Watermarking hides an invisible signature inside AI-generated content — a statistical pattern woven into word choices or pixels that special software can detect later, though human eyes and ears never notice it. The goal: make ‘was this made by AI?’ answerable with proof instead of guesswork.
It matters as the more honest cousin of AI detectors — checking for a deliberate signature rather than guessing from style. The catch is fragility: rewording text or cropping and re-saving images can weaken the mark, and content from tools that don’t watermark carries no signature at all.
