Local AI Autocomplete in your voice, anywhere on your Mac
Cotypist is smart autocomplete for the Mac apps you already write in: Mail, Slack, Notes, docs, even AI prompts. Press Tab when a suggestion fits, or keep typing and watch it update in real time. Runs locally on your Mac. No cloud, no API calls.
Hey everyone, I'm Daniel, the developer behind Cotypist.
First, a quick thank-you to the Product Hunt team. After Cotypist launched back in May, they reached out and invited me back for a featured relaunch. I'm honestly a little stunned by that, and very grateful to be here again.
A few years ago, I noticed I'd developed a weird habit: copying conversations into Visual Studio Code, just to get GitHub Copilot's inline completions, then pasting them back into the app I should have been writing in. After enough of that, it clicked: autocomplete shouldn't live in one editor. It should work wherever you write.
So I built Cotypist. It's smart autocomplete that runs locally on your Mac (no cloud, no API calls), in basically every app you type into. Install it, give it a minute, and you're writing faster everywhere on your Mac. No long setup. Tab to accept a suggestion, keep going. Words still sound like you.
You can download Cotypist today from https://cotypist.app; there's a free 30-day trial with all the features, and there's also a free plan for casual use after that.
During early access, Cotypist has become a daily driver for founders, marketers, support folks, novelists, physicians, academics, and long-time Mac users. People who type a lot of email, Slack, and AI prompts. Plus a long tail I didn't see coming: non-native English speakers, one-handed typists, and (this still blows my mind!) not one but two Neuralink brain-implant wearers.
What still surprises me about Cotypist, even after building it, is how often it feels like it's reading your mind. Or almost like a colleague finishing your sentences.
Happy to take questions about the product, where it works (and where it doesn't), what's coming next, or anything else. I'll be here all day.
