learns your voice

It gets smarter the more you use it

MacAutocomplete starts out useful and gets personal. As you write and accept suggestions, it picks up your phrasing — your greetings, your sign-offs, the product names you type all day — so completions stop sounding like a generic chatbot and start sounding like something you'd actually write. All of that learning happens on your Mac.

How it learns: your own writing, on your own Mac

There's no shared model being trained on your keystrokes, and no "send your data to improve the product" toggle hiding in Settings. The app builds a small, private profile from the text you type and the suggestions you accept, stored locally. Every time you press ⇥ Tab or →to accept a completion, that's a quiet vote: yes, that's how I'd say it. Over the first week, the model leans harder into the patterns you keep confirming and backs off the ones you keep typing past. The longer you use it, the more it sounds like you — and none of it leaves the machine.

What it picks up: voice, phrasing, and the facts you repeat

Personalization shows up in the small things you'd otherwise retype a hundred times a week:

• Your greetings and sign-offs — if every email ends with Best, Ogtay or every Slack reply opens with Hey! quick one —, it learns to offer exactly that.
• Your tone— terse and lowercase in chat, fuller and formal in email. It mirrors the register of the field you're typing in.
• Recurring facts— product names, your company's wording, the URL you paste constantly, the way you spell a teammate's name. It stops second-guessing the things you say all the time.

The result is steadier, less surprising completions: the suggestion that appears is the one you were already reaching for, which means more ⇥ Tab accepts and less correcting.

You stay in control: view it, forget it

Because the profile lives on your Mac, you can actually look at it. Open Settings → Activityto see what MacAutocomplete has picked up and how often suggestions were accepted. Don't like something it learned? Clear it. Starting a new job, changing your name, or just want a clean slate? Wipe the whole profile and it begins learning fresh from your next keystroke. There's no server-side copy to also delete, because there was never a server-side copy.

Personalization that never leaves your Mac

This is the part most "AI that learns you" tools get backwards: they personalize by shipping your writing to a cloud account. MacAutocomplete does the opposite. The local model already runs entirely on your Apple Silicon, and so does the learning — your profile is built, stored, and used in the same on-device pipeline that generates each suggestion. Nothing is uploaded, nothing trains a shared model, and nothing is logged on a server. Read the full guarantee on private & offline. Password boxes and macOS Secure Input fields are skipped entirely, so the sensitive things you type never become part of what it learns.

Where personalization pays off most is the writing you repeat daily — see it in action for email and for longer writing.
