PasteZero

Local macOS clipboard manager that strips AI watermark traces

Desktopunknownworldwide

PasteZero is a local macOS clipboard manager that strips hidden AI watermark traces — invisible zero-width characters, unusual Unicode lookalikes, markdown quirks and curly quotes — before text is pasted, and includes an optional humanizer that lightly rewrites text to break AI statistical patterns. It runs entirely on-device and is aimed at macOS users who paste AI-generated text and want it cleaned of hidden markers first.
