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。
Rayyan is an AI-assisted systematic review platform that helps research teams import, deduplicate, screen, extract data from, and report on literature across the full evidence synthesis workflow.
The Systematic Auto-Resolver deduplicates up to 200,000 references using your own inclusion and exclusion protocol with one click.
ResearchPilot delivers zero-shot relevance ratings, an AI Analyzer, an AI Reviewer, and auto-extraction to speed up search, screening, and data capture.
Work through title, abstract, and full-text screening with inclusion and exclusion tagging, conflict resolution, and blinded reviewer modes.
Capture structured study data with configurable extraction fields, apply PICO frameworks, and export results with auto-generated PRISMA diagrams.
免費 / 開源Provides a completely free and open academic search database, but lacks collaborative literature review screening tools.
