What to watch out for
Ai2 PaperFinder is a strong discovery aid, but its coverage is academic and may not include every source you need, so treat it as one tool among several. Synthesized answers are convenient but should be checked against the original papers before you cite or rely on them, since a summary can flatten important detail. The site returned a redirect status during review, so confirm it loads, and remember that access to some full texts may still depend on the publisher or a subscription.
