Breaking Pen Keeps Its Writing Assistant on the Mac

Field notes

The workflow depends on macOS Accessibility permission to read a selection and write the transformed text back into the active application. Its model downloads once at about 1 GB, then runs locally; the page states that no account, telemetry, or network connection is required. Compatibility is listed as macOS 14 or later on Apple Silicon, with roughly 50 MB of idle memory use and automatic model unloading after ten quiet minutes.
