Science, or slop?
A paper can read well sentence by sentence while its science does not connect. Unlike token-level AI detectors, the Science Slop Index reads the scientific reasoning: whether sections build on one another, claims and citations are argued, and the method and evidence can be inspected.

}How it works
Six measures, three planes, one number
Each measure counts the share of a paper's units that show one pattern. The index averages the measures within each plane, then averages the planes, and reports the result out of 100. Higher means more of the patterns that set AI-generated papers apart from matched human papers.
Reads the paper, not the prose
AI text detectors score sentences: how predictable each token is, how a model would have phrased it. A paper written or revised by a language model can pass that test and still fail as science. Each paragraph looks fine on its own while the connections between paragraphs do not hold: a figure that no section ever refers to, a claim that arrives before anything leads up to it, a related-work paragraph that lists citations without relating them, a method diagram crowded with hyperparameters, a results table with no concrete example anywhere in the paper.
The Science Slop Index counts these breakdowns. It reads the whole paper, groups six patterns into three planes, and asks three questions. Below, each plane is illustrated with real findings from the papers analyzed on this site; use the arrows to browse them, and click a finding to open it on the paper.
What happens to a paper
Every report receives a key that reopens it later. Uploaded files are deleted after analysis; only the report and rendered figures stay.
1Read
LaTeX source is read directly; arXiv links fetch the source and the PDF. PDFs are rebuilt into sections, captions, references, and citations.
2Measure
Four measures are exact counting rules. Argument graph and Figure exposition ask a language model to label sentences and read the method figure.
3Highlight
Every flagged unit is placed back on the PDF, colored by plane, with a graph per measure. Export as highlighted PDF, JSON, or CSV.
The six measures
After Table 1 of the paper. Each score is a share of units: the numerator over the denominator. Pair accuracy is how often that measure alone ranks the human-written paper above its AI-generated counterpart on SciSlopBench.
One number
The index averages the measures within each plane, then averages the three planes. A measure that does not apply to a paper is skipped, not counted as zero.
The four bands are descriptive cut-points on the share of flagged units, not a probability of AI authorship.
Reported pair accuracy
Table 2 of the paper: on SciSlopBench, 390 AI-generated papers each matched with a human-written paper on the same problem. 0.5 is chance.
