Your workspace.

Everything you have made here, in one place: the prompts you saved and how they score, your Grader reports and tests, and what your API keys spent. Reuse any prompt in one click. It lives in this browser, and nothing in it reaches us.

Free planAll tools, no account. Your work stays on this device.

Check a prompt before you send it

The full Grader

The score and what the prompt leaves out appear here.

Keep your work safe

Everything here is stored by this browser, on this device. Browsers can clear site data to free space, so ask this one to keep it, and download a backup now and then. A backup also moves your workspace to another browser: download it here, then open this page there and restore it.

Backups never include your API keys; add them again in the other browser. To delete everything, use Keys and data.

What Pro will add to this page

Pro is not open yet, and everything above stays free. Pro is for the things that need our server.

  • The same workspace on every device, kept in sync and backed up, with your full version history.
  • A prompt written for you: ask for a task the repository does not cover, and get a tested prompt back.
  • No keys at all: improve, compare and test prompts here with models we provide, with a monthly allowance included.
  • A note when something changes, such as a model you rely on changing price or a saved test starting to fail.

Hear first when Pro opens

One email when Pro opens. Nothing else.
