Handing 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.
How it goes today
You spend hours with Claude on a report: data, context, conclusions. Then someone else has to lay it out, and they use ChatGPT. Usually that means exporting files, a long message, and a call to explain what matters.
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
- At the end of your session, ask Claude to save the data, the reasoning and the open points in a note.
- The other person has that folder, and their ChatGPT is connected to Cobrain.
- They ask ChatGPT to read the note and get on with it. No export, no call.

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.

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.

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.
