1. Zero-Width Tag Stripping
Removes invisible Unicode tags, joiners, and non-breaking spaces locally on your machine.
Scrub automated copy exports to eliminate hidden zero-width tags before layout work. Streamline content formatting and ensure crisp, predictable typography.
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.

Hygiene advantages
Scrub automated copy exports to eliminate hidden zero-width tags before layout work. Streamline content formatting and ensure crisp, predictable typography.
Removes invisible Unicode tags, joiners, and non-breaking spaces locally on your machine.
Reconstructs repetitive sentence structures into engaging, reader-friendly prose with Pro credits.
Invisible character removal and Markdown stripping execute 100% locally in your browser session. Your draft text is never transmitted to our servers during free scans.
Workflow
Drop raw text from your AI writer into the tool to inspect for hidden formatting tags.
Click Clean to strip invisible codepoints and normalize whitespace instantly.
Paste spotless plain text directly into Figma, InDesign, or your CMS template.
Capabilities
Eliminates zero-width spaces, ZWNJ, non-breaking spaces, and 60+ non-printing codepoints entirely inside your browser.
Flattens bold stars, header hashes, blockquotes, and list indicators into uniform plain text ready for copy editors.
Reconstructs entire sentence structures when models embed statistical sampling signatures into word choice rather than hidden tags.
Softens formulaic phrasing and robotic sentence rhythm to create a fluid, authentic reading cadence.
Text Hygiene Concept
When layout designers and editors import raw text generated by artificial intelligence into Figma, InDesign, or WordPress, hidden zero-width tags frequently corrupt text frames.
These invisible characters distort leading, cause unexpected overflow warnings, and break text wrapping around visual assets. Fixing these bugs manually slows down editorial velocity.
AI Text Cleaner eliminates these layout roadblocks instantly. Our client-side scanner audits text against 60+ known non-printing Unicode positions, stripping every rogue byte in milliseconds.
By running exports through Output Cleaner AI before layout assembly, design and editorial teams ensure smooth, predictable typography every time.

| Mechanism | What It Embeds | Effective Solution |
|---|---|---|
| Unicode / Paste Residue | Zero-width spaces, U+202F, non-printing codepoints | Free client-side scanner & stripper |
| Markdown Clutter | Raw asterisks, header hashes, blockquotes, code fences | Free Markdown cleaner |
| Statistical Token Sampling | Cryptographic token selection bias (Claude 2026) | Pro full-sentence reconstruction |

“"Format controls and invisible characters can disrupt string comparison, rendering, and text security if not properly sanitized."”
