Best Mac autocomplete apps (2026)

“Autocomplete” covers two very different jobs on the Mac: tools that predict the rest of your sentence as you write, and tools that expand shortcuts into canned text. Here is an honest look at the best of both in 2026 — what each one does and who it's for.

1. MacAutocomplete — our pick for everyday writing

MacAutocomplete predicts whole sentences inline, in any standard text field. You type and a greyed ghost completion appears at your cursor:

Thanks for the update — I'll review it and get back to you tomorrow.

Press ⇥ Tab or →to accept, or keep typing to ignore it. The model runs locally on Apple Silicon, so it's fully offline — nothing you type leaves the Mac, and you can verify zero outbound traffic with Little Snitch. It's $125 once, lifetime, 3 Macs, no subscription. Best for anyone who writes all day in Mail, Slack, Notes, and Messages and wants prediction in every app without a recurring bill.

2. Cotypist — popular, subscription

Cotypist is the best-known on-device autocomplete for Mac and a genuinely good tool. It predicts inline completions locally, much like MacAutocomplete. The catch is the business model: it's closed-source and moving toward freemium and subscription tiers. Best for people who don't mind a recurring fee and want the most established name — though if you want to buy once and own it, see our Cotypist alternative.

3. Cotabby & KeyType — open-source clones

Cotabby and KeyType are open-source autocomplete projects that take the same on-device, tab-to-accept approach. Being open source, they're free and inspectable, which appeals to tinkerers. The trade-off is the usual one with community projects: setup, model management, and polish are on you, and support depends on whoever's maintaining the repo. Best for developers comfortable building from source who value transparency over a turnkey experience.

4. TextExpander & Text Blaze — snippet expanders

TextExpander and Text Blaze (and Raycast's snippet feature) are a different job entirely: you define a shortcut like ;addrand it expands into a saved block of text. They don't predict prose — they replay text you wrote earlier. That makes them excellent for repeated boilerplate: support replies, email signatures, legal clauses. Best for people who send the same exact text over and over, rather than writing something new each time.

5. Apple predictive text — built-in, basic

macOS ships with predictive text that suggests the next word or two as you type. It's free, on-device, and already there. But it's word-level, not sentence-level, and only appears in some apps. Best as a zero-effort baseline — if you only want the occasional word finished and don't want to install anything.

At a glance

Honest note: every predictor here, including ours, stays quiet where there's no readable text field — Google Docs and Sheets paint onto a canvas, as do some GPU/canvas editors and games. MacAutocomplete needs Apple Silicon and macOS 14.2+.

Which should you pick?

If you want sentence-level prediction everywhere, fully local, with no subscription, that's exactly the gap MacAutocomplete fills. If you mostly resend identical text, a snippet expander is the right tool. And if you just want the next word once in a while, Apple's built-in predictive text already does that for free.
