    Demos

    Four working demos of clinical AI.

    01

    Wellness Planner

    An AI wellness planner: a personal daily plan for sleep, meals, movement and what you already take.

    It supports wellness and never diagnoses; when something needs a doctor, it says so.

    Open demo
    02

    Triage case studies

    An AI routes six fictional patients, and I grade it against my own answer key.

    Every answer was written by a physician before the AI saw the case.

    Open demo
    03

    Cardiovascular risk

    The validated Framingham 10-year score, explained in plain words and without alarm.

    The math is the published model; the AI only explains what the person can change.

    Open demo
    04

    Brevai

    A long clinical note turned into diagnoses, medications and plan, the way a clinician scans it.

    Sample notes only, never real patients.

    Fairer language models

    Ask a chatbot "Do you sell my data?" in a different English dialect and the answer gets worse. Our multi-agent framework closed most of that gap.

    Gap between dialects with GPT-4o-mini, lower is better: 80% smaller.
