Rayyan has become the default tool for systematic and literature reviews in academic and clinical research, and it earns that position by solving the genuinely tedious parts of evidence synthesis: deduplication, collaborative screening, and bias assessment, with a layer of AI assistance (ResearchPilot) that speeds up prioritization without fully replacing human judgment. The free tier is generous enough for individual researchers, while institutional and enterprise plans add API access, advanced extraction, and team management features that larger research groups need. It's not flawless: the AI suggestions still need verification against domain expertise, and the breadth of features can overwhelm new users before they've internalized systematic review methodology, but as infrastructure for evidence-based research it's hard to beat.
