💡 よくあるご質問 (FAQ)

What is a ChatGPT zero-width watermark?

AI generators and web interfaces frequently embed invisible Unicode characters (such as Zero-Width Space U+200B or Word Joiner U+2060) between words. While invisible to human eyes, scanners and parsers detect them immediately.

How does the Zero-Width Space Remover work?

The tool scans your text for over 15 specific invisible Unicode code points and control characters, highlights them visually in red tags, and strips them cleanly without altering your visible text.

Can invisible characters break code and JSON files?

Yes! A zero-width space inside a JSON key, SQL query, or Python variable name is invisible but treated as a distinct character, causing mysterious syntax errors.

Is my text sent to any remote server?

Zero bytes are sent. The entire regex scanning and cleaning pipeline executes locally in your browser RAM.

Does removing watermarks bypass AI detectors?

It removes physical Unicode watermarks and formatting fingerprints. However, linguistic tone and sentence structure may still require manual human editing.
