HOW AI TEXT WATERMARKING WORKS

Summary from the TLDR Marketing newsletter

Claude's text watermarking will be difficult to remove without heavy edits. Instead of visible characters, AI watermarks hide in word choices, using secret statistical patterns that can survive copying. Detection requires the provider's secret key and enough text to distinguish the watermark from chance, making it different from style-based AI detectors. Light editing or paraphrasing can weaken the signal but may leave enough original wording to remain detectable.
