Lune vs NeuraLumi

NeuraLumi's argument is that keyword search returns the wrong papers, so it ranks 200 million of them with NLP instead. Lune agrees about keywords and goes at the problem from the other end, by reading fewer papers properly.

  • Your problem is that search returns the wrong papers, across every field.

Choose Lune if

  • You want the retrieval inside your agent, not in a search box.

Where the difference comes from

Two fixes for the same complaint

Everyone in this category is reacting to the same thing: keyword search over titles and abstracts returns papers that share words with your query and nothing else.

NeuraLumi fixes it by ranking better across everything. Lune fixes it by indexing less and reading it in full, so a query can match a sentence in the methods section rather than a phrase in the abstract.

What happens after the ranking

A better ranked list is still a list. The next step, reading the papers and working out what they support, stays with you.

Lune's tools take that next step. extract_from_papers lines up several papers as a typed table, and verify_claims answers a sentence with the quote behind it. Neither is possible from a ranking alone.
