The “ChatGPT Watermark Remover” That Removes Unicode, Not Watermarks

Field notes

The cleaner examines individual Unicode code points rather than attempting to rewrite prose. Its examples include zero-width characters, non-breaking and narrow no-break spaces, bidirectional controls, Cyrillic or Greek lookalikes, fullwidth forms, and mathematical alphanumerics. The page says the operation preserves visible words and line breaks, processes text in memory, and detects more than 900 characters. A separate API exposes the operation as JSON, while optional settings normalize em dashes and curly quotes.
