Clinical AI You Can Actually Check
Ask a clinical question and Osler answers with numbered inline citations drawn from eleven source families — guidelines, PubMed, Cochrane, drug labels and trials — each one click from the primary source.
The problem
A Confident Answer Is Not Evidence
Generic chatbots answer medical questions fluently and source-free. In medicine, an answer you cannot verify is an answer you cannot use.
- 1
Confident answers, zero references
A generic chatbot states medical claims with total certainty and no sources. You are left guessing which parts of the answer are real.
- 2
Verifying costs more than asking
Checking an unsourced claim means searching PubMed and the guidelines yourself — the exact work the AI was supposed to save you.
- 3
The safety checks live in other tabs
Interaction checkers, guideline PDFs and literature databases are each a separate destination, so the check that matters is the one that gets skipped.

Everything Osler can do
Cited answers, automatic interaction checks, guideline-grounded recommendations and a knowledge profile that grows with every question — one clinical AI you can actually check.
Automatic drug safety
Name Two Drugs. Osler Checks.
Mention two or more medications anywhere in a question and Osler detects them, resolves each via RxNorm — the US National Library of Medicine’s drug terminology — and grades the known interactions. There is no separate checker to open and no form to fill.
- Checking happens automatically inside the conversation
- Brand and generic names resolved via RxNorm
- Severity normalized to high, moderate or low
- High severity promoted to the top with a red warning, never trimmed
Interactions found · 3
Simvastatin + Amlodipine
Raised simvastatin exposure — myopathy risk
Lisinopril + Metformin

Warfarin + Ibuprofen

Normalized to high · moderate · low — the serious one leads
Guideline-grounded
The Recommendation, With Its Society and Year
Guidelines are Osler’s premier source type: recommendations arrive cited with the society and the year, gold-coded on the exact claim they support. Where societies differ, the positions surface as separate cited sources instead of one averaged answer.
- Society and year on every guideline citation
- Differing societies cited side by side
- Full text one click away in the Prognia guideline library
- Guideline deep-dive pages also live in Ward
