面向文献综述与可审计系统综述的 AI 原生研究工作台
用自然语言提出研究问题，从 PubMed、arXiv、OpenAlex、Semantic Scholar 中获取综合答案，每条结论都链接到来源论文。
按 PRISMA 流程开展综述：预定义协议、记录筛选决定、双人独立评审与冲突解决，并依据真实计数生成 PRISMA 流程图。
从 Zotero 或 Mendeley 导入、按 DOI 添加文献，自动抓取元数据与开放获取 PDF，批注与笔记可贯穿其他工作流。
自定义提取列，由 AI 批量填充多篇论文，每个数值都能回溯到原文语句，并可导出为 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.
