Overview
What you provide
- Supply one or more seed articles and select the citation or semantic discovery method available to your plan.
What you get
- Litmaps returns a literature map with suggested papers and configurable monitoring.
Choosing this tool
Litmaps is useful when a seed paper is known but a keyword list misses neighboring work. Its default citation algorithm and paid Similar Text semantic search solve different discovery problems. ResearchRabbit is an alternative for paper-network exploration; Semantic Scholar is a direct search and alert starting point when a visual map is unnecessary.
A decision worked through
A review with 140 relevant papers exceeds the listed Free map capacity of 100 by 40. Reducing the list may serve a pilot, but splitting a systematic review solely to fit a free cap can fragment the evidence trail. Verify the selected Pro eligibility before using its advertised annual price in a project budget.

| LitmapsRead profileOfficial source ↗ | Pro from USD 10/mo annually | 2 maps; 100 articles each | Seed papers become a map. | Advanced algorithms need plan access. |
| ResearchRabbitRead profileOfficial source ↗ | Free literature-discovery entry | Core research maps | Seed papers become related literature. | A graph does not assess study validity. |
| Semantic ScholarRead profileOfficial source ↗ | Free scholarly search | Search and research alerts | A query becomes papers and metadata. | Read original studies for conclusions. |
Setup & workflow
- Seed a map with a paper you have already read.
- Compare the default citation recommendations with semantic results if your plan allows them.
- Export or record the screened papers and document why each was retained.
Requirements & installation
- Create a research account and identify at least one relevant seed article.
Limits & review
- Similar Text analyzes titles and abstracts rather than validating study findings. Free and advanced discovery allowances differ; the plan page contains multiple variants, so use the rendered selected offer.
Your part
- Read abstracts and full papers to decide relevance; a recommendation is not an evidence-quality assessment.
