Lacuna Research
Claude connectorCommunitySearch 2.3 million ML and AI papers, the researchers behind them, and the research directions they form.
Lacuna is a knowledge graph of machine learning and AI research. It covers 2.3 million papers from major ML venues, arXiv and OpenReview, 215,000 authors, 6,200 venues, and 28,000 research directions: clusters of papers that share ideas, methods or findings.
With this connector, Claude can:
- search papers, authors, research directions, venues, institutions and research proposals
- read a paper's summary, figures, key concepts, related papers and other versions
- look at an author's papers, research directions and similar researchers
- explore a research direction, a venue (optionally by year) or an institution's authors
- find code repositories, datasets and models linked to papers (GitHub, Hugging Face, Zenodo)
Every result has a Lacuna URL, so Claude can cite pages you can open and check. All tools are read-only, and no account is needed.
