Cotypist

Cotypist is a Mac app that suggests the next words you're about to type, right where you're typing them. Think of the predictive text on your phone, but for every Mac app — email, Slack, Notion, your browser, even the terminal. It runs locally on Apple Silicon, so nothing leaves your computer. Press Tab to accept a suggestion, or keep typing if you don't want it. The predictions adjust to your vocabulary and phrasing within minutes, making the tool feel like it's finishing your sentences before you finish them yourself.

What sets Cotypist apart is how it stays out of your way. There are no pop-ups, no chatbot windows, no context-switching. Suggestions appear inline in the text field you're already using. The tool learns your style as you write — names, technical terms, the way you start sentences — and gets better over time. It also catches typos in real time, offers emoji completions when you type a colon, and works with non-English text (it's been tested with Norwegian, Hinglish, and more). Because everything runs on your Mac, privacy isn't an afterthought; it's the default.

The biggest win is for anyone who types a lot. Writers, customer support reps, marketers, developers writing documentation — all of them can cut keystrokes significantly (the site claims up to 50% less typing). It's also genuinely useful for people who find typing physically difficult: non-native English speakers, dyslexic typists, those with hand arthritis, or anyone typing one-handed. Cotypist doesn't replace your writing; it just makes the mechanical act of getting words onto the screen faster and less tiring.
