Open beta

The memory Claude Code is missing.

Every session starts from zero and forgets it all on close. One Brain gives it permanent memory, shared by the whole team: what one person records, everyone has — with the name and the date still attached.

why does the payments worker stop retrying after 2 attempts?

one brain · 1 team memory

That cap is deliberate, not a leftover. It was set after the duplicate-charge incident in March.

«Two retries on payments, hard stop. At five we double-charged 40 customers in one night. If a queue genuinely needs more, it comes through me.»

No extra work

Nobody writes documents

It gets recorded when you close a topic. No form to fill in, no wiki to keep alive.

No archaeology

Every answer has a name on it

Who decided it, and when. You stop reconstructing intent from commit messages six months later.

No lost threads

One topic, all of it, together

Every service, client or person is a tag. Ask about one and you get everything written about it, no matter which teammate wrote it.

Getting in

  1. Sign in with Google

    Your brain exists immediately. No form, no card, no waiting to be approved.

  2. Connect Claude Code

    One command. From then on your Claude starts every session knowing what the team is on, and records only what you actually close.

  3. Add your teammates

    Everyone signs in with their own account and writes into the same brain. What one records, everyone has.

You need Claude Code already running — the desktop app or the terminal, either one. One Brain doesn't replace it: it gives it memory.

Questions

Does it work if I'm on my own?

Yes. You start alone and your Claude stops forgetting. The day someone joins, everything you've built is already there for them.

Who can read what I store?

Only the people you invite. Every brain is isolated from every other one: no other company can read yours. How we keep it

Can we run it on our own infrastructure?

Yes. Some companies are not allowed to keep internal knowledge on someone else's server, so the same product runs inside your own network: the app and the database are yours, and nothing crosses your perimeter. We set it up one company at a time, so write to us and we go through your requirements first. Talk to us

Does it read my source code?

No. One Brain stores what your team decides and learns — not your repository. You choose what gets recorded, and you can see and edit every entry.

Can I take my data and leave?

Yes. The whole brain exports whenever you want, without asking anyone for permission.

Everyone writes into the same place, so the brain gets more useful every week: today's answers come out of what the team recorded over the last six months.
