honest comparison
MacAutocomplete vs Apple predictive text
Your Mac already finishes the odd word for you. So why add another tool? Because Apple predictive text and MacAutocomplete are doing two different jobs — one guesses the next word, the other writes the rest of your sentence.

What Apple predictive text actually does
Apple's built-in suggestions are word-level. As you type, macOS offers the most likely next word or two based on a small on-device dictionary and recent usage. It's fast and private, but it works one word at a time, has little sense of the surrounding sentence, and only shows up in a subset of system text fields. It was never built to draft prose — it's a typing accelerator, not a writing assistant.
What MacAutocomplete does instead
MacAutocomplete reads the text around your cursor and predicts the whole rest of the sentence with a local language model running on your Apple Silicon Mac. The suggestion appears inline as greyed ghost text:
Following up on yesterday's thread — I've attached the updated figures and flagged the two items that still need sign-off.
Press ⇥ Tab or → to accept the whole thing. Keep typing to ignore it. Because it hooks the system text layer, it works in nearly every standard field — not just the handful of apps Apple covers.
Side by side
| Apple predictive text | MacAutocomplete | |
|---|---|---|
| Prediction length | Next word or two | Rest of the sentence |
| Context awareness | Word-level, limited | Reads prefix + suffix around the caret |
| Engine | Dictionary / small model | Local LLM (MLX, on-device) |
| App coverage | Some apps | Most standard text fields, system-wide |
| Runs offline | Yes | Yes — zero outbound network |
| Cost | Built in | $125 once, 3 Macs, free updates |
They're both private — that part is genuinely equal
Credit where it's due: Apple's predictive text is on-device and offline, and so is MacAutocomplete. Every completion is computed on your Mac and nothing you type leaves it — you can confirm there's no outbound traffic with a tool like Little Snitch. Password and secure-input fields are never read. The difference isn't privacy; it's how much MacAutocomplete can write for you and where it shows up. See exactly how it stays local and private, and where it works across every app.
Use both, honestly
You don't have to turn Apple's suggestions off. They sit at a different layer and rarely conflict. Apple finishes a word; MacAutocomplete finishes the thought. If you write real sentences all day — email, Slack, Notes, Messages — the sentence-level draft is the part that saves you minutes, not milliseconds. The honest caveat: canvas editors like Google Docs and Sheets, some GPU editors, and games don't expose a readable text field, so MacAutocomplete stays quiet there.
Frequently asked questions
Is MacAutocomplete better than Apple predictive text?
They aren't quite the same job. Apple predictive text suggests the next word or two from a small on-device dictionary; MacAutocomplete uses a local LLM to draft the rest of your sentence as inline ghost text you accept with ⇥ Tab or →. If you write full sentences all day, the sentence-level completion is the bigger time-saver — and it shows up in far more apps. Both are on-device and offline, so neither beats the other on privacy.
Does Apple have a system-wide AI autocomplete on Mac?
Not in the same sense. Apple's predictive text is word-level and only appears in a subset of system text fields, and Apple Intelligence writing tools rewrite a selection you invoke rather than predicting inline as you type. MacAutocomplete is a system-wide, sentence-level autocomplete: because it hooks the macOS text layer, it works in Mail, Slack, Notes, Messages, and most browsers and chat apps. The honest exceptions are canvas editors like Google Docs, where no readable text field is exposed.
Does MacAutocomplete replace Apple predictive text?
No — you can run both. They sit at different layers and rarely conflict: Apple finishes a word while MacAutocomplete finishes the thought. There's no need to disable Apple's suggestions, though many people stop noticing them once the sentence-level ghost text is doing the heavy lifting.
Is MacAutocomplete private like Apple predictive text?
Yes. Every completion runs on your Apple Silicon Mac with a local MLX model, with zero outbound network — you can verify there's no traffic using a tool like Little Snitch. Password and secure-input fields are never read. It requires macOS 14.2+ and costs $125 once for 3 Macs, with no subscription.
