EvidenceGrid AI vs Rayyan

EvidenceGrid AI is a web platform for research teams conducting systematic literature reviews. It automates paper screening, data extraction, and conflict resolution. Searches run across PubMed, OpenAlex, arXiv, Europe PMC, and CORE at the same time. AI pre-screens papers against review criteria and flags borderline cases for human review, while kappa scores are calculated during screening. Reviewers can upload PDFs or fetch open-access versions, then annotate them in the built-in reader. Teams define custom extraction fields; AI finds values in full text for approval or editing. Decisions are timestamped and attributed, and exports include approval audit trails. Evidence grids export to Excel, CSV, or structured JSON with PRISMA flow counts. Co-reviewers can receive role-based access and shared annotations. The workflow guide says it aligns with PRISMA 2020 and Cochrane standards. The Free plan costs nothing, includes 10 papers and 3 AI extractions, and requires no credit card.

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.
