以 AI 驅動的科學知識視覺化探索引擎
每次搜尋都會生成一張互動式概念地圖,把相關科研產出歸入帶標籤的可點擊聚類,而不是單一平鋪清單。
透過 BASE 聚合器檢索來自 11,000 多個來源、覆蓋 400 多種語言的 4 億多筆紀錄。
除期刊論文外,結果還涵蓋資料集、軟體、圖像等研究物件,讓你看到更完整的主題面貌。
地圖由元資料生成而非合成文字,因此你看到的內容都對應真實被索引的紀錄。
為文獻回顧與可稽核系統性回顧打造的 AI 原生研究工作台
以自然語言提出研究問題,從 PubMed、arXiv、OpenAlex、Semantic Scholar 取得綜合答案,每項結論都連結到來源論文。
依 PRISMA 流程進行回顧:預先定義協議、記錄篩選決定、雙人獨立評閱與衝突解決,並依真實計數生成 PRISMA 流程圖。
從 Zotero 或 Mendeley 匯入、依 DOI 加入文獻,自動抓取中介資料與開放取用 PDF,註記與筆記可貫穿其他流程。
自訂萃取欄位,由 AI 批次填入多篇論文,每個數值都能回溯原文語句,並可匯出 CSV 或 Excel。

免費 / 開源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.

Metaso AI (秘塔AI搜索) is a Chinese AI search engine that returns synthesized, source-backed answers instead of an ad-filled list of links. It searches the open web, document libraries, and academic literature, then organizes results into structured reports with citations you can trace.
