AI tools
Check an AI tool on your own patients
Enter the counts from a sample of your own patients. The page returns sensitivity, specificity, positive and negative predictive value with 95% confidence intervals, beside the vendor's claim and our review's figures, and says plainly when the sample is too small to tell.
The calculator is for Plus and Pro members
Enter counts from your own sample and see each measure with its 95% interval, the vendor's claim beside it and our review's figures. It runs in your browser; nothing is sent.

Intervals are Wilson score intervals at 95%. We call an interval too wide to tell when it spans more than 20 percentage points.
The arithmetic runs in this page. Nothing you enter is sent or saved. Enter counts only, never patient details.
