode is disabled and search still works.

Data

Profile data comes from the Murmurations Index API and OpenStreetMap via the Overpass API. Run node scripts/fetch-profiles.js and node scripts/fetch-osm.js to rebuild the dataset.
