Text cleanup, not detector evasion
| What this tool does | What it never does |
|---|---|
| ✓ Removes Markdown symbols and stray spaces | ✕ Rewrites your sentences or changes word choice |
| ✓ Clears hidden characters and extra line breaks | ✕ Tries to make text look human-written |
| ✓ Keeps your wording exactly as it is | ✕ Changes how AI detectors score a text |
| ✓ Gives you tidy, paste-ready text | ✕ Works as a way around detectors |
What stays untouched
- Your wording. The tool never rewrites sentences.
- URLs and email addresses, when “Keep URLs, emails and code untouched” is on.
- Code inside backticks and code blocks, including spacing.
- Everything stays in your browser. Nothing is uploaded or logged.
More free tools
Is my text uploaded anywhere?
No. Everything runs in your browser. Open your browser’s network tab while you type and you’ll see no requests carrying your text.
Does it change my wording?
No. It only removes formatting, hidden characters and extra whitespace. The optional intro and closing line removal deletes whole lines, and it is off by default.
Does it make AI text undetectable?
No, and it is not meant to. Detectors look at writing patterns, not formatting, so cleaning does not change the result. It is a cleanup tool.
Is there a hidden watermark in ChatGPT, Claude or Gemini text?
Not one made of invisible characters. Hidden characters in pasted text usually come from web pages and apps. Statistical watermarks, which are based on word choice, cannot be removed by a cleaner.
What are zero-width characters?
Characters that take up no space on screen, like the zero-width space and the byte order mark (BOM). They can break search, code and forms, so it helps to remove them.
Why replace em dashes?
Some styles and systems prefer a plain hyphen or a comma. It is optional. Choose “Keep” if you want your dashes left alone.
Can I keep my formatting when I copy?
Yes. “Copy with formatting” puts headings, bold text and lists on your clipboard as real formatting, so they keep their look in Word, Google Docs and email.
What do the presets do?
AI Text cleans the usual chat formatting. Plain Text also removes list markers and joins broken lines. Professional also removes intro and closing lines and repeated paragraphs. Custom is for your own choices.
Will it break my code or links?
No, when “Keep URLs, emails and code untouched” is on, which is the default. Code in backticks and code blocks, URLs and emails are left exactly as they are.
Can I undo a change?
Your original text stays in the left box, so nothing is lost. If you use “Use as original”, press Undo to go back.
Can I add my own rules?
Yes. Add up to six find and replace rules, with an optional regular expression switch.
