Overview

Cotypist is a smart AI autocomplete application that runs locally on macOS to assist your writing across mail, messaging, and document tools. It provides real-time inline ghost-text suggestions that you can accept instantly with the Tab key.

Founder story

Cotypist was created by developer Daniel Gräfe. Frustrated by having to copy text into separate developer environments just to use smart code-completion tools, he built a universal, system-wide autocomplete utility designed to bring high-speed local AI writing assistance to every text box on macOS.
