Wondering what to do with your LinkedIn data export, your Google Takeout, an Instagram archive or a Slack export? The law makes every platform hand you a machine-readable copy, free. Each source below shows what the brain takes from it, where it lands, and the exact clicks to get it.
Your people, your voice, your interests, your places — and how the algorithms see you. One export or a combined archive; the same person in several exports becomes one note, matched by name.
LinkedIn

Link a local clone instead of uploading it: every document becomes a note in a generic taxonomy (strategy, product, engineering, customers, sales, finance, legal, compliance, marketing), with versions, duplicates and md↔pdf renders grouped and dates + authors from the repository history. A deterministic local scanner (no AI) keeps files with credentials, keys or dense personal data out as metadata-only notes.
What it gives your brain
Every document — Markdown, PDF, Word, Excel, PowerPoint, images, code
Category, document type and the customer / vendor it concerns
Version chains, byte-identical duplicates, md↔pdf/html renders
Authors (names only) and dates from the repository history

Studio → Sources → Git docs repo → Link folder… (nothing is copied or changed)
Drive for desktop folderTakeoutinstant (desktop sync)
Link the My Drive or shared-drive folder that Google Drive for desktop keeps on your computer (or an unpacked Drive Takeout). Every file becomes a document note in the same taxonomy; native Google Docs, Sheets and Slides come in as links to the online document. Files with secrets stay metadata-only, and cloud-only placeholders are never opened.
What it gives your brain
Every document in the linked folder
Native Docs / Sheets / Slides as links (id + URL only)
Category, type, entity, versions and duplicates

Install Google Drive for desktop and mark the folder “Available offline” — or unpack a Drive Takeout

How exports work
Your data is yours by law. Here is how to collect it.
GDPR Article 20, the EU Digital Markets Act and CCPA require platforms to give you your data in a machine-readable format, free.
01
Request the export
Every source above lists the exact clicks. Most exports arrive within hours; LinkedIn and X can take 24–48 hours.
02
Drop it in
On a source in Studio’s Sources, on your phone in Second Brain Mobile, or tell Claude Code or Codex “build my brain from this .zip”. Sources are detected automatically, even in a combined archive.
03
Update next month
An export is a snapshot. Drop a newer one and press Update: your edits and _notes/ are kept, and the update report says what changed.
Studio › Sources each export feeding John’s demo brain, and the ones still to add
Sources › LinkedIn the files the brain was built from — upload a newer export here
snapshotExports are snapshots — sharp on history, blind to this week until the next Update. A hosted, scheduled sync is on the roadmap.
Where it lands
One export in. A layered brain out.
Every source writes into the same typed brain — numbered folders of plain Markdown. Click a tile to jump to its source.
