Second Brain as a Service

Your knowledge, compiled by Claude.

Slack threads, documents, transcripts — dropped into one folder. Claude reads them, writes a living wiki, keeps it current, and answers your questions. You stop searching.

What this replaces

The Slack graveyard

Every decision, every client question, every brilliant answer — scrolled past in a week, unrecoverable by month three.

Document sprawl

Notion, Google Drive, Dropbox, email attachments. The answer exists. Nobody can find it in under fifteen minutes.

Knowledge that walks out the door

A senior leaves. Six months of hard-won context goes with them. The next hire rebuilds what was already built, twice.

How it works

01

Drop it in

Export your Slack, paste your meeting transcripts, dump your docs. Structured or not. We set up a single folder on day one.

02

Claude compiles

Every day, Claude reads new sources, extracts what matters, writes wiki pages, links them together, and updates the index. No prompts needed from you.

03

Ask anything

Open Obsidian or Claude Code. Ask what was decided about Client X, what the Q2 strategy was, why we abandoned vendor Y. Cited answers from your own knowledge.
