Every new chat, you re-explain the deal, the thesis, the players — then it forgets. A second brain remembers all of it for you, and gets sharper every week. Obsidian + Claude, set up in an afternoon — free guide and a ready-made starter vault below.
No email gate. No sign-up. Built by Russell at SearchLoop.
An Obsidian vault is just a folder of plain text files on your laptop. Obsidian adds two things on top: a graph that shows how your notes connect, and [[links]] between them.
Claude — in the desktop app or Claude Code — reads that same folder and writes new notes back into it. No database. No vector search. No IT ticket. If you can keep notes in folders, you can run this.
The split is simple: Obsidian is the notebook — it shows your notes and how they link. Claude is the operator — it reads the notebook and writes new pages into it. The vault is just the folder they share.
Most "AI note" setups are just storage. This one improves itself, because the loop closes every time you use it.
Claude reads your vault for context — your thesis, the deal, the people, what you decided last time. It starts every task already knowing your world.
It does the job: summarise a 120-page CIM, prep a call, screen a target against your gates, draft the founder-to-founder note.
It files what it learned as new, linked notes — and updates the index. Nothing evaporates into a lost chat window.
The next session starts smarter than this one. That loop is the whole game.
This isn't a metaphor: Claude Code loads your standing brief every session and keeps its own running memory by default — it's documented.
Deals, the reading, and your relationships aren't three tools — they're one connected graph, and they compound together.
Thesis fit, your scoring, the open questions. Every touch adds to the picture instead of restarting it. Your pipeline becomes institutional memory, not a spreadsheet you dread.
Drop a CIM or PPM in; Claude writes the synthesis into the vault and links it to the deal. Months later you can still ask it what the margin bridge was.
Bankers, founders, advisors, LPs — a quiet graph of who knows whom, what you last said, and the next touch. The intro you need is one link away.
The banker links to the deal, the deal links to the CIM, the CIM links to your thesis. Open the graph and you see a living brain.

Pick the one that fits you. Both read and write the very same folder of notes — they're just different front doors.

claude from inside the vault folder.One difference worth knowing: Claude Code reads CLAUDE.md automatically every session. Cowork doesn't read it by name — you give it the same context once through Cowork's Instructions.
Two things stay separate: your notes live on your machine, but the text Claude needs to answer is sent to Anthropic to process it — same as any AI tool — and retention depends on your plan and settings. So don't load live LP data or NDA'd documents until your firm has signed off; do your first runs on a public or redacted deal. The vault's CLAUDE.md spells this out too.
It's not an empty template. It's a small, fictional lower-middle-market fund you can poke at — a live deal wired to its CIM, the banker who showed it, the founder, your thesis, and a four-gate scoring model. Open the graph and you can see how it connects from day one. Then make it yours.
