Remove the Perplexity watermark from text

Paste a Perplexity answer and get it back clean. 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 β€” that one sends your text to our server.

Cited answers carry the most debris

Perplexity's answers are stitched together with citation markers and formatting, so a copy often brings along more invisible spacing than a plain chat reply does. Paste one here and the tool will tell you exactly how much.

The citations themselves are not removed

Visible reference numbers are part of your text and stay put. Only characters with no visible form are taken out.

Using this as a Perplexity watermark remover

Looking for a Perplexity watermark remover or a way to clean AI text before you paste an answer into a document? This strips the invisible spacing that citation formatting leaves behind, and keeps every visible word and reference exactly as it was.

All assistants, one tool

The cleaner is the same on every page β€” 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 β€” zero-width spaces, joiners, tag characters and the like β€” 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 β€” the block used to hide data inside plain text β€” 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 β€” 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.
