The reasoning engine is the product. Ranked differentials, cited clinical question answering across a 38 million article index, and drafted assessment and plan are all model outputs, and the Developer API sells that intelligence directly as a component to other platforms.

The strongest structural answer to the hardest problem in clinical AI. Every response carries inline citations to source literature and guidelines, so a clinician can verify any individual recommendation against the evidence rather than trusting the output. The company insists on the product being decision support requiring physician judgment on every output, and it declines to position it otherwise. Verifiable reasoning plus a stated ceiling on autonomy is the right posture for differential generation.

Unusually specific about what the system reasons over: an index of more than 38 million peer reviewed articles, consensus guidelines, and FDA information covering over 154,000 drug compounds, with inline citations exposing the sources of any given answer. For a decision support product, disclosing the evidence corpus and making every output traceable to it is the substantive form of transparency, more useful than naming a base model.

Evaluated in the Harvard and Stanford ARISE NOHARM benchmark, a physician validated clinical safety evaluation, where the platform ranked among the top medical AI systems. Independent safety benchmarking by academic institutions is a materially stronger evidence position than vendor accuracy claims, and it is the appropriate evidence standard for a product that proposes differentials. Independent testing also documents the limits, noting reasoning is weaker on complex multi system cases than on common presentations.

Freemium with a genuinely usable free tier for individuals covering limited scribing and decision support, and a Pro plan reported around $90 per month, with enterprise and Developer API pricing quoted through sales. A clinician can evaluate and adopt without procurement. Held back from A because the Pro figure comes from third party review rather than a published rate card, and API pricing is entirely undisclosed.
