Definition
Copying text from Microsoft Word, Google Docs, PDFs, or email clients often injects unwanted rich-text styling spans, non-breaking spaces (U+00A0), and erratic font sizes into your clipboard.
Clean Paste AI flattens these complex rich-text structures into pristine plain text instantly within your browser.
All processing runs 100% locally on your computer with complete confidentiality.
Optional Pro rewrites allow you to polish sentence cadence after formatting has been removed.
Technical Sources
Invisible Unicode artifacts, Markdown residue, and official statistical watermarks are three distinct mechanisms with different solutions.
| Mechanism | Technical Description | How Clean Paste AI Handles It |
|---|---|---|
| Invisible Unicode Artifacts | Zero-width spaces (U+200B), narrow no-break spaces (U+202F), and format code points copied from web UIs. | Free local in-browser scan and deletion. Visible words remain unchanged. |
| Markdown & Formatting Noise | Heading hashes, bold asterisks, code fences, and bracketed links. | Free local in-browser stripping to clean plain text. |
| Statistical Sampling Watermarks | Mathematical bias in token selection probability during model generation (e.g., Claude's official watermark). | Pro semantic sentence reconstruction. Rebuilds phrasing while keeping meaning intact. |
“Nothing is added to the text and there are no hidden characters.”
“U+200B ZERO WIDTH SPACE is intended for line break control without displaying a visible space.”
Markdown syntax adheres to the CommonMark specification: CommonMark Specification.
