Medical knowledge you can interact with

Evidence-checked health guides.

Read the guide, then check the evidence behind it — every source shown, every cited DOI retraction-checked, and every review status stated honestly.

Guides matching your question appear as you type — every claim checked against its source. Asking directly happens in the ModernDoc app, coming soon.

Start with a question, end with evidence you can check.

How every page is made

Guides are AI-assisted research summaries. Before publication, every article must pass nine automated gates — in the order they run:

  1. Style & regulatory review
  2. Uniqueness
  3. Structure & schema
  4. Content integrity
  5. Citation resolution — every cited DOI is checked against CrossRef retraction data
  6. Claim-to-source entailment
  7. Safety judge
  8. Multi-persona review panel
  9. Adversarial refutation

Passing automated checks is not the same as clinician review — and we say so. A named reviewer appears on a guide only after reviewing the exact version shown; until then its review status reads “Medical review pending,” and an edit voids any prior approval. Each released guide carries a release certificate binding its exact content; if a page stops matching its certificate, it comes down automatically.

Know when the evidence changes

Each research monitor offers email updates: ModernDoc emails you when a validated finding on that page is added or corrected — nothing else, no fixed schedule, double opt-in. Sign up on the monitor you care about:
