Was it made with GenVista?

What a GenVista mark says

Pictures, clips and songs made with GenVista generally carry two marks. They say that the file was made with AI, by GenVista, and how. They never say who made it: every file of a kind carries the same marks.

The signed label (Content Credentials)

A C2PA manifest inside the file, signed with GenVista's own certificate (“GenVista”, issued by the “GenVista Content Credentials Root 2026”, or by the earlier “GenVista Content Credentials Root” for files signed before 24 October 2026; both are published here). It records that the file was made by AI, from words (trainedAlgorithmicMedia) or from the user's own file (compositeWithTrainedAlgorithmicMedia), with the tool, the model and the time. Any C2PA reader can show it. It's lost when a file is re-saved or uploaded to most platforms, which is why the watermark is there too.

The invisible watermark

• Pictures: Adobe's TrustMark Q. 40 bits: “GVAI” in ASCII, a version (1), and the source, 1 for made from words or 2 for made from your own picture, with error correction (BCH_SUPER). The two full packets are 0100011101010110010000010100100100010001101100110111010000110101000111100101010011100000110101000000 and 0100011101010110010000010100100100010010100110000011010100101001101010110000110110111111000000100000.
• Clips: Meta's Video Seal 1.0. 256 bits: the same 40, repeated, mixed with a pattern of each source's own.
• Songs and clips' sound: Meta's AudioSeal. 16 bits: “GV” in ASCII for made from words, the opposite bits for made from your own file. It sits under what the music masks, so no one hears it.

The watermark survives what usually happens to a file: re-saving, resizing, a screenshot of a picture, re-encoding a clip or a song, sharing it on social media or in a messenger.

What the check can't tell you

• No mark found doesn't prove a file wasn't made with GenVista. Heavy edits can remove a watermark: tight crops of a picture or tilting it a few degrees, a song played faster or higher, a clip's colours pushed hard. And tools that only change your own file without making anything new, like splitting a song into its parts, add no marks.
• A watermark can't say who made a file, and GenVista's never does.
• Other companies' marks: the check tells you when a picture carries someone else's TrustMark, a song someone else's AudioSeal, or a file someone else's Content Credentials, but it reads only GenVista's in detail.

Nothing you check is uploaded, stored or logged. Your browser downloads the readers once, from our own servers (about 70 MB for a picture, 60 MB for a song and up to 125 MB for a clip), and does the rest itself. See our Privacy Policy.
