In their own words
LitMap
LitMap is a web tool for analyzing papers and organizing a literature review. Users upload PDFs, and the service extracts claims, methods, and findings. AI extraction can also identify definitions and limitations, with editable results. Papers are clustered by semantic similarity on a visual canvas that users can rearrange. LitMap highlights disagreements with side-by-side quotations and lets users mark them resolved or unresolved. Its gap finder identifies missing populations, methods, or timeframes. Users can arrange papers and themes into an outline, then export organized notes with citations as Markdown, CSV, or JSON. LitMap does not write literature-review prose or paraphrase sources. The site says it works offline, keeps data in the browser, and requires no account. It is labeled beta. The Free plan costs nothing and allows five projects with 50 papers per project; Student costs €5 a month, and Academic costs €25 a month.
Rayyan
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.
