LLM Watermark Remover
Strip Invisible Watermarks
From AI-Generated Text
Modern LLMs embed zero-width characters, soft hyphens, and other invisible markers into the text they generate — fingerprints that survive copy-paste. This tool detects them and strips them out in one click. Runs entirely in your browser; your text never leaves your machine.

How It Works
Drop any AI-generated text into the box above — from ChatGPT, Gemini, Claude, or any other LLM.
Scan for invisible Unicode characters: zero-width spaces, joiners, soft hyphens, word joiners, and more.
One click removes every watermark and copies the clean text to your clipboard, ready to paste anywhere.
