Cotypist is a local AI autocomplete utility for Apple Silicon Macs that predicts your next words in almost any text field. It runs entirely on-device, shows inline suggestions as you type, and accepts them with Tab. The tool targets people who spend hours writing email, docs, support replies, and AI prompts.
Key Features:
System-wide inline autocomplete: Shows AI suggestions in most Mac text fields and accepts them with Tab.
Local-only processing on Apple Silicon: Runs language models entirely on-device, keeping text private and latency low.
Style learning and personalization: Adapts to each writer's vocabulary and phrasing so completions sound familiar.
Typing helpers built in: Offers word-by-word acceptance, inline typo fixes, and emoji suggestions without extra pop-ups.
Pros
Noticeable time savings: Users often cut keystrokes significantly in email, support replies, and documentation.
Strong privacy posture: No prompts or documents leave the Mac, and password fields stay unread.
Stays inside existing workflows: Removes the need to switch to a chatbot or craft prompts to get help.
Cons
Limited platform support: Requires an Apple Silicon Mac running macOS 14 or later, excluding Intel, Windows, and Linux.
Heavy writers pay in money and memory: Subscriptions plus 1-2.5 GB RAM usage can feel costly to some users.
