Cotypist predicts your next words in every Mac app — on your Mac, not in the cloud. Press Tab to accept. Eerily good at picking up on what you're about to write.
Free to download for Apple Silicon — 30-day Pro trial, then a free plan. No credit card required.
Still your words. Just faster.
Drag the Mac app into Applications. It runs locally on Apple Silicon and takes only a few minutes to set up, no account required.
Open any Mac app and write the way you always do. Cotypist predicts the rest of each sentence.
Don't like a suggestion? Just keep typing. It'll snap to the word you meant within a letter or two.
Press ⇥ to take the next word or the whole line.
The more you write, the better Cotypist gets at sounding like you. It picks up your vocabulary, your names, and the way you phrase things.
Why dancing with the AI feels better than delegating to it.
We've all been there:
You stop writing. You open a chatbot. You write a prompt. You wait.
You get a robotic wall of text.
You spend ten minutes editing it to sound like you.
Frustrated, you trash it and just write the damn thing yourself.
You never leave your flow.
You start typing, and the right words just appear—your words, the ones you would have written anyway.
No more wrestling to get the thoughts out of your head.
Tab. Flow. Smile.
What felt like work now feels like flying.
We believe in augmenting your writing,
not replacing it.
Cotypist suggests words you'd write anyway—just faster.
Your work, written with AI — not by AI.
Suggestions appear inline, in whatever app you're already in. Tab takes the next word; keep typing if you don't want it. After a few minutes you barely notice it's there.
Cotypist picks up on your style fast. Cut your typing roughly in half, without losing your voice.
All processing happens on your Mac. No prompts ending up in someone else’s training data. The kind of privacy you’d want from your keyboard.
Apple Mail, Slack, Notion, Obsidian, your favourite browser, and most other Mac text fields. Same tool everywhere, no per-app setup.
No more flipping to ChatGPT, prompting, waiting, editing. Cotypist suggests your next words right in the app you’re already in.
Suggestions land without perceptible delay. It feels like skipping the step between thinking a word and typing it.
Don’t like a suggestion? Just keep typing: Cotypist usually updates to the word you actually wanted within a letter or two.
Stuck on the next word? Cotypist always has one. Even rejecting the suggestion is usually enough to get moving again.
Partial match? Accept suggestions word-by-word. Switch between AI assistance and your own writing at any time, even mid-sentence.
Cotypist spots typos in the word you’re typing and offers the fix inline. Tab to apply; no pop-ups, no red squiggles to clean up later.
Type a colon and the right emoji appears. Filter by typing a shortcode, no need to scroll the picker.
Cotypist works for non-native English writers, dyslexic typists, people with hand arthritis, one-handed typists, and (yes, really) Neuralink implant wearers.
Email, Slack, support replies, AI prompts, your novel — this is where the keystrokes really stack up.
Zip through your inbox. Craft thoughtful replies in half the time.
Faster prompts for ChatGPT, Claude, and coding agents. Cotypist even helps you find the right words to prompt your other AI tools.
Cotypist learns your campaign voice as you go. Less time staring at the blinking cursor; more drafts out the door.
Post more in your own voice. Cotypist doesn’t try to write for you, it just finishes the sentence you’d have typed.
Fewer words per reply, ticket after ticket. The time savings add up fast.
Docs are repetitive by design — which is exactly where Cotypist’s predictions land hardest.
Levels the playing field for non-native speakers, dyslexic writers, and people who type with one hand. (Yes, it works in Norwegian. And Hinglish.)
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.
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!!
I’ve been using Cotypist on macOS. Sometimes it feels like it’s reading my mind when I’m typing.
I really enjoy using Cotypist already. I think this is one of the best AI tools that help me be more productive every day.
I just love how it integrates everywhere I type so seamlessly. I almost forgot how it was before that.
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.
As someone who writes for a living (not creative, but repetitive technical type stuff) Cotypist has been a lifesaver.
I think it will literally save my wrists from carpal tunnel.
Cotypist enhances your writing style without replacing it. It offers suggestions based on your input, but you always decide what to use. Your unique voice remains intact as you choose which suggestions to keep or discard. If a suggestion doesn’t fit, just keep typing and Cotypist will adapt.
Often, only part of a suggestion is useful. That’s why Tab inserts just the next word from a suggestion — press it repeatedly to accept only the part you want, then keep typing until Cotypist’s suggestions align with your intent again.
There might be a slight learning curve as you start paying attention to completions, but most users quickly find it becomes second nature.
Cotypist can be remarkably accurate, especially with longer texts where it has more context. It sometimes even feels uncanny.
But it’s not perfect - your expertise and creativity are still crucial. After all, if it could replace all your writing, you could get replaced by a robot!
Cotypist excels with thoughtful writing rather than quick chats or messages.
Cotypist isn’t meant to replace ChatGPT or handle complex tasks. Instead, it’s designed to continuously save you time throughout your day by suggesting words you would have typed anyway.
Unlike ChatGPT, Cotypist works seamlessly in all your apps, doesn’t require crafting prompts, and keeps you in full control of your writing. It’s about enhancing your productivity, not replacing your creativity.
Cotypist works with most Mac apps out of the box, including Safari, Chrome, Apple Mail, Word, Apple Notes, Notion, Obsidian, Messages, and many more.
A few apps need a small setup step — for example, Google Docs requires enabling Accessibility mode, and Arc/Dia need a browser setting toggled for inline suggestions.
In code editors like VS Code and Cursor, Cotypist works in sidebar chats (for AI coding assistants) but not in the main editor, where tools like Copilot are better suited. In terminals, Cotypist activates automatically when it detects you’re typing in an AI agent’s prompt.
See the full compatibility list for details and setup instructions.
Cotypist works on any Apple Silicon Mac running macOS 14 or later. Intel Macs are not supported.
For the best experience, we recommend an M1 Pro or M2 (or higher) with 16 GB of system memory. The more powerful your machine, the smoother the experience.
While active, Cotypist uses about 1-2.5 GB of system memory, but it’s designed to run efficiently and won’t slow down your Mac. You can work seamlessly with your other apps while Cotypist enhances your typing speed in the background.
On systems with the recommended specs, completions should appear almost instantly. This allows you to maintain your writing flow without interruptions.
Cotypist’s powerful AI can be energy-intensive. But by helping you work faster, you might still get more done on a single charge. We’re constantly optimizing for better performance and energy efficiency.
Your privacy is paramount. All processing happens locally on your Mac. Your words and data never leave your device, ensuring the confidentiality of your work. macOS automatically protects password fields from being read by Cotypist.
This local processing is not only more private, but it’s also better for the environment than running a large language model in the cloud. For details on what Cotypist can and cannot see, check the privacy overview.
You do. Cotypist does not claim any copyright or ownership over texts you write with its assistance. We see Cotypist as a writing tool — much like a spell checker, Grammarly, or Photoshop — that helps you create, but doesn’t own what you create. The words are yours.
That said, we’re not lawyers, and copyright law around AI-assisted content is still evolving. If copyright ownership is critical for your work, we recommend consulting a legal professional for advice specific to your situation.
While Cotypist performs best with English, it also supports many other languages. We encourage you to try it with your preferred language and see how it works for you.
Cotypist has a free tier — full suggestions through your first 100 completed words a day, plenty for casual use. Heavier writers can subscribe to Plus or Pro for unlimited completions and more, and every install starts with a 30-day Pro trial (no credit card required).
