The Slop Index Tool
An open leaderboard scoring how much like generic AI prose a model writes, combining blind pairwise crowd votes with mechanical style measures against a pre-2022 human reference corpus. Methodology and generations are public; treat the rankings as a prototype, since the project's own published counts do not reconcile.
GPTZero Tool
The widely used AI-writing detector (about 19M users) that estimates how likely a passage was machine-generated; being acquired by Superhuman to build a persistent authenticity layer.
