Trust Is a Link, Not a Promise
Osler answers clinical questions with numbered inline citations drawn from eleven source families — guidelines, PubMed, Cochrane, trials and more — 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
No sources, no safety
A generic chatbot delivers medical claims with total confidence and zero references. You are left guessing which parts are real.
- 2
Verification costs more than the answer
Checking an unsourced claim means searching PubMed and the guidelines yourself — the exact work the AI was supposed to save.
- 3
Yesterday’s medicine, presented as today’s
Without a cited society and year, you cannot see whether an answer reflects current guidance or a version that has since been replaced.
Inline citations
Every Claim Carries Its Sources
Osler answers with numbered citation chips inline — [1], [2], [3] — placed exactly where each claim is made. Hover a chip for a source card; click it to open the full sources sheet, scrolled to that source.
