Lune vs DATA SWEEP

DATA SWEEP searches 250 million academic sources semantically and rates what comes back with a trust score. Lune covers far less ground and answers with the sentence instead of a rating.

Where the difference comes from

A score is a judgment you cannot audit

DATA SWEEP's trust score is an honest attempt at the right problem, which is that a retrieval system should say something about how much weight a source carries.

The catch is that a score is the system's opinion, arrived at by a process you cannot see. If it is wrong, nothing about the output tells you. A quote fails differently: you read it, and either it supports the sentence or it does not.

Coverage where it counts

Thirty-odd publishers is real breadth, and for biomedical or engineering work it reaches literature Lune has no plans to index. If that is your field, this is a genuine advantage and we will not argue it away.

Inside computer science the relationship flips. The venues that matter are conferences, Lune reads them in full, and the tools answer with the exact line rather than a ranked result.

Both aim at it differently. They score sources; Lune returns the quote and reports when it found no support.
Does DATA SWEEP have an API?
None is listed on their site. It is used through the web interface.
