Cotypist
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.
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.
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 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.

I've been using for a few weeks and now I can't live without it. Highly recommend. For me, it shows how terrble Apple is with their own AI. This should be standard in the OS. Great work! I hope Apple buys Cotypist and makes you rich!
I use Cotypist to help me write my blog posts and articles, it helps me write faster and let me crank out emails so much quicker. It's great, hope others like it too!
great product! it's been helping me a lot with my writing to fix my grammar and spelling mistakes.
Awesome app. My ways of working with my laptop changed significantly after I started using it. Providing more detailed information to my colleagues and writing more detailed notes. Typo corrections even correct use of English since I'm not a native speaker. Could definitely recommend it.
One of those apps that have become an essential daily driver. “S” tier. I now get frustrated typing somewhere and not being able to tab to complete because cotypist isn’t there.
I've been using it for a few weeks, did not even know I needed something like this, but it just keeps getting better and better and it literally helps me write faster and better. I love how it can figure out the context of what I'm writing and actually write something that makes sense.
Thanks
Such an amazing app. This increases general productivity and efficiency by 10x. Easily. I strongly encourage all to install and use. I’ve using the betas since it was first introduced and it’s been stellar since day one. Daniel is a committed, responsive, and supportive developer. I’m typing this on my iPad, and immediately realized that I miss the brilliant, accurate autofill provided by Cotypist. Simply fantastic.
Congratulations on the launch! I've been using it for a few months since David Sparks (MacSparky) recommended it. Looking forward to the next stages of this brilliant app 🚀
I've been a beta tester for Cotypist for a few months, and I'm now a subscriber. It's beautifully executed and works great. The elevator pitch ("autocomplete, but with AI!" -- my words, not the dev's) really doesn't do it justice.
There are a few things about Cotypist that aren't obvious until you actually use it for a while. First, it works pretty much everywhere you can type text on your Mac. That includes browsers, editors, email clients, etc. It's always there, always unobtrusive, always seamless. Second, it’s not just super-autocomplete. It's a full-fledged AI model that runs locally on your Mac and maintains context. I work on a lot of different projects, and Cotypist is eerily good at switching around with me. It remembers things. It reads your screen (if you allow that, which I highly recommend) and adapts itself to your workflow.
It's not a writing assistant, although I suppose you can use it that way. It doesn't suggest what it thinks you should type so much as it infers what you're actually doing and tries to facilitate what you were going to type anyway.
This is the future of AI: unobtrusive, lightning-fast, and not trying too hard to take over or "help."
Been using it from a week or so and it’s been great. I love the new autocorrect feature. And the fact that it runs locally is also huge! Great product!
Cotypist has saved me a fair amount of typing in recent times. It has become especially useful now that it is able to give completions to AI agents like Claude Code in the terminal.
Congratulations on the launch!
Have you done any testing to see how Cotypist functions along with Grammarly and Wispr Flow? Also, I assume Cotypist is only available on Apple Silicon, not Intel.
One of my favorite products!!! Can't believe I've been working without it. It's on the same level as having a voice dictation app. Once you start using it, you'll never go back.
I have used this app for about half a year now, and it is simply amazing. But the price is too high, especially for me as a student. Don't get me wrong, you should absolutely charge for this. Since I use the app a lot, I would naturally want the Pro version, but as mentioned before, I just can't justify the price for myself.
I'd like to see the price go down a bit and/or a student discount, especially for the Pro version.
Been using Cotypist for a few weeks. It's impressive! I probably have on average 300+ words each day from the app in the counter of the Menu Bar. Love it.
I've been using this for a few months. Found it after I came up with idea myself, then looked to see if anyone else beat me to it - they did, and its better than I imagined. I get value from this tool every single day.
OMG. Finally. I am so glad you started charging for this product. I use this every day and have done ever since before my first video about it in December 2024. I just got a new MacBook Pro to replace my old Ollama-issued laptop and Cotypist was one of the first installs. This saves me so much time. It gets me started and keeps me going on everything I write. It's bonkers to me that some are quibbling over the price. I can only assume they never tried the product. It would be a bargain at double the cost. Congrats Daniel's on hitting this milestone.
My favorite app of 2026, unfortunately ruined by a completely unreasonable pricing model.
Love what you built, but there's no reason this should cost $108/year, especially considering that this app that runs locally on my own hardware and has no recurring costs to the developer, aside from development costs. The price tag of this single app is equivalent to the cost of almost an entire year of Setapp (hundreds of apps) or half a year of ChatGPT / Claude. The pricing tiers are also completely unjustified, with features such as per-app settings + best LOCAL model locked behind the highest tier to force users towards the most expensive option.
This would've been acceptable if it was a pay-once for one year of updates instead of a yearly subscription, perhaps with a varying price based on device count.
I went from being a happy user that was willing to pay a premium pricing and would recommend it to friends, to actively encouraging people to avoid this. If it's starting at such unreasonable prices, you can only imagine where this price is headed 1~2 years from now.
Pricing of an app should not be solely based on how much time a developer has put into it, but on the value it provides to users. Cotypist is definitely not a $108/year app, as great as it is.
