Ce qui a changé, et quand
Every change to the detector or the wording, with the reason. Mistakes are listed too, because a record that only contains improvements is not a record.
- New mark and social cards. The old one was a tick in a rounded square, which is the badge every generated interface wears and which claims something has been approved. It is now four registration brackets around a point.
- Took the machine-made look off the writing and the page: 192 em dashes out of the English text, the indigo-violet accent, the centred symmetry, and a hand-drawn arrow pointing at the one large box on the screen.
- Wrote up the SynthID screenshot test as a guide, because the crop instruction is not documented anywhere and the uncropped answer is confidently wrong.
- Fixed a screenshot check that called any 1920x1080 PNG export a screenshot, and that could print 'this is a screenshot' underneath a verified cryptographic signature.
- Tested whether a SynthID watermark survives a screenshot rather than repeating what the documentation implies. It does, but only when the picture is cropped away from its surroundings first.
- Stopped the result card hedging four separate times about one finding while an item above it was badged as a strong sign.
- Recognised screenshots taken on macOS. They carry an XMP packet, so the old check, which required a file with no metadata at all, missed the most common screenshot there is.
- Removed advertising claims from the privacy policy and the FAQ. The site carries no advertising and the pages said otherwise.
- Calibrated the structural signals down hard after a reader reported real photographs coming back as probably AI. A false positive on a real photograph is worse than no answer.
- Cryptographic C2PA verification in the browser, including the binding between the signature and these exact bytes, which is the part a transplanted manifest is designed to defeat.
- Published the source under AGPL so the claim that nothing is uploaded can be checked instead of believed.
Written in English only. The entries describe specific edits, and translating them by machine into four languages would be worse than this note.
