PasteZero, the clipboard cleaner for AI residue

Field notes

The visible sandbox compares a 406-character source with a cleaned result and identifies the transformations it applied, including Unicode normalization, dash conversion, quote conversion, markdown removal, and trailing-space cleanup. The homepage also describes a clipboard-history workflow that preserves both versions and a file workflow that returns a cleaned copy without modifying the original. The downloadable Mac app is presented as local and private, with Accessibility permission required for its system-level operation.
