Beam is a native ChatGPT client for macOS that lets you summon an AI assistant from anywhere on your desktop with a single hotkey, without leaving the app you are working in.
Hit a global hotkey to open a floating chat panel over any app, ask a question, and drop the answer back into your document or field without switching windows.
Select a text snippet, chat about it, and insert the improved version back into your app with a single keystroke.
Grab a screen region with a hotkey and ask ChatGPT to explain, transcribe, or describe what is shown in it.
Save frequently used prompts as reusable templates with blank fields, so repetitive writing tasks like emails or blog drafts take seconds.
與任何 PDF、影片或網頁對話，幾秒內取得附引用的答案
每則回答都錨定來源文件，附可點擊引用並自動捲動至特定段落，核對只要幾秒，不必逐頁翻找。
將文件歸入資料夾，在同一個對話中查詢多個檔案，方便比較論點、交互核對結論或一次複習整門課程。
把冗長的論文、報告與合約濃縮成重點，也支援以任何語言翻譯或提問——甚至可用一種語言上傳、另一種語言提問。
