PasteZero offers local cleanup for AI-assisted text on Mac

Summary

PasteZero is a macOS clipboard manager that offers to clean copied text and documents by removing hidden characters, unusual formatting, and other traces it associates with AI-written text. It displays original and cleaned versions of clipboard entries so users can choose which to paste, and opens clipboard search with Command-Shift-V. Users can also drop in a document to create a cleaned copy without altering the original. The site says processing runs entirely on the Mac, with no cloud connection, internet access, or third-party AI API, and that users can customize individual cleanup rules. Its examples include removing zero-width spaces, Cyrillic lookalikes, typographic punctuation, and Markdown markers, as well as applying Unicode NFKC normalization. PasteZero requires macOS Sonoma 14 or later. The listed launch offer is a one-time $9.99 payment for one Mac, including clipboard history and one year of updates; the page says the price will later rise to $17.99 and lists a 30-day money-back guarantee.
