Typeahead vs Grammarly: two different jobs.
Grammarly checks what you’ve written. Typeahead suggests the rest of your sentence while you write it, on your Mac.
The short answer.
Choose Grammarly if…
- You want grammar and spelling checked.
- You want feedback on your tone.
- You also write on Windows.
Choose Typeahead if…
- You want the rest of each sentence suggested as you type.
- You want suggestions made on your Mac, not on a server.
- You want it working offline after setup.
Or keep both: Typeahead while you write, Grammarly when you check.
After you write, or as you write.
The same email, two ways: checked once it’s written, or finished as you type.
GrammarlyAfter you writeGrammarly in Outlook: you type the whole line, “Thanks for the agenda, it looks great. See you on Thrusday.” Once it’s written, Grammarly underlines “Thrusday”, shows a card suggesting “Thursday”, and the fix is taken.
TypeaheadAs you type
Typeahead in Outlook: you type “Thanks for the agenda, it looks great. See you” and Typeahead suggests “on Thursday.” in grey at your cursor. Tab takes it.

Common questions
Grammarly checks and rewrites what you’ve written, and drafts when you ask. Typeahead suggests the rest of your sentence while you’re still writing it, in grey at your cursor, and Tab takes it. It reads the window you’re typing in, so a reply picks up what was just said, and every suggestion comes from an AI model on your Mac.
Not anymore. Grammarly’s help center says autocomplete has been deprecated in its browser extension. Its newer Go assistant underlines your text and offers edits while you type; it doesn’t continue your sentence. Typeahead is built around exactly that: the rest of your sentence, in grey, in Mac apps with a standard text field. Tab takes it, or keep typing and it follows you.
It depends on what you use Grammarly for. For grammar and spelling, no: Typeahead suggests how your sentence goes on and doesn’t proofread, so keep Grammarly for that. For getting words down faster, yes: Typeahead finishes your sentences as you type, in the writing style you set for each app, and learns the lines you write often.
No. Grammarly’s help center says it’s an online application, so your computer must be connected to the internet for it to check your text. Typeahead’s suggestions come from a model on your Mac, so it works offline after setup. A plan checks your license when you’re back online.
That’s your compliance team’s call, but here is what each one documents. Grammarly checks your text online, and for individual accounts its help center says Product Improvement and Training is on by default (you can switch it off). Typeahead never sends your writing to a server. It goes online only to check your license, look for updates and download your AI model, and none of those requests include anything you write.
They do different jobs: Typeahead suggests while you type, and Grammarly reviews what you wrote. We haven’t tested them side by side yet, so if they get in each other’s way, the 30-day money-back guarantee covers you. You can also turn Typeahead off for one app from the menu bar.
Typeahead is a Mac app, for macOS 14 or later. It works in text fields in the major Mac browsers with no extension to install; Google Docs and Arc need a one-time setup. Grammarly also has a Windows app and browser extensions for Chrome, Safari, Firefox and Edge.
