Rayyan

What it does

Rayyan takes in bibliographic references from research databases and reference files, then guides a team through deduplication, title and abstract screening, full-text screening, data extraction, risk-of-bias assessment and reporting. Outputs include screened study sets, extracted data, exported results and auto-generated PRISMA flow diagrams ready for publication.

Researchers use Rayyan to split screening work among collaborators, track decisions with a visible audit trail, and resolve conflicts between reviewers. Features named on the site include an auto-resolver for duplicates, programmable keyboard shortcuts, a mobile app, data sampling for randomized subsets, and ResearchPilot AI tools such as zero-shot relevance ratings and an AI reviewer.

Rayyan suits individual researchers, small research groups, academic institutions and enterprise teams conducting systematic reviews. A free plan is available with limits on active reviews and reviewers, while paid plans add PRISMA diagrams, more reviewers and AI features. Limits include restricted mobile access on the free plan, and reviewer and review caps that vary by plan.

What it can do

• Import and organize references from multiple sources
• Deduplicate references with an auto-resolver using a custom protocol
• Title, abstract and full-text screening with inclusion and exclusion labels

• Generate PRISMA flow diagrams and export results

Before you choose

• Free plan limits active reviews, reviewers and samples; higher plans are needed for larger teams.
• Mobile app access is limited on the free plan and unlimited on paid plans.
• ResearchPilot AI features and some risk-of-bias criteria are marked as new and may depend on plan.
