SpellType 和 Typeahead 的最佳替代方案 (共 12 个)

Typeahead

Typeahead is a system-wide AI autocomplete app for Mac that completes your sentences inside the apps you already use, running entirely on your machine so your writing is never sent 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.

优势与优点

+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

局限性

–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
