High-signal invisible Unicode characters we clean
These code points appear most frequently in AI chat pastes and document exports. The full scan covers 60 characters; here are the common offenders.
| Code | Character Name | Why it breaks pastes |
|---|---|---|
| U+200B | Zero Width Space | Invisible separator; breaks word counts, search and URLs. Common AI/copy artifact. |
| U+200C | Zero Width Non-Joiner | Invisible; controls ligature joining. Often unintended residue. |
| U+200D | Zero Width Joiner | Invisible; joins glyphs/emoji. Can be watermark residue in plain text. |
| U+FEFF | Zero Width No-Break Space (BOM) | Byte order mark / invisible; corrupts leading text and parsing. |
| U+00A0 | No-Break Space | Looks like a space but blocks line breaks; breaks search matching. |
| U+202F | Narrow No-Break Space (NNBSP) | The main 'ChatGPT o3/o4-mini' artifact. Looks like a space, different code point. |
| U+00AD | Soft Hyphen | Invisible unless line wraps; splits words for search. |
| U+202E | Right-To-Left Override | Bidi override; strong spoofing risk. |
Our in-browser scanner checks the full catalog of 60 invisible code points, including directional controls and zero-width joiners.

Why Clean Paste Matters
Clipboard Sanitization vs. Sentence Restructuring
Sanitize clipboard contents by stripping zero-width junk and trailing formatting bugs. Ensure reliable copy-paste behavior across all word processors.
2. Pro Sentence Restructuring
Rebuild sentence clauses and transition templates to eliminate robotic AI phrasing.
100% Local In-Browser Execution
Our invisible character and markdown cleaners run directly inside your browser. No private text is ever uploaded for free cleaning.

Definition
Sanitize Your Clipboard for Tidy, Glitch-Free Drafts
01
Hidden zero-width characters and unexpected non-breaking spaces are among the most common causes of formatting corruption in modern publishing. They cause text to wrap unpredictably and corrupt spreadsheet formulas.
02
Clean Paste AI's Text Clean utility scans and purges digital residue directly within your browser. It restores clean typography and ensures that what you paste is exactly what you see.
03
No software installation or account creation is required for free local cleaning, making it fast and completely private.
04
When your draft requires deeper editorial revision, Pro rewrite reconstructs the text with organic human cadence.
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.
