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。
一鍵找出相似學術論文，由 AI 搜尋驅動
在任何論文頁面點擊擴充功能，即可取得概念相關的論文排序清單，無需重新輸入檢索詞。
結果來自 Exa AI 搜尋引擎，按含義與上下文排序，而非精確關鍵字比對。
檢索透過 Exa API 完成，因此 Dewey 不綁定單一文獻庫，可作用於出版商頁面、預印本網站與個人首頁。
擴充功能安裝檔體積極小且不顯示廣告，幾乎不增加頁面載入與介面負擔。

Semantic Scholar is a free, non-commercial academic search engine built by the Allen Institute for AI (Ai2). It indexes more than 240 million papers from every field of science and uses machine learning to extract meaning from abstracts, citations, figures and tables, so researchers find relevant work faster than with keyword-only search.
