DDX Engine for Physicians
Intended use
For licensed physicians to brainstorm differential considerations; not for diagnosis, treatment, or triage.
Vaid MD is clinical decision support software for licensed Canadian physicians. All outputs are worksheets and drafts for physician review — you confirm every diagnosis, treatment plan, and disposition after independent verification in certified clinical sources.
Structured clinical thinking for differential review — considerations to explore, red flags to review, and documentation instruments in one copilot workflow.
A worksheet for licensed physicians to brainstorm differential considerations before you set your working diagnosis.
Curated differentials for high-impact specialties
- Dermatology: pattern-based rashes and lesions surfaced quickly.
- Cardiology: chest pain, dyspnoea, and syncope workflows tuned to CCS guidance.
- Family Medicine: broad, primary care oriented DDx lists that mirror real clinic days.
Built to expand, not replace, your own clinical reasoning. Specialty templates narrow the search space faster.

What It Does
Every presentation benefits from structured differential review. The DDx Engine supports your brainstorming of conditions to consider before you set your working diagnosis. Structured by Canadian guidelines, ordered by review priority, with transparent rationale and sources to verify.
How It Works

Your judgment. Always. The output supports your thinking, never replaces it.
Canadian Clinical Context
Canadian guidelines by default. CCS, CMA, and provincial practice standards applied to every output - not US protocols adapted for Canadian use.
