How it works

One button. The prompt-engineering scaffold senior teams already use.

The floating button shows up where you already type.

Open ChatGPT, Claude, or Gemini, write what's in your head, click the button. The structured rewrite drops back into the same input, ready to send.

⌘ Shift O also works

Refine mode asks one or two sharp questions before rewriting.

For meatier tasks the model picks up missing context — audience, format, constraints — so the output isn't a generic guess. You answer in three seconds, you get a noticeably better result.
