A few years ago I noticed I’d developed a weird habit: I’d copy snippets of text into VS Code, just to get GitHub Copilot’s inline completions, then paste them back into the app I should have been writing in. It kept happening. Eventually I thought: there has to be a better way.
Autocomplete shouldn’t live in one editor. It should be wherever you write: email, notes, documents, messages, prompts. You start typing, see a suggestion, press Tab, keep going. And it should learn your voice across all of them, not start fresh in each one. It also had to stay on the Mac. What we type is some of the most personal information we generate.
That’s what Cotypist became.
If you’re covering it (writing, video, podcast — anything), I’m happy to send a review copy, sit down for an interview, or fact-check anything. Just reach out →
Why Cotypist is worth writing about.
The model runs on the Mac via llama.cpp, with Gemma 4 by default. No API calls, no cloud. Works offline.
Works in virtually every Mac app: Mail, Slack, Obsidian, Notion, ChatGPT, terminal AI agents. One tool, everywhere you write.
Suggests words you’d write anyway. Tab takes one word at a time so you stay in control. Don’t like a suggestion? Just keep typing. It snaps to the word you meant within a letter or two.
Cotypist picks up your vocabulary, names, and phrasing in one app and carries them to the next. Everything stays encrypted on your Mac. How it works.
More on the home page. Cotypist’s early audience includes developers, marketers, novelists, physicians, lawyers, support folks. People flipping between two or three languages a day. People who type one-handed. And (this still blows our mind) two Neuralink brain-implant wearers.
When I saw it I thought: Wow. No. I do not want that. But I continued to see everybody rave about it and so I was like, fine, fine, I’ll give it a shot. And well, everybody else was right. It’s bloody fantastic.

It’s so freakin' cool.
Cotypist has quietly become one of my must-have writing tools. It doesn’t try to replace my voice – it simply completes my sentences in a way that feels natural and helps me type much faster.

If you code-switch a lot or just want smart autocomplete that feels like it’s reading your mind (without sounding like a robot), Cotypist is absolutely worth using.
I have never learnt how to type fast before. I am a slow typist. When I started this email I had just rebooted my Mac so Cotypist was not running. I was typing this email and I thought "where is Cotypist?" as I was typing so slowly.
Once I realised Cotypist was not running and launched it, it was such a relief.
I will never go back to manual typing!!
