AI Watermark and Metadata Removal FAQ

How do AI models embed hidden watermarks in texts and images?

LLMs like ChatGPT or Claude can insert invisible zero-width Unicode characters (ZWSP, ZWNJ), tag code points, or Cyrillic homoglyphs. Image generators like DALL-E or Midjourney embed C2PA manifests, EXIF software tags, latent frequency watermarks (SynthID), and PNG prompt chunks.
