AI research agent triggered by Core Devices Pebble Index01 ring notes: n8n + Obsidian (Self-hosted LiveSync/MinIO) + MCP servers
Turn a voice note captured on your Core Devices Pebble Index 01 ring into an auto-researched, auto-tagged note in your Obsidian vault — no manual copy/paste required.
Status: fully validated end-to-end on a real deployment, including a real ring recording — trigger, agent, web research, and sync-back all confirmed working (see Project Status).
→ docs/SETUP.md has the full step-by-step deployment guide. This README covers the what and why; docs/SETUP.md is what you actually follow to deploy it yourself.

Every research note gets a clear title, 2-5 topical tags, and two fixed tags applied to every note this workflow creates — interests and questions — plus a source link back to the original voice note. Customizable (see Reconfiguring things later).
- No Docker Desktop needed — everything runs on a headless Ubuntu server via plain docker-ce + the compose plugin. - No Obsidian REST API / no running the Obsidian Electron app on the server — the vault is mirrored to plain Markdown files on disk using livesync-cli, the official headless compan
