Your knowledge,in plain text.
A schema-disciplined Obsidian vault an AI keeps tidy — every note structured, linked, and findable. A second brain that grows itself.
A personal system I run — not a product.
A pile of notesisn't a brain.
A second brain isn't a tooling problem — it's a discipline problem. Structure is what makes notes compound, and structure is exactly what people stop maintaining.
Plain text in.Structure, links,and memory — out.
Just Markdown files in folders — nothing proprietary, yours forever. What makes it a brain is the contract every note obeys — frontmatter, the right folder, links to its neighbours — enforced on every edit. Structure never decays; it accrues.
fewer tokens per session — an assistant reads a few index files, not the whole vault.
it wires notes together, surfacing connections you'd never have drawn yourself.
Browse it likeyou'd open it.
The vault as you'd actually open it — the fixed 00–90 skeleton, real notes inside. Open a note to read it; click any frontmatter field to see what it buys you.

Milestones
Grew out of kickoff
Owned with maya
00-inbox is the only doorway — captures land there, then get a real home. Every other folder has a hub note indexing what lives inside.
The whole vault,as one brain.
Every node is a note; every line is a wikilink. Clusters are folders; the bright god-nodes are the hubs everything hangs off. Hover a node to light its links, or isolate an area.
Every line is a wikilink — many drawn by the assistant, connecting notes you'd never have linked yourself. As the vault grows the graph densifies: knowledge compounding. Drag to orbit it.
The difference,in a session.
Same question, same codebase. The only variable is whether the assistant has a structured vault to read.
Illustrative — token counts vary by repo and task.
The AI isthe librarian.
The discipline is enforced, not remembered — every edit runs through rules an AI never tires of, so a vault that's tidy today is still tidy in a year.

and it audits itself, on a cadence
It runs on a schedule — not just when you capture — sweeping the whole vault, fixing drift, and reporting what it changed. That's the difference between a folder and a second brain.
