Lune vs CoResearcher

CoResearcher takes a reference list and matches each entry against academic indexes: verified, mismatched, or not found. Lune goes one step further and asks whether the paper actually supports the sentence citing it.

Where the difference comes from

Two ways a citation goes wrong

The loud failure is the fabricated reference: a plausible title, plausible authors, no such paper. CoResearcher catches that, and its own wording is the right instinct, that each reference is looked up rather than guessed by a language model.

The quiet failure is worse for a reviewer. The paper exists, the DOI resolves, and it does not say what your sentence claims. Metadata cannot catch that, because the answer is in the text.

Why full text is the requirement

Checking a claim means finding the sentence that supports it, or establishing that no such sentence exists. Both need the paper, not the record for the paper.

That is why Lune indexes accepted papers in full and returns the quote with its location. gather_evidence goes further and names what evidence is still missing rather than writing around the gap.

What we read

Questions

Is Lune a CoResearcher alternative?
It covers the same worry and goes further, but CoResearcher checks any reference list against broad indexes, including papers outside Lune's corpus.
Can Lune check a whole bibliography?
It checks claims rather than reference lists. Point verify_claims at the sentences and it answers each with a quote or with nothing found.
Can I use both?
Reasonably, yes. Run a reference-existence pass over the bibliography, then check the claims that matter against the text.
