FAQ

How is this different from calling an LLM directly?

Answers are retrieved from a scholarly corpus and every claim carries a checkable source with a page locator. Claims the model could not ground are labeled. See citation.

What is the difference between a paper and a document?

A paper is in our corpus; a document is yours. See paper and document.

When should I use search vs chat?

Search finds papers and answers across the corpus. Chat answers questions about a fixed set of sources you name. See search.

How much does a call cost?

Metered in credits, reported per response in X-Credits-Cost. See pricing-and-credits.

How long does a deep review take?

Minutes. Stream it or use a webhook. See streaming-deep-review.

Can I store the results?

Do you train on my uploads?
