Cotabby

About Cotabby

Cotabby adds private, on-device writing suggestions to text fields across macOS. It predicts the next words as you type and lets you accept a suggestion with Tab, reducing repetitive typing without sending the contents of your documents to a remote service.

It suits people who write frequently in email, notes, browsers, and work apps but do not want a cloud-based writing assistant. The app runs locally and is designed to stay out of the way until a useful completion is available.

Cotabby is free. Performance and compatibility can vary between Mac apps, so test it in the software you use most.
