Frequently Asked Questions: Grammarly vs Typeahead
Grammarly has 58,867,412 monthly visits, while Typeahead has 10,384. Traffic estimates describe audience size, not product quality.
Consolidating Premium and Business into Grammarly Pro ($12/member/month annual) gives individuals and small teams access to style guides, analytics, and plagiarism/AI detection in one plan.

Limitations
–Month-to-month billing on Grammarly Pro is steep at $30/member/month compared to the $12/member/month annual commitment ($144 billed upfront).
–Core writing intelligence and style rules remain primarily optimized for English dialects (US, UK, Canadian, Australian, Indian) rather than native multilingual grammar checking.
–Aggressive inline underlines and pop-up agent cards can feel visually intrusive in dense technical documents or code-heavy web editors unless muted per domain.
Typeahead
AI autocomplete for your entire Mac, running locally and never sending your writing to a server
Sentence completion where you already type
Faint ghost text completes the word or sentence you are typing right at the cursor. Tab accepts the entire suggestion, the right arrow takes just the next word, and Esc dismisses it so you stay in control.
Private by design and offline capable
The model runs on your Mac rather than in the cloud. Typeahead never sends your writing to a server and keeps working offline after setup, which makes it suitable for work email and sensitive documents.
Screen and clipboard context
It reads what is on screen and what you copied to the clipboard, so replies fit the thread you are actually answering rather than being generic filler.
Per-app writing styles and your own colour
Set a voice per app, professional in Mail and friendly in Messages, choose from seven color-blind-safe highlight shades, and tune suggestion timing to instant, balanced or only when you pause.
Strengths & Pros
+Completes your sentences in place, so you never leave the app you are writing in or copy text back from a chatbot
+Runs locally on your Mac and never sends your writing to a server, with offline support after setup
+Learns your own phrases and personal vocabulary, so suggestions sound like you rather than like a generic model
+Screen and clipboard context make replies fit the actual thread or document
+Per-app writing styles, 16 languages, adjustable timing and seven color-blind-safe highlight colours give fine-grained control
+Works across a wide set of everyday Mac apps including Mail, Messages, Slack, Notion, Chrome, Gmail, Outlook, Google Docs and Word
Limitations
–Currently Mac-only, so Windows, Linux, iOS and Android users cannot use it
–The site still shows a waitlist alongside 'Get Typeahead', which can suggest availability is being rolled out gradually
–Because it only completes text where you already type, it will not draft a long document or research a topic for you the way a chat assistant will
–Per-app writing styles and learned phrases take a little setup before the suggestions feel genuinely personal
–Payment structure is described only as paid, without an obvious free tier for long-term use
