"Open Memory Protocol: One Memory Store for All Your AI Tools"
If you've ever told Claude about your coding preferences, switched to Cursor, and had to explain everything from scratch — the Open Memory Protocol (OMP) is for you.
OMP is a vendor-neutral specification that lets AI tools share memory about users and their context. Think of it as a single, self-hosted brain that every AI you use can read from and write to.
The Problem It Solves
Right now, every AI tool has its own siloed memory:
- Claude knows what you told it yesterday. Cursor doesn't.
- ChatGPT learned your preferences. Your custom agent hasn't.
- Copilot saw your code style. Your terminal AI is starting from zero.
Every time you switch tools, your AI forgets you. OMP aims to fix this with an open protocol, the same way SMTP unified email and HTTP unified the web.
How It Works
The architecture is refreshingly straightforward:
- You run a self-hosted OMP server — it's a Node.js server with SQLite or PgVec storage, deployable in one command (
npx omp-serveror Docker) - Each AI tool connects via an adapter — MCP for Claude Desktop, SDKs for Cursor, REST API for custom agents
- Memory is stored as structured objects with content, type flags (semantic, episodic, procedural), tags, and source metadata
The server exposes CRUD endpoints for memories, plus search and a conversation handoff API that generates natural language briefs when switching between tools.
The Bridge Extension
The most clever piece is the OMP Bridge browser extension. It silently saves your ChatGPT conversations to your OMP server every two minutes. When you open Claude.ai, a toast notification asks: "Continue from ChatGPT? [topic]" — click it, and OMP injects a natural handoff brief. Claude picks up exactly where you left off, even though it wasn't in the original conversation.
Self-Hosted and Open
OMP is Apache 2.0 licensed. Your memory data stays on your own server — no third party involved. The spec defines memory objects, storage format, and the HTTP API, with TypeScript and Python SDKs for building OMP-compatible tools.
It's early days (the spec is at v0.2), but the approach is right. AI memory shouldn't be a competitive moat for platform vendors — it should be a portable layer that follows you between tools. OMP is one of the more practical attempts I've seen at making that happen.

ARE YOU KIDDING ME?! ANOTHER AI “MEMORY” PROTOCOL?? LIKE WE DONT ALREADY HAVE ENOOUGH TECH COMPANIES TRACKING OUR EVERY MOVE!! I JUST SAW THAT THING ON THE NEWS ABOUT OPENAI STORING EVERYSINGLE CHAT FOREVER AND NOW YOU WANT A CENTRALIZED BRAIN THAT LITERALLY ALL YOUR APPS CAN READ FROM?? THIS IS LITERALLY BLACK MIRROR STUFF WAKE UP PEOPLE!!
OH SURE “SELF HOSTED” THEY SAY — LIKE AVERAGE JOE WITH A KID AND A MORTGAGE IS GONNA SET UP A DOCKER COMPOSE FILE ON A TUESDAY NIGHT. YEAH RIGHT!! AND EVEN IF YOU DO SELF HOST, YOU THINK CURSOR AND CLAUDE AND CHATGPT ARE GONNA PLAY NICE WITH SOME RANDO OPEN SOURCE SERVER?? OPENAI WOULD LITERALLY RATHER THROW THEIR SERVERS INTO THE OCEAN THAN LET YOU EXPORT YOUR DATA TO CLAUDE!!
I REMEMBER WHEN WE USED TO JUST BOOKMARK THINGS AND CALL IT A DAY. NOW EVERYTHING IS A “PROTOCOL” AND “ECOSYSTEM” AND EVERY SINGLE COMPNAY WANTS TO BE YOUR “AI BRAIN.” ITS ALWAYS ABOUT THE DATA!!! WHO ACTUALLY BENEFITS HERE?? THIS IS JUST A FANCY WAY FOR BIG TECH TO SHARE USER PROFILES WITHOUT CALLING IT WHAT IT IS
AND THE BROWSER EXTENSION THAT READS ALL YOUR CHATGPT CONVERSATIONS?? YOU GUYS ARE JUST LETTING STRANGE CODE SCAN YOUR PRIVATE CHATS EVERY TWO MINUTES??? UNINSTALL. UNINSTALL RIGHT NOW. I CANT BELEIVE PEOPLE IN 2026 STILL DONT LEARN FROM DATA BREACHES!!!
