AI Text Cleaner
Paste content from ChatGPT, Claude, Gemini, Word or Google Docs and strip the hidden characters that break your CMS. Headings, bold, links, lists and tables stay exactly as you pasted them.
Your content
What to fix
Found in your text
What this tool does not do: it is a formatting cleaner, not an AI detector bypass. It removes stray characters that break layouts and paste badly into WordPress, Word and email.
It does not remove statistical watermarks, and no browser tool can. Some AI companies embed their text mark as a bias in word choice rather than as hidden characters, so stripping invisible Unicode has no effect on it. Only genuine rewriting changes the words themselves.
Why AI text breaks your CMS
Text generated by an AI assistant looks clean on screen, but it carries characters your publishing tools were never designed to handle. Those characters survive the copy and paste, then surface as broken spacing, odd symbols and layout gaps once the page is live.
Invisible characters
Zero-width spaces, word joiners and byte order marks sit between your words unseen. They break search and replace, split keywords, and confuse spell checkers.
Em dashes everywhere
The long dash is the clearest fingerprint of machine-written copy. Most style guides in business writing prefer a comma, and readers find it easier to follow.
Curly quotes and symbols
Smart quotes, ellipsis characters and non-breaking spaces render inconsistently across email clients, older browsers and plain text exports.
Word and Docs markup
Pasting from a word processor drags in inline styles, class names and empty spans. Your theme fights that markup and the published page stops matching your design.
Leftover markdown
Double asterisks and hash symbols arrive as literal text when an AI answer is copied outside its chat window, so headings and bold never render.
Structure you want to keep
Most cleaners solve all of the above by flattening everything to plain text. You then rebuild every heading, link and table by hand. This tool keeps that structure intact.
How to clean AI text in three steps
Paste your draft
Copy straight from ChatGPT, Claude, Gemini, Word or Google Docs into the editor. Formatting is preserved as it arrives.
Choose what to fix
Every option is on by default. Untick anything you want to keep, such as em dashes if your house style uses them.
Clean and copy
Press Clean text, check the report of what changed, then copy as formatted content, raw HTML or plain text.
What gets fixed, and what it becomes
Every replacement below is deliberate and reversible. Untick any rule you disagree with before cleaning.
| Character or issue | What it becomes | Why it matters |
|---|---|---|
| Zero-width space, joiner, BOM | Removed | Breaks find and replace, keyword matching and word counts |
| Non-breaking and thin spaces | Normal space | Causes uneven word gaps and stops lines wrapping properly |
| Em dash and en dash | Comma and a space | The most recognisable marker of unedited AI copy |
| Curly quotes | Straight quotes | Renders inconsistently in email, code and plain text exports |
| Ellipsis character | Three full stops | Some fonts and feeds drop the single-character version |
| Double spaces and tabs | Single space | Creates visible gaps once the text reflows on mobile |
| Word and Docs markup | Clean HTML | Inline styles override your theme and break your design |
| Leftover markdown | Real headings and bold | Otherwise asterisks and hashes publish as literal text |
