DrawDog

Clients are starting to ask freelancers to prove their work wasn't generated. DrawDog sits in your menu bar and records how your file grew, what apps were in front of you, and whether an AI tool was ever open. It signs and timestamps that record, then gives you one link to send. The client drags your file onto the page to confirm it's the one you certified. It never looks inside your work: no screen recording, no keystrokes, no file names. Three certificates a month, free.
