What is Clean Paste AI?
Clean Paste AI is a clean paste tool for AI output. Text copied from ChatGPT, Claude, Gemini, Google Docs, email or a CMS often carries zero-width spaces, U+202F narrow no-break spaces, byte order marks and raw Markdown syntax. The tool works as an AI output cleaner and clipboard sanitizer, showing an itemized count of the residue it finds and then removing it while leaving the visible words and paragraph structure in place.
Invisible character detection and Markdown stripping run locally in the browser with JavaScript, so text is not uploaded for free cleaning, and the free tools need no login. Optional Pro features, a Text Watermark Remover and an AI Humanizer, rewrite wording on the server using credits. The site states openly that it does not promise AI detector bypass and that statistical watermarks such as Claude's live in word choice rather than hidden characters.

How to use Clean Paste AI
- 1
Paste your text
Copy text from an AI assistant or any web app and paste it into the Clean Paste AI workspace, or try the built-in sample.
- 2
Review the residue
Check the itemized count of zero-width characters, narrow spaces and Markdown tags detected in the draft.
- 3
Clean the text
Run the free local clean to strip hidden characters and Markdown, leaving plain text with the same words.

Use Pro rewrite if needed
When wording itself needs restructuring, switch to the Pro Text Watermark Remover or AI Humanizer, which use credits.
Clean Paste AI key features
Invisible Unicode character remover
Detects and removes more than 60 non-printing code points, including zero-width spaces, joiners, byte order marks and U+202F narrow spaces, which are normalized to standard spaces.
Markdown remover
Flattens heading hashes, bold asterisks, blockquotes, code fences and bracketed links into plain text ready for publishing.
Residue counts before cleaning
Shows exactly how many hidden characters and Markdown elements were found so changes are transparent.
Local, private processing
Free cleaning runs entirely in the browser; pasted text stays on the user's device.
Pro Text Watermark Remover
Meaning-preserving sentence reconstruction aimed at statistical sampling watermarks that cannot be removed by character cleaning.
Pro AI Humanizer
Rewrites stiff transitions and mechanical sentence pacing into more natural prose.
Clean Paste AI use cases
CMS publishing
Clean articles before pasting into WordPress, Webflow or Notion so invisible tokens do not break meta fields or layouts.
ChatGPT text cleaner for editorial teams
Turn AI chat transcripts into unformatted plain text for style review and editing.
Agency deliverables
Check client copy for stray Markdown and zero-width artifacts before sending final files.
Technical documentation
Normalize AI-assisted code comments and release notes before committing them to repositories or wikis.
