Problem
Notes, email, calendar, Drive, and a dozen chat threads each hold part of the picture — but none of it connects, and keeping any of it organized by hand doesn’t scale. A folder of markdown is a graveyard unless something actively files and links it.
Approach
Treat the vault as a system an agent operates, not a folder a human maintains. An AI agent is the librarian: it searches the vault first, then live sources, captures new material as structured notes with the right metadata, links them to what already exists, and keeps the indexes current. A chat bot handles capture on the move; a scheduled sync folds in anything new from the connected services. The human curates and decides; the agent does the filing.
Stack
An Obsidian vault as the store, an AI coding agent as the operator, MCP connectors for email / calendar / Drive / Notion, and a semantic-search layer so retrieval works by meaning, not just keywords. A periodic sync sweeps the live sources; captures arrive over a chat bot and get distilled in.
What shipped
In daily use: search-first retrieval across the whole vault, automated capture-and-link, a multi-source sync, and a mobile capture path. The agent maintains folder indexes and cross-links as it works.
What’s next
Tighten the capture-to-distillation loop and move more of the routing into reusable skills.
