PathTools.ai Information

PathTools.ai builds AI that grades prostate biopsies the way pathologists do: gland by gland. Our grader maps every gland on a whole-slide image, assigns it a Gleason pattern, flags cribriform architecture and perineural invasion, and rolls the result up into core- and case-level grade groups. Pathologists see why the model made each call, not just a heat map. Built for real-world labs: • Trained on 100,000+ glands hand-drawn by pathologists across 800+ annotated slides • QWK 0.849 vs. expert grade group on public cohorts; cancer detection AUC ~0.99 across Hamamatsu, Leica and Grundium scanners • 500 biopsy cores per GPU hour • Runs as a cloud API or as a licensed container on your own hardware, so PHI never has to leave your network Who we work with: • Pathology groups and urology labs adding AI-assisted prostate review and LDT validation • Pharma and CROs needing quantitative H&E readouts for biomarker and CDx studies • Scanner and platform partners integrating prostate grading • Academic groups running research collaborations PathTools was founded by practicing pathologists Anthony Perry MD and Jared Szymanski MD together with Dennis Della Corte PhD, BYU professor and former CSO of ZONTAL (acquired by Bruker). We publish our methods openly: whitepaper and peer-reviewed benchmarks at pathtools.ai. Based in Provo, Utah.
