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
Connected Papers
Pros
- + Co-citation and bibliographic coupling surfaced conceptually adjacent papers that plain citation tracing missed in my field-mapping runs
- + Five full graphs per month free with every feature included and no account required to start
- + Academic plan at $6/month (at time of writing) with unlimited graphs is among the cheapest paid upgrades in academic software
- + Prior Works and Derivative Works views gave me the field's foundations and its current frontier in two clicks
- + Scholarship program exists for researchers who cannot pay — email the team for a discounted or free plan
Cons
- - Five free graphs disappears in one review afternoon; the free tier is a demo with monthly resets for active researchers
- - Graphs seeded from very recent papers are sparse — co-citation signal needs time and citations to accumulate
- - Shows relatedness only: no summaries, no quality judgment, and no reproducible search for PRISMA-style reviews
- - Coverage inherits Semantic Scholar's gaps — humanities, law, non-English and grey literature are thin or absent
- - No alerts for new matching papers, no API, no app, and BibTeX download as the only export
