Déjà captures your best AI prompts and replays them anywhere — so you stop rewriting from memory and start knowing if your model actually changed.
One email. When it's ready.
You wrote a prompt that worked. Then the conversation expired, the tab closed, or the model quietly updated — and you've been chasing that result ever since. Déjà remembers it for you.
Hit your capture shortcut and any prompt goes straight to your local library — timestamped, searchable, and yours. No account. No cloud. No one else's servers.
Select a saved prompt from the menu bar and replay it into whatever AI you're using right now. ChatGPT, Claude, Gemini — it doesn't matter. Déjà just copies it, ready to paste.
Run any prompt multiple times and see a simple diff of the responses. Finally know whether your model updated, or your prompt just drifted.
Déjà is a lightweight desktop app that lives quietly in your system tray. No account required. Your prompts stay on your machine in a local database. We're building this in public — this is the waitlist, and your early feedback shapes what ships.
Join the waitlist and get early access when Déjà is ready. No spam. Just one email.
