Rayyan web tool

Rayyan web tool provides a centralized environment for researchers to screen, tag, and manage large literature sets used in systematic reviews or evidence syntheses. It is designed for researchers, librarians, and project managers who coordinate multi-author screening and need reproducible decision trails. The tool supports import of bibliographic references and organizes them into projects with configurable labeling schemas and screening stages.
Conceptually, users create a project, import references in RIS, BibTeX, or CSV, and define screening stages (title/abstract, full text). Each reference gets one or more labels (Included, Excluded, Pending). Screening rounds can be performed blind to other reviewers, and decisions are tracked with an audit trail. Conflicts are surfaced for adjudication and resolved to produce a final included set.
Value and differentiation include speed, collaboration, and transparency. Real-time updates reduce duplicate screening and conflicting decisions, while structured labeling supports downstream data extraction and PRISMA mapping. Export options include CSV, RIS, or EndNote-compatible formats, enabling seamless integration with workflow tools and reference managers.
Core features and use cases cover import of multiple reference formats, label templates, bulk tagging, search-based filtering, conflict management, and auditable decision logs. Typical users run living reviews, rapid evidence assessments, or multi-project scoping. The tool is particularly valuable in settings requiring reproducible screening processes, collaboration across institutions, and a clear evidence trail for reporting and governance.
