Text Watermark
Embed/detect hidden text
This message will be invisibly embedded in the text
How Text Watermarking Works
- Uses invisible Unicode zero-width characters
- The secret message is converted to binary, then encoded as invisible chars
- Text looks identical but contains hidden tracking data
- Used by AI companies and publishers to track content sources
- All processing happens locally - your text never leaves your device
