Harrison.ai: The Sydney Medical AI Company Behind Annalise and Australia’s Radiology Revolution

Harrison.ai is a Sydney-based medical AI company that has built some of the world’s most sophisticated AI systems to assist clinicians with radiology and pathology, with products now used in hospitals and clinics across Australia and internationally.

What Harrison.ai Does

Harrison.ai develops AI-powered clinical decision support tools. Its flagship product, Annalise.ai, analyses chest X-rays and CT scans, detecting up to 124 different findings: including subtle signs of pneumonia, fractures, and cancer: and flagging them for radiologist review. A second product, Harrison Clinical, extends AI-assisted analysis to pathology workflows. Both products are designed to work alongside clinicians, improving speed and accuracy of diagnosis.

How AI Powers Harrison.ai

Annalise.ai was trained on millions of anonymised medical images, making it one of the most comprehensively trained radiology AI systems in the world. The deep learning models identify patterns in imaging data that correlate with specific clinical findings, providing confidence scores and visual overlays so clinicians can see exactly what the AI detected and where: a transparent tool that supports rather than replaces clinical judgment.

Why It Matters for Australia

Harrison.ai is a flagship example of Australian AI at the frontier. Having raised over $129 million and earning regulatory approval in Australia, the EU, and other markets, it demonstrates that Australian startups can build world-class AI products in highly regulated, high-stakes domains: and compete globally.
