Detected form fields become editable inputs automatically; if there are none, you can type anywhere on the page. Add a hand-drawn or uploaded signature and place it exactly where it belongs.

Because everything happens on your device, sensitive forms — tax, HR, legal — are never exposed to a third-party server.
