Aignostics released PathoSearch in early access, a visual search engine for pathology: from a screenshot of a region of interest on an H and E slide it retrieves morphologically similar, diagnosed reference cases so a pathologist can build a differential in minutes. Search runs on embeddings from Atlas 2, Aignostics' pathology foundation model co developed with Mayo Clinic, against a curated multi centre reference set of more than 310,000 whole slide images from over 35,000 cases spanning more than 300 diagnostic entities across 27 organs, covering thoracic, digestive, soft tissue and bone, female genital, and urinary and male genital cancers at launch. The first integration is live inside Techcyte's Fusion AP slide viewer, where a selected region is passed to PathoSearch without export or upload. PathoSearch is free during early access, by waitlist, and is labelled research use only, not for diagnostic procedures.
Our readRare and complex cases are where a pathologist reaches for a textbook or a paid consult, and image similarity search against a diagnosed reference set is a plausible replacement for the first of those. The research use only label is the operative constraint: this cannot be part of a signed out diagnosis today, and a lab evaluating it should treat the Fusion AP integration as the way to try it inside the workflow rather than as a clinical deployment.
