What is Litmaps?
Visual literature mapping tool that discovers connected research through interactive citation networksLitmaps is a visual research discovery platform that helps academics and researchers explore scientific literature through interactive citation maps and automated discovery algorithms. The platform transforms the traditionally linear process of literature review into a visual, networked experience where researchers can see how papers connect to each other through citations and discover overlooked work that bridges different research areas. Users start by entering a seed paper or set of papers, and Litmaps generates a dynamic map showing citation relationships as nodes and edges, with papers positioned chronologically and sized by influence. The Discover feature automatically identifies papers that are highly connected to the user's existing map but not yet included, surfacing relevant work that might be missed through keyword searches alone. Litmaps monitors newly published papers and alerts users when new work connects to their existing maps, ensuring ongoing awareness of developments in their research area.

- +Smart discovery finds relevant papers you would likely miss otherwise
- +Automated monitoring alerts you when new relevant papers are published
- •Graduate students starting literature reviews
- •Systematic review teams building comprehensive bibliographies
- •Interdisciplinary researchers bridging multiple fields
What is Semantic Scholar?
AI-powered academic search engine that surfaces the most relevant and influential research papersSemantic Scholar is a free AI-powered academic search engine developed by the Allen Institute for AI that helps researchers find and understand scientific literature more efficiently than traditional databases. The platform indexes over 200 million academic papers across all fields of science and uses machine learning algorithms to extract key information, identify influential works, and surface the most relevant results for any query. Unlike keyword-based search engines, Semantic Scholar understands the semantic meaning behind research queries and can identify papers that are conceptually relevant even when they use different terminology. The platform's TLDR feature generates concise, plain-language summaries of papers, allowing researchers to quickly assess relevance without reading full abstracts. Citation analysis tools show not just how many times a paper has been cited but categorize citations by type, distinguishing between background references, method uses, and result comparisons.
- +Completely free access to a massive database of 200M+ academic papers
- +AI-generated TLDR summaries save significant time during literature review
- +Citation type classification provides deeper understanding of paper influence
- •Academic researchers conducting literature reviews
- •Graduate students exploring research landscapes
- •Research librarians curating scholarly resources
