Clean Paste AI serves as a dedicated clipboard utility for professionals drafting with AI tools. It strips invisible Unicode elements, zero-width characters, and Markdown syntax from your text, preventing corrupted layouts in spreadsheets, CMS systems, and documents. The core utility is free and runs 100% in the browser without server processing. Users who need stylistic refinement can also access an optional Pro rewrite humanizer.
The free Invisible Character Detection and Markdown Stripper run locally in JavaScript: no private text is uploaded for free cleaning. They detect zero-width spaces, byte order marks, joiners, and 60+ invisible characters, and flatten headings, bold asterisks, blockquotes, and code fences into pristine plain text.
Key features:
- Invisible character detection (Free): 60+ non-printing Unicode code points, local browser
- Markdown stripper (Free): headings, bold, blockquotes, code fences to plain text
- Text watermark remover (Pro): semantic sentence reconstruction
- AI Humanizer (Pro): more organic, reader-friendly prose
- Exact residue counts and before-after paste preview
- No login or limits for the free tools
Typical use cases: content operations and CMS publishing in WordPress, Webflow, or Notion; editorial and copywriting teams preparing final drafts; agencies handling client deliverables; developers maintaining technical documentation. Teams that paste from several AI assistants at once also use the tool as a shared hygiene step before text reaches spreadsheets, search indexes, or ticketing systems, because corrupted layouts and broken formulas usually trace back to invisible clipboard residue rather than the destination app itself.
How it fits a daily workflow: copy from the assistant, run the paste through Clean Paste AI, confirm the residue count dropped to zero, then paste into the destination. The before-after preview makes the cleanup inspectable instead of trusting a blind strip, and visible words stay untouched in the free pass.
Pricing: Freemium.Pricing: Freemium. Free tools are $0 forever. Pro rewrite is credit-metered (10 credits = 1,000 words); guests can test up to 500 Pro words free and new registered accounts receive 10 bonus credits. Paid plans start at $5.99 per month.
Clean Paste AI is completely independent and has no affiliation with Anthropic, OpenAI, or Google. It does not claim AI detector bypass and is not an image watermark remover.
