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。
依素材自動產生單字卡與簡報,並使用內建 AI 寫作與 AI 偵測功能來起草與檢查學術文本。

David is a small Chrome extension that fills in web forms for you. It reads the fields on a registration, survey or checkout page and populates them using what it has learned about your preferences, so repetitive data entry takes seconds instead of minutes.
Detects form fields on the page and populates them automatically rather than making you tab through and type each one.
The extension adapts to your preferences and typical answers, so repeated fills need less correction.
Settings let you decide how much the extension does on its own versus how much you review before submitting.
Covers registrations, surveys, checkouts and other multi-field web forms rather than one specific site.
