A new colleague who doesn't need everything explained twice
Share one folder with a new colleague on day one. Their own AI reads the client's rules, decisions and history, and you only answer what the notes don't cover.
How it goes today
When someone new joins a client, the first week goes on explaining: the tone, the brand, what was already tried, what the client can't stand. Then the same questions come back a month later.
Your AIs share nothing with each other: every chat and every assistant starts from zero. Cobrain is the memory they all connect to, plain Markdown notes that Claude, ChatGPT, Claude Code or Cursor read and write.
How it works with Cobrain
- Keep the client's context in one folder: rules, decisions with their reason, what was tried.
- On day one, share that folder with the new person's email, read-only or read-write.
- They ask their own AI, which answers from the notes. You get the questions the notes don't answer.
An example note
clients/acme/decisions.md
- 12/09: no discounts in the newsletter. Why: it trained buyers to wait.
- 03/10: Instagram only, TikTok paused until January.What you need
Free works if they only read (up to 3 read-only shares). If they also write, Pro: up to 3 people write in a brain.

Agencies: every client's tone of voice, in every AI
Write each client's tone of voice once. Everyone in the agency, with Claude or ChatGPT, starts from the same rules, and a change is made in one note.
ReadWorkHanding work over from Claude to ChatGPT, without copy and paste
One person builds a report with Claude, the next one finishes it with ChatGPT. The data and the reasoning sit in shared notes, so nothing has to be exported or explained.
ReadWorkWork notes that end up in the right place
Stop losing work notes in chat history. Say «save this in the right place» and your AI files it under the client or project, for whichever AI you open next.

It is free and no card is needed. You sign in with a link sent by email, connect your AI and start building a memory that does not stay locked inside a chat.
