1. Invisible Unicode & Markup Stripping
U+202F narrow spaces and markdown syntax. Cleared locally in your browser for free.
Clear ChatGPT formatting residue and invisible Unicode markers from your clipboard. Enjoy clean, unformatted paragraphs ready for any content editor.
ChatGPT's web interface routinely inserts narrow no-break spaces (U+202F) around numbers and units. It appears as a normal gap but acts like a glued character in spreadsheets.

Left uses U+202F (narrow no-break space). Right uses standard ASCII space (U+0020). The cleaner replaces the narrow space locally without rewriting words.

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.
