Remove the Gemini watermark from text
Paste text from Gemini and every invisible character is named and counted before it is removed. The cleaner runs entirely in your browser: no upload, no account, no limit, and your visible words come back exactly as you wrote them.
Cleaning happens in your browser: that text never leaves this page, and there is no upload, no account and no limit. Rewrite is the exception — that one sends your text to our server.
SynthID and what it means for text
Google's SynthID marks AI output across text, images, audio and video. For images it is a pattern in the pixels; for text it is statistical, sitting in the model's word choice. A character cleaner reaches neither. What it does reach is the ordinary invisible debris that comes with any paste, and that is what this page is for.

Most of what people look for under that phrase is about images and video — the visible mark on generated pictures. That is a different job from this one, and a different tool.
Using this as a Gemini watermark remover
A Gemini watermark remover usually means one of two jobs. For pictures and video you want an image tool. For text — which is what this page is — you want the invisible characters gone, and that is what happens when you press clean. Free, no sign-up.
All assistants, one tool
The cleaner is the same on every page — it matches characters, not sources. See the full list of what it removes.
Questions
Does this remove the AI watermark from my text?
It removes the invisible characters — zero-width spaces, joiners, tag characters and the like — that get carried along when you copy text out of an AI assistant. It does not touch your words. Statistical watermarks such as SynthID live in the word choice itself, so no cleaner can remove those without rewriting your text - and the cleaner rewrites nothing. There is a separate Rewrite button for people who want their wording changed; that is a writing aid, not a way around detection.
Which AI assistants does it work with?
All of them. The tool matches characters, not sources, so text from ChatGPT, Claude, Gemini, Copilot, Grok, DeepSeek, Perplexity or Llama is handled identically. It catches the same characters when they come from Word, Google Docs, a PDF or a web page.
How many characters does it detect?
431 named characters, plus the entire private-use block. That includes the Unicode tag range U+E0000 to U+E007F — the block used to hide data inside plain text — which most cleaners miss.
Is my text uploaded anywhere?
The cleaner runs entirely in your browser: that text never leaves the page, there is no account, and there is no limit on how much you clean. The separate Rewrite button is the one exception — it sends your text to our server, which passes it to a language model. Nothing is stored either way.
Why does my text break my CMS or code editor?
Invisible characters survive a copy-paste but are not what they look like. A zero-width space inside a variable name breaks the code, a non-breaking space breaks a search, and a smart quote breaks a string literal. Nothing looks wrong on screen, which is what makes it hard to find.
