deja
your prompts · every ai · one library

Your prompts are work.
Stop losing them.

You perfect a prompt, get a great answer — then it's gone in the scroll. Deja saves every prompt you send across ChatGPT, Claude, Gemini, DeepSeek, and Grok, and slips the right one back to you the moment you start to type it again.

how it works

It works the way memory should — quietly

Three steps, and you only do the first one. No buttons, no copy-paste, no folders to keep tidy — you work exactly as you do today and Deja does the remembering.

  1. 1

    Prompt like you always do

    Keep using ChatGPT, Claude, Gemini, DeepSeek, and Grok. Hit Enter — there's nothing new to learn and nothing to click.

  2. 2

    Deja remembers — privately

    Every prompt lands in a local library on your machine. Searchable, taggable, and never sent anywhere.

  3. 3

    The right one comes back

    Start typing something you've asked before and your best past version floats up — one click to reuse it.

Find it in seconds

Fuzzy search, tags, pins, and favorites. Sort by newest, most-used, or longest-unseen — built for a library of hundreds.

Yours to control

Pause capture in one click, switch off any site, or auto-pause in incognito. Filter out throwaways so only the keepers stay.

Yours to keep

Export and import JSON, export Markdown, or wipe everything instantly. No lock-in, ever.

one library, every assistant

Works where you already work

No single AI lab will let your prompt history follow you to a competitor. Deja will.

Switch tools whenever you like — your craft comes with you, the same library on every site.

privacy

Private by design — not by promise

Deja can't leak what it never sends. Everything stays in your browser.

  • No network calls, no telemetry, no analytics. Nothing you type ever leaves your machine.
  • No accounts, no cloud, no third parties. Your library lives on your machine, in your browser (local IndexedDB).
  • Only your prompt text is saved — never the AI's replies.
  • Credential-aware. Password, one-time-code, and payment fields are never read.
  • Pause anytime. One click stops capture everywhere; incognito windows are paused by default.
ready when you are

Stop rewriting prompts you've already perfected.

Install once, keep working exactly as you do, and let Deja remember the rest.
