Check if an image was made with AI

Many AI tools now label their pictures: signed Content Credentials, AI tags, or an invisible watermark. Fildok reads these signals and tells you what they say and whether they are intact. It doesn't guess from the look of the picture.

Why use it

  • Verifies signed Content Credentials (C2PA) from OpenAI, Adobe, Google, Microsoft, Anthropic and others.
  • Shows the edit history: which tool made it and what changed afterwards.
  • Read in your browser: the picture isn't uploaded (the optional watermark scan sends only a small copy).
