Litmaps
Pros
- + Citation-map visualization surfaces related papers outside your keyword search — three genuinely new relevant papers in my first ten minutes of mapping
- + Literature monitoring: alerts on new work in your mapped space, daily and configurable on Pro versus a monthly summary on Free
- + Real reference-manager ecosystem — two-way Zotero sync on Pro, plus BibTeX/RIS/PubMed import and export
- + Free tier is usable for real trialing (one map, 100 articles) and the paid tier is $10/month, $120/year at time of writing per litmaps.com/pricing
- + Education and parity pricing (academic email discounts, LMIC country parity) make it accessible outside well-funded labs
Cons
- - No reading layer: no summarization, no Q&A over full texts, no claim-level citation checks — it maps, you read
- - Maps sprawl into an unclickable hairball past roughly 150-200 articles in my experience
- - Free plan caps at 1 map and 100 articles (litmaps.com/pricing shows both '2 Litmaps' and '1 Litmap' in different views on the same page — inconsistent)
- - New preprints appear late or mis-placed in maps because the graph depends on citation data
- - Team features require contacting sales — no self-serve shared maps for small labs
Rayyan
Pros
- + Zero-shot AI relevance predictions genuinely reorder the screening queue — relevance ranking appeared within seconds of import in my testing with no training examples
- + Blinded duplicate screening with conflict resolution and dedup that caught conference-abstract/journal-article near-duplicates my DOI pass missed
- + Workable free tier: 3 active reviews, 2 reviewers, duplicate detection and AI predictions included — enough for a real first review
- + PRISMA flow diagram generation (Essential+) saves hours of manual diagramming per review
- + Cheap paid seats — $4.99/seat/month billed annually per third-party listings, $8.33/month billed quarterly per rayyan.ai at time of writing
Cons
- - AI predictions prioritize the queue but must not replace human duplicate screening decisions — no trustworthy auto-inclusion
- - Not a literature-search tool: does not run database searches or find studies for you
- - Advanced form customization and branching logic are thinner than DistillerSR/EPPI-Reviewer-class enterprise tools
- - Healthcare/medical-first user base and templates; other fields work but the community flavor is clinical
- - Pricing signals conflict across third-party listings versus the vendor page — verify before budgeting
