依研究設計、樣本數、期刊品質、發表年份等條件過濾結果,優先呈現高品質證據。
將大量研究的結果彙整為結構化摘要,勾勒已知結論與尚存空白。

MemFree is a hybrid AI search engine that answers questions by combining live internet results with your own uploaded knowledge base. It also summarizes pages, searches Twitter, explains code and generates shareable answer pages, aiming to return accurate answers faster.
Combines live internet search with a personal knowledge base so answers draw on both public sources and your own documents.
Search, compare and summarize multiple images, and generate pages that pull in visual results alongside text.
Upload documents to build a knowledge base you can query directly for grounded answers to your own material.
Read, explain and even write code, making it useful for quickly understanding unfamiliar snippets.

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.
