Rayyan vs Systematicly

Rayyan is a platform for teams carrying out systematic evidence reviews, with workflows intended to be transparent, auditable, and reproducible. Its process spans reference import, collaboration, deduplication, title and abstract screening, full-text screening, data extraction, risk-of-bias assessment, and reporting. ResearchPilot AI Reviewer screens articles against criteria set by the user and gives decisions with reasoning notes. The Analyzer suggests inclusion or exclusion with justification, while the researcher retains final decision-making. ResearchPilot can also extract answers to custom questions from PDFs and metadata, highlight relevant passages, and let users inspect the answers. References are imported from exported files rather than a direct database connection. The API offers programmatic access to reviews, references, decisions, and metadata, plus workflow automation and external integrations. Rayyan is available on Android, iOS, web, and through an API. The Free plan allows three active reviews and two free reviewers; paid options start at $8.33 a month per seat, billed annually. Free mobile access is limited; Essential and higher provide unlimited mobile access.

Systematicly is a web-based research platform for systematic reviews, primary research, ethics applications and research proposals. It can analyze a topic using PICO, PECO or SPIDER frameworks and produce Boolean searches for databases including PubMed, Scopus, Web of Science, ERIC and PsycINFO. Reviewers can screen titles and abstracts and upload PDFs for structured field extraction. Analysis options include 1,033 statistical functions, plain-English analysis, meta-analysis, plots, sensitivity analysis and GRADE assessment. The platform lists eight review types, plus publishing tools such as AI-assisted manuscripts and proposals, PRISMA diagrams, journal recommendations and reviewer response letters. It retrieves PDFs automatically from PMC, Unpaywall and EuropePMC, and supports ClinicalTrials.gov imports and several reference formats. The free Explorer plan is limited to three active personal drafts, one lifetime feasibility preview and three lifetime Evidence Answers. Paid one-time options include a single Evidence Answer for $19, paid once and literature review packages from $149, paid once. The security page says user data is not used to train AI models; Anthropic’s commercial API may retain inputs and outputs for up to 30 days for trust and safety monitoring.
