依程式碼與系統自動生成的 AI 架構圖與技術設計文件
依文字提示、程式碼、Terraform 或上傳的 PDF、Word、Excel、PowerPoint、Draw.io、Visio 檔案，產生架構圖、流程圖、時序圖與 BPMN。
建立可與雲端帳號、程式碼倉庫和內部目錄同步的互動式地圖，支援從組織層級下鑽到單一容器，讓畫面貼近真實環境。
貼上程式碼或連接私有／公開 Git 倉庫、Confluence、Notion、VS Code 與 GitHub，讓圖表始終立基於真實實作。
可在自有基礎架構中以 MIT 授權執行工具包，讓相容 MCP 的用戶端透過 OAuth 或 API 權杖建立、檢索、更新與匯出圖表。
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.
