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.

Frequently asked questions

No. It is a formatting cleaner. Detection tools analyse sentence patterns and word choice, not hidden characters, so removing invisible Unicode does not change what a detector sees. Anyone claiming a browser tool defeats detection is overselling it. Editing the writing itself is the only real answer.
No. Everything happens inside your browser. Nothing is sent to a server, nothing is stored, and closing the tab discards the content. That makes it safe for client work and unpublished drafts.
Yes. That is the point of this tool. Headings, bold, italics, lists, links, blockquotes, code blocks and tables are all preserved. Only unsafe tags and word processor junk are stripped, so you can paste straight into WordPress without rebuilding the structure.
Heavy em dash use is the fastest way for a reader to tell that copy was generated and never edited. A comma reads more naturally in business writing and matches most in-house style guides. If your style allows em dashes, untick that option and they stay.
Yes, and that is one of the strongest use cases. Word and Docs carry inline styles, class names and empty spans into your CMS. Tick Tidy pasted markup and the structure stays while the junk goes.
Copy formatted keeps the visual formatting for pasting into WordPress, Word or email. Copy HTML gives you the raw markup for a code editor or custom HTML block. Copy plain text strips everything to bare words for a text field or a prompt.
Yes. No account, no sign-up, no limit on how much text you clean, and no watermark on the output.
