Clinical exposure is uneven. Rotations are short. Preceptors vary. And true readiness is difficult to measure.
Built by physicians and medical educators, DDx helps medical schools deliver consistent, validated case-based training across each competency domain for every learner — without adding faculty burden.
DDx’s medical education library includes cases across key dimensions, empowering educators to decide where to place emphasis based on their learners, curriculum goals, and clinical context.
DDx gives programs a scalable, engaging, accreditation-aligned pathway to strengthen clinical reasoning, communication and technical skills.




“The platform allowed the students to engage deeply within the diagnosis process and practice reasoning in a structured and interactive format. They were really, really excited that day when we were using the tool for the first time.”Dr. Nicole Rassi, MD, FACPAssociate Professor, University of Puerto Rico School of Medicine
Sketchy awarded grants to 12 U.S. medical schools to strengthen evidence-based clinical reasoning training across the curriculum through the adoption of DDx. Schools are integrating DDx into pre-clerkship courses, clerkships, residency programs, and CME, using platform data to enhance assessment, remediation, and coaching.
