Brainlogs remembers everything you saw, read, and promised on your computer — then answers questions about it. All of it stays on your machine.
Every day you read hundreds of pages, skim thousands of messages, and make promises in passing. By Friday, most of it is gone — not deleted, just unreachable. The thread you meant to follow. The pricing table you glanced at. The branch you abandoned and can't remember why.
Brainlogs runs quietly on your machine and keeps the text of what you see: window titles, pages, messages, terminal output. No screenshots, no cloud, no account. A small local model turns that stream into people, projects, and open loops, so you can ask a question in plain language and get back the moment — what was on screen, and what you did next.
It's the memory your computer should have shipped with.
Brainlogs reads the accessibility tree and window metadata as you work. Only text is kept, only for 30 days, and never from apps or sites you block.
People, projects, repos, and commitments are extracted on-device and linked to the moments they came from. This graph is small, encrypted, and yours.
Search by content, person, or time. Get the moment back — with everything else that was open — or let your coding agent ask on your behalf.
Spotlight searches file names. Brainlogs searches what you actually looked at — and rebuilds the moment around it, so you get the context, not just the hit.
"I'll send it by Friday" is a commitment the moment you type it. Brainlogs finds them in your messages, watches for evidence you followed through, and surfaces the ones you're about to miss.
Claude Code, Cursor, and Codex connect over a local MCP socket and query the same memory you do. They can leave notes, too — held as proposed until you approve.
Brainlogs is local-first the way a notebook is: there's no server to trust because there's no server. It's a log of your day, kept where your day happens.
Brainlogs isn't another place to write things down. It's the memory of everything you already did.
Free for individuals. One download, no account, nothing leaves your machine.
