Rayyan
Officially listedAn AI-driven systematic review platform that speeds up literature screening for academic researchers.
Rayyan
Rayyan is an AI-driven systematic review management platform designed for academic researchers, developed by Qatar Computing Research Institute and spun out as an independent US startup in 2020. Using active learning algorithms, it cuts literature screening time by up to 90%, serves more than 1 million researchers worldwide, and has been cited over 21,000 times, making it one of the most recognized screening tools in the field.
Core Capabilities
- Smart AI screening: the active learning algorithm starts learning your decision patterns after 50-100 records are screened, with a 5-star rating system predicting literature relevance
- ResearchPilot™ AI suite: AI Reviewer for automated bulk screening, AI Analyzer for on-demand deep analysis, and Auto Extraction to pull data from PDFs and fill forms automatically
- Collaboration and blinding: multi-user real-time collaboration, blind screening mode, and conflict resolution, with team task division and role-based permission management
- Mobile exclusive advantage: native iOS/Android apps support offline screening, so research advances anytime in spare moments
- Best-in-class deduplication: the automatic dedup feature is rated highest in accuracy and sensitivity, with 15+ import formats and integrations with mainstream reference managers
- PRISMA compliance: automatically generates PRISMA flow diagrams, supports the PICO framework and Risk of Bias assessment, meeting Cochrane systematic review standards
Use Cases Systematic reviews in medicine and health sciences, large-dataset literature screening (5,000-100,000 records), multidisciplinary collaboration teams, PhD dissertation literature reviews, and budget-constrained academic research. Especially suited to exploratory research that needs mobile work and fast iteration.
Unique Advantages Its AI screening technology leads Covidence's basic machine learning, with real-world tests showing 50-70% less reviewer workload. It is the only tool in its class with a mature mobile app that supports offline work, and the free version offers 3 active reviews with no time limit (competitor Covidence charges $3,000+ per review). The learning curve is the shortest around — new users are up and running within 1-2 hours.
Editor's Review Research Gold's 2026 comparative review noted that “for large reviews with 5,000+ records, Rayyan's AI can save weeks of screening time,” and in a BMC academic evaluation 100% of respondents said they would keep using it. The launch of ResearchPilot™ marks a strategic shift from “AI-assisted tool” to “AI-native platform.” Note that it focuses mainly on the screening stage — data extraction and quality assessment are comparatively weak — so it pairs well with tools like RevMan.

FAQ
Is Rayyan free?
It offers a generous free version with 3 active reviews, 2 invited reviewers, basic AI relevance prediction, and limited mobile app access, with no time limit. Paid plans start at $4.99/month (billed annually).
What are Rayyan's main features?
Core features include AI-driven smart literature screening (5-star relevance prediction), multi-user collaboration with blind screening, industry-best automatic deduplication, offline mobile screening, PRISMA flow diagram generation, and the ResearchPilot™ AI suite (institutional edition).
How much time can Rayyan save?
Officially, the AI can cut screening time by up to 90%, and researchers on average report saving 80%. Real-world tests show that after screening half the records, 86-99% of the relevant literature has already been identified.
How does Rayyan differ from Covidence?
Rayyan specializes in AI screening efficiency (its active learning outperforms Covidence's basic machine learning) and mobile experience, with a more generous free version; Covidence is an end-to-end platform covering the full workflow of screening, data extraction, and quality assessment, but charges more ($3,000+ per review).
Which research fields is Rayyan suited for?
Originally designed for systematic reviews in medicine and health sciences (developed in partnership with Cochrane), it has expanded to engineering, social sciences, education, and other disciplines. It supports the PICO framework and PRISMA standards, and is especially suited to systematic reviews handling large datasets.
What is special about Rayyan's mobile app?
It is the only systematic review tool in its class with a mature mobile app (iOS/Android), supporting offline screening (work without a network after downloading, with automatic sync once you reconnect), so you can advance research in fragments of time like commutes.
What is Rayyan's ResearchPilot™?
ResearchPilot™ is an AI suite exclusive to the institutional edition, including AI Reviewer (automated bulk screening), AI Analyzer (on-demand deep analysis), Auto Extraction (automatic data extraction from PDFs), and a multilingual Help Center, representing the strategic direction of an AI-native platform.
Which reference managers does Rayyan integrate with?
It supports Zotero, Mendeley, EndNote, and other mainstream tools. Mendeley in particular is directly integrated, letting you search and import from its library of 100 million+ references. Import formats include RIS, BibTeX, CSV, XML, PDF, and 15+ more.
