DoppelBrain Connect
Give any AI agent long-term memory. Connect your personal knowledge base to ChatGPT, Claude, Cursor, or any MCP-compatible client and recall anything you've browsed.
Open your plugins
Go to chatgpt.com/plugins, click the + in the top right, then pick Create app. Not Create plugin, that one just opens a chat. In the dialog that opens, click Create MCP App. You do not need a paid plan.

Sign in
A window opens for you to sign in to DoppelBrain. That is what gives ChatGPT access to your memory.
Available MCP Tools
Once connected, your AI gets five tools. They return what you did and read as moments in time, with links to the pages and their own words, on your local clock.
| Tool | What it does |
|---|---|
recall | Anything about your past: "when did I last…", "what happened with X", the exact price, link or quote |
timeline | A day or a period, in order: "what did I do on Tuesday", "my week", "today so far" |
open | More about a moment or a page from a result: its pages, links and text |
find_page | A specific page or website (e.g. "what did I read on github.com"), and your coding-agent sessions |
save_knowledge | Save a note from the conversation to your DoppelBrain |
Requirements & Authentication
