What it does

A mirror for how you work with AI.

It keeps track in the background. Nothing to fill in.

  1. See every jump.How often you move between apps, and between which.
  2. Look back on a day or a month.What you worked on, and where the time went.
  3. Share your flow.Your day as one picture, with only the names of your tools on it.

A morning of work, brick by brick. Every change of mark is a jump.

No keystrokes. No screenshots.

A keyboard cut from stone, with a quill and an inkwellKeyboardNever logged.

It reads which app is in front and the prompt you write to your AI. Never the keyboard, never the screen. A test fails if anyone adds a way to. See the test

A padlock and its key on a block of stonePasswordsNever read.

Password fields and password managers are skipped. So are banking, mail and chat. API keys, tokens and card numbers are blanked before anything is saved.

Files in two folders on your Mac. No account, no server of ours. Delete the folders and it is gone.
