Your AI
finally
remembers.
One shared memory for ChatGPT, Claude, and the AI tools you already use. It keeps track of your decisions, preferences, and projects — and brings them back exactly when they matter. No account. Nothing to set up in the cloud.
Private — stays on your computer · Works offline · Free & open source
Three steps. Then forget it’s there.
Connect your tools
One command sets it up and wires in the AI tools you use. The friendly wizard does the rest — just press Enter.
It remembers as you go
Decisions, preferences, and project details are captured quietly in the background. You never have to stop and save anything.
It recalls at the right moment
When you start a new chat or session, the memories that matter are already there — so your AI picks up right where you left off.
A memory your AI can actually trust.
Works across all your AI tools
ChatGPT, Claude, Codex and more share one memory — what you tell one, the others can recall.
It’s yours, in plain files
Your memory is a folder of plain notes on your computer. Read it, edit it, back it up. No lock-in, ever.
Finds the right memory
Smart search surfaces the most relevant memory for the moment — and shows you why it was picked.
Private by default
Everything runs on your machine. No account, no cloud, works fully offline. Stronger search is opt-in.
Free and open source
Every line is public on GitHub. Use it, read it, build on it — nothing hidden, no subscription.
How Memory Fort stacks up.
Like Mem0, Letta, Zep, and Cognee, Memory Fort distils durable facts from raw activity, supports semantic and graph retrieval, and exposes an MCP server.
Those tools are a service or library you wire into one application, and they need an LLM or embedder to be useful on day one. Memory Fort is a local folder of plain files — no database, no API key for basic use, and it captures automatically from many tools at once. The honest trade-off: managed clouds like Zep's temporal graph give you infrastructure you don't have to run yourself.
| Memory Fort | Mem0 | Letta | Zep / Graphiti | Cognee | Built-in (ChatGPT / Claude) | |
|---|---|---|---|---|---|---|
| What it is | Cross-tool memory vault | Memory layer / SDK | Stateful agent framework | Temporal graph memory | Memory engine + graph | Vendor's own chat memory |
| Where data lives | ✅ Plain files on your machine | Vector store (20+ backends) | SQLite / Postgres | Graph DB server (Neo4j / FalkorDB) | Embedded graph + vector | Vendor cloud |
| Zero API keys | ✅ Search + capture, no keys needed | ❌ LLM + embedder needed | ❌ LLM provider needed | ❌ LLM + graph DB needed | ❌ LLM + embedder needed | ❌ Vendor account required |
| Database server | ✅ None — just files | Embedded options exist | None by default | ❌ Graph DB server required (or Kuzu embedded) | None by default | Vendor-managed |
| Auto-captures across tools | ✅ Passive hooks, many tools | ❌ Wire your own app | ❌ Build on the framework | ❌ Wire your own app | ❌ Wire your own app | ❌ Single vendor only |
| Knowledge graph | ✅ Markdown + typed edges | ✅ Optional graph | △ Memory blocks (not a graph) | ✅ Temporal graph | ✅ Graph + vector | ❌ Opaque |
| Data portability | ✅ Plain text — git-ready | Export via API | Export via API / DB | Export via API / DB | Export via API / DB | ❌ Vendor lock-in |
Competitor details reflect each project's public documentation as of mid-2026 and will change — check their docs for current specifics. Memory Fort does not publish head-to-head benchmark scores.
Your memory stays yours.
Most “AI memory” lives on someone else’s servers. Memory Fort keeps yours where it belongs — on your own computer.

Questions, answered.
Is it really free?
Yes. Free and open source, no subscription and no account. The full code is public on GitHub.
Does my data leave my computer?
No. Your memory is kept on your own machine. The basic version works completely offline; smarter search is optional and opt-in.
Do I need to be technical?
Setup is one line you paste once, then press Enter. After that it runs quietly on its own and opens with a click.
Which AI tools does it work with?
ChatGPT, Claude, Codex, Antigravity, Claude Desktop, VS Code, and more — they all share the same memory.
Where is everything kept?
In a normal folder on your computer, as plain notes. You can open it, read it, edit it, and back it up like any other files.
How do I remove a tool or uninstall?
One command removes any tool cleanly. It only ever touches its own settings, so nothing else is affected.
