One memory across Claude Code, Cursor, and Codex
"Last time you were fixing the login flow. It broke because the token expired. Your goal: ship by Friday. 3 days left."
You didn't explain anything. You didn't keep a notes file. Window Memory handed your AI the full picture: where you stopped, and the reason behind every decision. And the moment your AI drifts off your goal, it catches it. It's not a notes app — it's a supervisor.
npx -y window-memory init
Don't want to touch a terminal? Paste it into Cursor or Claude Code and let it set itself up.
Works with Claude Code, Cursor, and Codex. One line to set up. Free.
Local-first. Free on your machine — your key, your data. Pro adds sync and AI included.
Your AI reaches for something you already threw away, or drifts off your goal. Window Memory catches it — before it ships.
This is the part that isn't memory at all — it's a supervisor. When you can't read every line yourself, it keeps your AI building the right thing. Open the dashboard any time to watch what your AI's been doing, one decision at a time — you don't have to be a developer to follow it.
Open a new session and just say hi. It's already caught up — what you changed, why you changed it, and what's left before your deadline.
Other tools can read your code — but not the reasoning behind it. Open a different tool and Window Memory still knows why you made each call — the part that's in no file — so your AI never re-litigates a decision you already made.
Reading your files tells your AI what the code is today — not why you chose this over the thing you already tried and dropped. That reasoning lives only in Window Memory, and it follows you into every tool.
Nothing to set up. Nothing to maintain.
Your project's goal is fed to your AI on its own — every session, and again every time it gets back to work. Set it once or let Window Memory draft it from your work, then steer it from the dashboard. You never sit down to configure anything. Install once and it starts on its own after every reboot — running quietly in the background, nothing to restart or babysit.
I'm not a developer by background. I build with AI tools — Claude Code, Cursor, Codex — and the thing that hurt most was this: my AI forgot everything between sessions.
I'd go in circles without realizing it — retrying things that had already failed, undoing decisions I'd made for a reason, burning tokens. By the time I noticed I was looping, I didn't even know where to start fixing it. If you didn't write the code yourself, that's a rough place to be.
So I built Window Memory. It doesn't just look at git or your code — it remembers how your project was actually built: the intent, the reason, the result, and the failures behind each step. So your AI keeps the context, and stops walking you back into the same wall.
One line and the loop-breaker is on. Your AI remembers the why behind every decision — your key, your data, your computer.
Pick up on any device, watch new decisions land live on your phone, and — across the projects you keep on Pro — ask your AI to read a past project and apply it here.
Invite teammates and everyone's builds pool in one place — who did what, with which tool, and every wall they hit. Your AI avoids the whole team's failures, not just yours.
Run npx -y window-memory init — one line, once.
Keep working in Claude Code, Cursor, or Codex. Nothing changes.
Open your next session — your AI already knows where you stopped, and why.
It keeps running on its own after every reboot. Install once, never think about it again.
Not a walled garden. Plug your project's memory into whatever you already use — free, on your own machine.
Pull your project's history, decisions, and context into anything you build.
Your AI tools tap into it natively and search by meaning — not just keywords.
Issue safe, rate-limited keys for Zapier, n8n, or any automation you set up.
Take over a teammate's work and your AI already knows the whole story — every decision they made, and every wall they already hit. Handoffs in minutes, not weeks.
Free is solo, on one machine. Pro follows you to every device — open it on your phone, anywhere.
Free forever
Perfect if you mostly stay on one machine.

Does it see my code?
No. Sensitive data is stripped before anything leaves your computer. On Free it runs on your own AI key; on Pro the analysis is included — no key to manage — and we never keep your raw sessions.
Do I have to keep it running, or restart it?
No. It starts on its own every time you turn your computer on and runs quietly in the background. You install it once.
I installed it but my first session didn't catch up?
If your editor (Claude Code, Cursor, Codex) was already open when you installed, just restart it once — it picks up Window Memory on the next session. After that, every new session is caught up automatically.
Will it touch my CLAUDE.md or existing setup?
No. It runs alongside your tools and never edits your rules files. If you like them, keep them.
Can it use what I figured out in my other projects?
Yes — on Pro, where you keep all your projects (Free keeps one). Each project's memory stays separate by default; nothing auto-mixes. But you can pull across the projects you've built with Window Memory on demand: search a past one and bring a decision or lesson into the one you're building now. You stop re-solving the same problem in every new repo.
What does it cost?
Free on your own computer — bring your own AI key. Pro ($15/mo) includes the AI — no key to manage — and follows you across every device and your team. New accounts start with a 3-day Pro trial — no key, no card.
Can my own tools and automations read it?
Yes. Your memory isn't a walled garden — connect it to the tools you already use. Your AI tools read it directly, and you can issue safe, one-click keys for Zapier, n8n, or any automation you set up.
Can I cancel or get a refund?
Pro subscribers: open the dashboard → Settings → Plan & billing → Manage billing. That opens Polar, where you can cancel, update payment, or download receipts. Cancel anytime — access continues until the end of your paid period, then you're back on Free with your local data. Refunds follow Polar's policy; if something went wrong, email hello@windowmemory.com.
Need help?
Email hello@windowmemory.com — a real person (the developer) reads every message.
