Scite
scite.ai
An academic research tool that classifies how papers cite each other — distinguishing supporting, contrasting, and mentioning citations — so you can see whether a paper's claims have been confirmed or challenged.
Why it is useful
Citation counts alone don't tell you whether subsequent research agreed with a paper. Scite's Smart Citations show exactly how a paper has been received — how many papers supported its findings, how many challenged them, and the exact excerpt showing how it was cited. Essential for quickly assessing whether research findings are holding up under replication, or if a highly-cited paper is actually controversial.
