用視覺化論文圖譜探索學術文獻
每張圖譜把種子論文放在最相關的文獻之間，並依共同被引或共享參考文獻的密度聚類。
分別展示論文所依據的基礎工作與其後的發展，非常適合追溯研究脈絡。
可從論文標題、DOI、URL 或會議論文集連結開始，用手邊已有的資訊直接進入圖譜。
當需要具體資訊而非全局概覽時，可透過排序清單依相關性瀏覽相關文獻。
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.
