You know the sentence before you finish typing it. Your brain got there three words ago. But your fingers are still catching up — letter by letter, in your email, your Slack reply, the comment you're leaving on a PR.
That gap between knowing and typing is where most of your day quietly leaks away.
AI was supposed to fix this. Instead it gave us a chat box in another window. Stop what you're writing, switch apps, write a prompt explaining what you want, wait, copy the answer back, then rewrite it so it sounds like you. That's not faster. That's a detour.
We built TypeTab because we wanted the opposite of a detour.
TypeTab 1.0.0 is on-device autocomplete for your whole Mac. It finishes your sentences inline, right where your cursor already is, in every app you type in — Mail, Messages, Slack, Notion, your browser, docs. Ghost text appears as you write. Press Tab to take the next word, Ctrl+E to take the whole line, or just keep typing to ignore it. Every prediction runs on Apple Silicon. Nothing ever leaves your Mac. $49 once — 50% off at launch.
The Problem Was the Keyboard
We spend our day writing. Not novels — the thousand small texts that a builder studio runs on. Standup updates in Vext-dictated bursts, PR descriptions, customer replies, the Slack thread that decides the week. Prompts to Octomind agents and Claude Code, all day long.
And every one of them shares the same bottleneck: the keyboard. Your thoughts arrive at the speed of thought. Your fingers arrive at the speed of fingers. The whole point of Timex, our time tracker, is to show you where the day went — and an uncomfortable amount of it goes to typing things you already knew you were going to type.
So we tried the existing tools.
ChatGPT and the chatbot crowd are a different shape of work. They're a destination — you leave what you're doing, go ask, and come back with text that sounds like a chatbot, not you. Great for drafting from scratch. Useless for finishing the sentence you're already in the middle of.
Grammarly corrects you after the fact and lives in the cloud. It's a proofreader, not a co-writer, and your text goes to their servers to get it.
Compose AI and the browser extensions only work in the browser, only with an account, and only after your keystrokes have made a round trip to someone else's machine.
Apple's predictive text is on-device and free — but it tops out at the next word in a handful of fields, never learns your voice, and never finishes a line.
What we wanted was simpler than all of them: the right next words, already there, in every app, without anything leaving the Mac.
Three Keys Is the Whole Interface
There's nothing to learn. If you can type, you already know how to use TypeTab.
Tab — take the next word. Suggestions appear inline as faint ghost text. Press Tab and the next word lands. Stay in your rhythm, accept one word at a time, keep your judgment in the loop.
Ctrl+E — take the whole line. When the suggestion is right and you can see it's right, grab the entire line in a single keystroke. The words are there the moment you would have typed them.
Keep typing — ignore it. Don't like a suggestion? Type right over it. No popup to dismiss, no menu, no mode to exit. TypeTab updates as you go and never gets in your way.
That's the entire interface. No settings to learn, no per-app setup, no wizard. It lives in your menu bar and stays out of your dock.
Works Everywhere You Already Type
TypeTab isn't a browser extension or a single editor plugin. It's one system-wide tool that works in almost every native text field on macOS — Mail, Messages, Slack, Notion, Google Docs, X, WhatsApp, Notes, your browser, your terminal. There's no per-app configuration because there's nothing to configure. Install it once and it's everywhere.
It fixes typos inline, too. TypeTab quietly catches the slips as you type and offers the correction in the same ghost text — Tab to apply, or keep going. No red squiggles to right-click, no after-the-fact pass.
It learns your style. TypeTab picks up your vocabulary, your names, your phrasing over time. The suggestions start to sound like you — not a model, not a committee. You only ever accept what fits, so the words stay yours. We believe in augmenting your writing, not replacing it.
It speaks your languages. TypeTab works across many languages and is especially good for non-native English writers and mixed-language typing — it meets you wherever your words come from.
The Architecture of "On Your Mac"
Every cloud writing tool we evaluated sends your keystrokes somewhere. Grammarly uploads your text. Compose AI round-trips through their backend. The chatbots log everything you paste.
TypeTab does none of that.
Every prediction runs on the Apple Neural Engine, on your Mac. Your words, your documents, your messages are never uploaded, never logged, and never used to train a model. There's no account to create because there's nothing to store on our end. Block the app with Little Snitch and it doesn't notice. It works fully offline — on a plane, at a café, anywhere.
This isn't a privacy policy we wrote. It's the architecture. There's nothing to phone home with.
That's the whole reason we could build it for every app and mean it. Your keyboard touches your work email, your personal messages, that tricky reply you're agonizing over, and everything in between. A tool that lives in your keyboard has no business sending any of it away. So TypeTab doesn't.
Skip the Prompting Tax
Here's the chatbot workflow, honestly:
- Stop what you're writing
- Switch to a chatbot in another window
- Type a prompt explaining what you want
- Wait for it to think
- Copy the answer back
- Rewrite it so it sounds like you
Here's the TypeTab workflow:
- Keep typing
- Press Tab
That's it. The suggestion is already in the sentence you're writing, in your voice, on your Mac. There's no context to re-explain because TypeTab is reading the field you're already in. The "prompting tax" — the stop, the switch, the wait, the cleanup — just disappears.

$49, one-time. Three Macs. No tiers, no "pro" plan that unlocks limits you didn't know existed. Right now it's 50% off.
The trial is the part we're proud of: 100 word completions and 20 full-line completions for free — no card, no account. Enough to feel whether it fits before you pay a cent. After that, $49 one-time unlocks unlimited completions on up to 3 Macs (50% off with TYPETAB50 through July 1, so $24.50 right now). Free updates within this major version. Major v2 will probably be a paid upgrade; v1 keeps working forever.
We don't run a server. There are no cloud bills to pass on, no recurring revenue we need to keep a Mac app alive. Charging a subscription for a tool that runs entirely on your own computer felt dishonest. So we charge once.
How We Use It
We've been running TypeTab internally for weeks. Here's where it shows up.
The reply you've written a hundred times. "Thanks for flagging this — I'll take a look and get back to you by..." You don't type it anymore. Tab, Tab, Ctrl+E. Done. The boilerplate of work email evaporates.
PR descriptions and commit messages. The summary is in your head; TypeTab gets it onto the line. Pair it with Vext when you'd rather talk it through — dictate the gist, then let TypeTab finish the cleanup as you tighten it up.
Prompts to agents. Writing a prompt to an Octomind agent or Claude Code is itself typing. TypeTab finishes the predictable scaffolding — "refactor the X module so that..." — and you fill in the part only you know.
Long messages on tired hands. End of a long day, wrists complaining, inbox full. Half the keystrokes means half the strain. This was the surprise: TypeTab isn't just faster, it's gentler.
Made for How You Write
TypeTab isn't only for power users. It quietly helps anyone who types — which is everyone.
- Non-native writers — write with confidence in your second or third language; TypeTab fills the gaps.
- Fast thinkers — when your brain outruns your fingers, TypeTab catches the rest of the sentence.
- Tired hands — fewer keystrokes, less strain, gentler on long writing days.
- Inbox warriors — blast through email and replies in a fraction of the taps.
What's Coming
TypeTab 1.0.0 ships today. Here's what's already on the board:
- Smarter, larger on-device models for sharper suggestions on capable Macs
- Per-app tone (more formal in Mail, looser in Messages)
- Snippet expansion for the phrases you type constantly
- Deeper Muvon ecosystem links — shared local context with Vext and decision memory via Octobrain
What's not changing: on-device, no cloud, no telemetry, one-time price.
FAQ
What is TypeTab?
TypeTab is on-device autocomplete for Mac that runs entirely on your machine. It finishes your sentences inline in any app — Tab takes the next word, Ctrl+E takes the whole line, keep typing to ignore. No cloud, no account, no subscription. $49 once.
How is TypeTab different from ChatGPT?
TypeTab is not a chat box. It finishes your sentences inline, right where your cursor is, in any Mac app — no prompting, no switching windows, no copy-paste. You stay in your flow and press Tab when a suggestion is right.
Does my text leave my Mac?
No. Every prediction runs on-device on Apple Silicon. Your words, documents, and messages never leave your Mac, are never uploaded, and are never used to train any model. TypeTab works fully offline.
Which apps does it work in?
Almost all of them — Mail, Messages, Slack, Notion, your browser, docs, and most native text fields. It's one system-wide tool, so there's no per-app setup.
Will it make my writing sound generic?
No. TypeTab suggests your next words, not a chatbot's. It learns your vocabulary and tone, and you accept only what fits — so the words stay yours.
Does it support languages other than English?
Yes. TypeTab works across many languages and is especially helpful for non-native English writers, mixed-language typing, and anyone who finds typing physically tiring.
Which Macs does it support?
macOS 14 (Sonoma) or later on an Apple Silicon Mac (M1 or newer). 16 GB of memory is recommended for the smoothest experience. No account required.
Will it drain my battery?
TypeTab runs lean on the Apple Neural Engine and only computes while you're actively typing. On a recommended Mac the impact on battery life is minimal.
Why one-time pricing?
Because we don't have server costs to amortize. The app runs on your Mac. There's nothing to host. Recurring revenue for a tool that runs entirely on someone else's computer felt dishonest, so we don't do it.
