An Obsidian vault of plain markdown with an AI agent layer on top. The vault is the permanent record. The agent is the staff.
Crypt is a personal knowledge management system. At its core, an Obsidian vault: a folder of plain markdown files with YAML frontmatter, tags, and backlinks between notes.
On top of the vault sits an AI agent layer. The agent processes incoming files, maintains structured notes, surfaces connections between ideas, and writes daily intelligence briefs. It reads and writes the vault directly through MCP integrations.
Everything stays current without touching anything after the initial input.
Every note carries YAML frontmatter with at minimum a type, created date, and tags. One tag taxonomy across the whole vault. Backlinks connect everything: people to companies, clients to government landscape, projects to the clients they serve.
| Function | Behavior |
|---|---|
| INPUT PROCESSING | Takes raw files from Working/Input/, meeting transcripts, voice memos, research docs, and turns them into structured vault notes with proper frontmatter, tags, and backlinks. |
| CLIENT BRIEFS | Produces memos, talking points, and position papers for client audiences. Loads the client file, checks government landscape notes, verifies minister names, and writes in the right voice. |
| MEDIA MONITORING | Scans news sources, builds daily digests, flags developments relevant to active clients. |
| DAILY OPERATIONS | A combined intelligence product covering media, action items, contracts, travel, and anything else that needs attention. |
| STALENESS CHECKS | Any factual claim about government officials, policy status, or financial data older than 30 days gets flagged and verified via web search before use. |
Detto is the capture layer. Crypt is everything that happens after. A meeting ends, the transcript drops into Working/Input/Meetings/, and the agent picks it up: extracts action items, updates the relevant client file, links the attendees, logs it in the daily note. I step in when something needs a judgment call, and not before.
No vendor lock-in, no proprietary database, no sync issues. Every note is a .md file readable in any text editor, greppable from the command line, movable to a different system tomorrow. The vault syncs across devices. The working directory stays local.
The constraint is deliberate: nothing in the vault except .md files. No PDFs, no Word docs, no spreadsheets. Binary files live in the working directory. The vault is pure knowledge.
