Start here
GuardianMemory is one long-term memory that every assistant you use reads and writes. This is how it fits together, and what to do first.
The shape of it
Your memory bank lives at app.guardianmemory.com. Assistants reach it over MCP, the protocol Claude, ChatGPT, Cursor and most other assistants already speak. You give an assistant one URL, approve it once in your browser, and it gains exactly two tools:
| Tool | What the assistant does with it |
|---|---|
create_memory | Saves one durable fact about you as a plain sentence. |
search_memory | Finds what it needs by meaning rather than keywords. With no query it returns your profile. |
There is deliberately no third tool. Assistants retire outdated facts by saving the new version; you edit and delete in the web app.
Three steps
1. Create your memory bank
Sign up at app.guardianmemory.com. Email and a password, nothing else.
2. Connect your first assistant
Copy the endpoint and paste it wherever that assistant takes custom connectors or MCP servers:
https://app.guardianmemory.com/mcp
Step-by-step for Claude, Claude Code, ChatGPT, Cursor, Windsurf and VS Code →
3. Give it something to remember
An empty memory bank is not much use for the first week or two. Two ways to fill it:
- Import what your assistants already know. Paste a list into the Import page, one memory per line. ChatGPT users can copy theirs from Settings → Personalization → Manage memories; ask Claude to list everything it remembers, one fact per line.
- Just talk. Assistants are told to save durable facts as they come up. Mention that you write in British English, or which database billing runs on, and it gets kept.
Pin the things that always matter. Pinned memories lead the profile every assistant reads at the start of a conversation. Five or six well-chosen pins do more for the quality of answers than a hundred stray facts.
What you get in the app
| Page | What it is for |
|---|---|
| Memories | Everything held about you, newest first, with search. Edit, pin or delete any of it. |
| Activity | Which assistant saved or searched what, and when. |
| Connected apps | Every assistant that has been approved. Disconnect one and its access ends that second. |
| API keys | gdn_… keys for scripts and clients that cannot do OAuth. |
| Connect | Every snippet on this site, filled in for your account. |
Running it yourself
GuardianMemory is PHP 8 with no framework and no dependencies, PostgreSQL with pgvector for storage and search, Gemini for embeddings, and TypeSafe's Jev classifier for deciding when a new memory replaces an old one. The repository's README covers running it locally with Docker and deploying your own copy.
