What It Does
This free online tool detects and removes invisible Unicode characters — often used for watermarking, fingerprinting, or text obfuscation — from any pasted content.
These hidden characters don’t visibly alter your message but can be used to track or embed metadata into text copied across platforms like ChatGPT, social media, messaging apps, and even documents.
Why Use It?
- Privacy Protection – Strip out hidden data potentially inserted by content generators or surveillance tools
- Clean Data Pipelines – Ensure exported or copied data is pure, clean, and ready for reuse
- Uncover Watermarks – Detect potential embedded signatures or traceable zero-width characters
- Secure Copy-Paste – Clean up suspicious or AI-generated text before using it elsewhere
- Educational Awareness – Learn how tracking via invisible text actually works
⚙️ How It Works
This tool scans your input for specific invisible Unicode characters known to be used for encoding hidden metadata:
| Unicode | Character Name | Description |
|---|---|---|
| U+200B | Zero-width space | Often inserted with no visual impact |
| U+200C | Zero-width non-joiner | Used in scripts to break ligatures |
| U+200D | Zero-width joiner | Connects characters without space |
| U+200E | Left-to-right mark | Affects bidirectional text direction |
| U+200F | Right-to-left mark | Can be abused to scramble layout |
You can analyze text for these characters and then clean them with one click — both actions show output clearly for your review.
Disclaimer
This tool only removes a subset of known invisible Unicode characters. It does not:
- Detect all possible steganographic or cryptographic watermarks
- Guarantee that removed characters were inserted for malicious purposes
- Provide legal advice or assurances about content reuse
Use ethically, at your own risk. You are solely responsible for how you process and share cleaned text.
