Why This Tool Exists

Invisible Unicode characters are increasingly used as watermarks or steganographic markers in digital text. This tool helps you detect and remove invisible characters from text that might be tracking the origin of your content.

Recent findings such as "ChatGPT Models Seem to Leave Watermarks on Text" have raised awareness about how LLM-generated content might include zero-width Unicode characters as hidden identifiers.

Our tool is specifically designed to:

  • Detect zero-width Unicode characters that are invisible to the human eye
  • Clean LLM watermarks that may be embedded in text from AI systems
  • Strip non-printing characters while preserving the visible content
  • Remove ChatGPT watermark artifacts and similar hidden markers
  • Provide a clean version of text free from potential tracking mechanisms

This tool is open source and available on GitHub. Feel free to contribute or suggest improvements!
