Shared AI memory across Claude, ChatGPT and Gemini

Give Claude, ChatGPT and Gemini one memory: connect each to Dexi’s MCP server and they read and write the same notes, so context saved in one assistant is there in the others.

Each AI assistant keeps its own memory, and none of them can see the others’. A decision you talked through in ChatGPT isn’t there when you open Claude Code, and Gemini doesn’t know what either one learned. Each memory belongs to the app, not to you.

Dexi’s MCP server turns that around. Connect Claude, ChatGPT and Gemini CLI to the same Dexi workspace and they all search and save notes in one place, your account. Something one assistant writes, another can find with a keyword or meaning-based search.

Why it matters

The memory belongs to you. It lives in your notes, which you can read, edit, tag, link and export like anything else in Dexi. Switching assistants, or using three at once, doesn’t mean starting from scratch. If an assistant saved something wrong, you fix the note and every assistant sees the fix.

You also know where each memory came from. Every note an assistant writes records which app created it and which app last edited it, and the tools return that to the other assistants. One assistant can tell a decision you typed yourself from something another assistant summarized. If you’d rather the assistants not read your whole archive, restrict each connection to one folder or tag, and their memory stays inside it.

Who gets the most out of it

Example: A developer moving between assistants in one week

You’ve connected Dexi to ChatGPT, Claude Code and Gemini CLI, and pasted the same short memory instructions into each.

  1. Monday in ChatGPT, you settle on Postgres over Redis for the job queue. ChatGPT saves a note: “Queue backend: Postgres, not Redis — fewer moving parts,” tagged #memory #atlas.
  2. Tuesday in Claude Code, you ask it to add a retry policy. It searches Dexi first, finds Monday’s note (written by ChatGPT, the result says), and builds on Postgres without asking again.
  3. Wednesday in Gemini CLI, you change the retry ceiling. Gemini appends the new limit to the same note instead of starting another one.
  4. In Dexi, the note shows it was saved by ChatGPT and last edited by Gemini CLI, with the whole history in one place you can read and edit.

None of the three assistants had to remember anything themselves. The memory lives in your Dexi notes.
