PasteZen

About

PasteZen sits in the menu bar and cleans the clipboard the moment you copy, so there is no new paste shortcut to learn: fonts, colours and rich-text leftovers are stripped down to plain text before the paste ever happens. Pro goes further, removing tracking parameters such as utm_source and fbclid from links, rejoining lines broken by copying from a PDF, and masking API keys, card numbers and emails with a way to reveal the original. It can also clear the invisible zero-width characters some sites and AI tools embed. A floating Quick Action bar on Option Command V and a Services menu item apply one transformation on demand, a Rules window toggles every step with a live Playground, and you can write your own JavaScript transform in a sandboxed editor. A best-effort Co-Exist mode lets clipboard history apps still see the original copy. It is for anyone tired of pasting someone else's formatting into an email. The app is built without network access, so nothing you copy leaves the Mac. Plain-text cleanup, exclusions and undo are free; Pro is a one-time purchase after a 3-day trial. It needs macOS 14 or later.
