Mark AI images with C2PA and an invisible watermark

Mark AI generated images with a signed C2PA manifest and an invisible watermark, log AI text and let anyone check the result. Free checker and a free plan.
I created Tellmark.si to serve the requirement as set out by EU AI Act Article 50, which has applied since 2 August 2026. It provides a signed C2PA manifest plus an invisible watermark that runs on the user's own servers. The file gets a marking and the text gets a hash and a label.
