Litmaps vs Rayyan (2026)

Litmaps

by Litmaps

Rayyan

by Rayyan

Pros

• ✓Every plan, including Free, includes literature alerts, so a map keeps surfacing newly published papers after the first search is done.
• ✓Pro has an education rate of $10 per month billed annually, a quarter of the commercial rate, and country-based discounts cover more than 100 countries.
• ✓Two-way Zotero sync on Pro, plus BibTeX, RIS and PubMed import and BibTeX, RIS and CSV export, fit Litmaps into an existing reference workflow.

Limitations

• –Litmaps finds and maps papers but does not write summaries or extract data from them, so reading and synthesis happen in another tool.
• –Free alerts run monthly on the default algorithm only. Weekly alerts, algorithm choice, filters and Zotero sync all require a Pro plan.
• –Team and Enterprise prices are not published, and Litmaps documents no public API or MCP server for connecting it to other tools.

Pros

• ✓A usable free plan with duplicate detection and AI relevance predictions, and paid seats from $4.99/mo billed annually.
• ✓Covers the whole screening workflow in one place: import, duplicates, blind screening, full-text review, data extraction, risk of bias and PRISMA diagrams.
• ✓Rayyan says it is used by more than 1 million researchers at more than 30,000 institutions, and it offers iOS and Android apps that screen offline.

Limitations

• –It screens references a team has already gathered; it does not search literature databases for them.
• –ResearchPilot's AI Reviewer starts on the Business/Academic plan at $2,500 a year for 5 licenses, and the API and SSO need the custom-priced Enterprise plan.
• –A thin independent review record: no G2 reviews and 3.6 stars from 240 reviews on Google Play, and SOC 2 Type II and ISO 27001 are shown as engagements rather than completed certifications.
