Rayyan

Rayyan is an AI-powered systematic review and literature review platform designed to accelerate evidence synthesis for researchers. It takes the form of an online platform complemented by a mobile application for screening studies on the go. The platform is aimed at academic researchers, biopharma professionals, and health economics and outcomes research teams looking to automate literature screening, duplicate resolution, and data extraction.

• Systematic Auto-Resolver for eliminating duplicates up to 200,000 references
• ResearchPilot featuring zero-shot relevance ratings, AI Analyzer, AI Reviewer, and auto-extract data
• Risk Of Bias assessment tools for consistency and transparency
• PICO framework integration to structure study evaluation
• Workbench for dividing workloads, randomizing subsets, and managing review teams
• Data extraction capabilities to capture structured study data
• Mobile app support for working offline or on the go
• Programmable hot keys and keyboard shortcuts for faster screening

Pros

• Comprehensive workflow coverage supporting everything from reference import and deduplication to full-text screening and PRISMA reporting.
• Collaboration-friendly features allowing teams to invite reviewers, assign roles, manage subsets, and resolve screening conflicts.
• Flexible mobile accessibility that allows researchers to screen studies offline or on the go.
• Advanced AI assistance including zero-shot relevance ratings and AI-powered screening prioritization.

Cons

• The Free tier limits users to creating 3 active reviews and inviting 2 free reviewers.
• The Free tier includes limited mobile app access compared to paid plans.
• Specific pricing for the Advanced tier is cut off in the provided text.
• Advanced features like ResearchPilot and Risk Of Bias tools may require higher or enterprise tiers.

Rayyan fits academic researchers, individual investigators, small research teams, biopharma organizations, and health economics and outcomes research groups conducting systematic reviews and evidence synthesis. It is built to streamline literature screening, duplicate resolution, and data extraction workflows. It is a poor fit for projects that do not involve literature reviews, academic synthesis, or systematic evidence gathering.

The listing and website state a freemium model with a free tier and paid plans available quarterly or annually, with annual plans offering savings up to 40%. The Free tier is $0 forever and includes 3 active reviews, 2 free reviewers, industry-leading duplicate detection, AI relevance predictions, 15+ workbench facets, standard support, and limited mobile app access. The Essential tier costs $8.33 per month billed quarterly and includes all free features plus PRISMA flow diagrams, 5 free reviewers, auto-resolve duplicates, unlimited mobile app access, multi-select and bulk actions, programmable keyboard shortcuts, and a dark theme. Additional paid plans include Advanced and Enterprise options, though exact pricing for Advanced is not fully detailed in the provided text.

Unlike generic literature search tools or manual spreadsheet tracking, Rayyan provides an integrated suite specifically built around the systematic review lifecycle with automated deduplication and AI-assisted screening. It combines automated duplicate resolution for up to 200,000 references with zero-shot AI relevance ratings and customizable workbench facets. Furthermore, it incorporates dedicated collaboration features like randomized subset assignment and shared workspaces that set it apart from basic reference managers.
