About
Harrison.ai is a Sydney, Australia-based healthcare artificial intelligence company founded in 2018 by brothers Aengus and David Hallinan that builds clinical-grade AI models for diagnostic medicine, initially targeting radiology and pathology. The company''s flagship product — Annalise.ai — is a comprehensive AI platform for radiology interpretation that analyzes chest X-rays, CT scans, and other medical imaging studies to detect and flag a broad range of findings simultaneously. Unlike earlier radiology AI tools designed for single conditions, Annalise.ai is a multi-finding model trained to detect up to 124 findings in a single chest X-ray and 295 findings in chest CTs — providing a comprehensive AI second reader experience rather than a narrow single-disease detector.
