Best for

Pick Rayyan if you are running a formal systematic or scoping review and need PRISMA-compliant screening with team workflows and AI-assisted prioritization.

Skip if

Skip it if you want a general-purpose chat-with-your-PDFs RAG tool or a self-hosted, open-source alternative.

Rayyan is a cloud platform built specifically for systematic and literature reviews, the kind of multi-thousand-paper screening exercises that dominate evidence-based medicine, health policy, and meta-analytic research. It handles the full pipeline: importing references, deduplicating up to 200,000 records, title/abstract screening with AI prioritization, full-text eligibility checks, structured data extraction, risk-of-bias assessment, and auto-generated PRISMA flow diagrams. A mobile app supports offline screening, and team workflows include role assignment and workload sampling for blinded multi-reviewer projects.

The differentiator is domain specificity. Rayyan isn't a generic RAG tool repurposed for academia, it was purpose-built with the Cochrane/Campbell systematic-review crowd in mind and now claims over a million researchers across 20,000+ institutions. The newer ResearchPilot tier adds zero-shot relevance ratings, an AI Analyzer, an AI Reviewer, and Auto-Extract Data, pushing into territory that historically required a graduate student-month of manual labor. Pricing is freemium: a permanent free tier for individual basic use, with enterprise plans for institutions and pharma/biotech sponsors negotiated via sales.

An API exists for programmatic integration, useful for institutional librarians wiring Rayyan into wider research-ops stacks. The product is proprietary SaaS, not open source, and its AI assist is screening-oriented rather than a general-purpose retrieval interface, so teams looking for a build-your-own RAG over papers will find this opinionated.

Editor's take

Rayyan is the default for serious systematic reviewers for a reason: deep domain fit, large-scale dedup, and an AI assist that actually targets the bottleneck (title/abstract screening). The ResearchPilot additions push it toward genuine automation, though institutions should price the enterprise tier before committing.
