手寫筆記、PDF 註記與 AI 學習工具，都在同一塊畫布上
低延遲墨跡、防誤觸手掌辨識、劃掉即擦除以及手寫轉文字，讓書寫接近紙筆手感。
匯入合約、論文或教材，用手直接標註，註記可搜尋並可乾淨匯出。
同時檢索鍵入文字、手寫與速寫，並把筆記轉成摘要、心智圖或結構化計畫。
在共享筆記本、文件和白板上同時協作，不再有版本衝突或反覆傳檔案。
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.
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.
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.
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.
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.
