Technical Sources
How the Three AI Output Traces Differ
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.
