Every image created on Tyzli carries two AI labels, as the EU AI Act asks: an invisible watermark inside the pixels and an “AI-generated” tag in the file metadata. Upload an image to check for both. The image is analysed in memory and not stored.
Results appear here in a second or two.
The watermark survives re-saving as JPEG or WebP, resizing and screenshots at full size. Heavy cropping, rotation or strong filters can remove it. The metadata tag survives only if the file was not re-encoded by an app that strips metadata.
A negative result means no Tyzli label was found, not that the image is human-made: other generators use their own marks.
