AI-personalized case preparation you can be confident in. Delphi is an AI case prep assistant for orthopedic residents, fellows and surgeons. Ask about a case, an approach or the evidence, and Delphi answers from trusted orthopedic textbooks, journals and surgical video, not the open web. Every claim is cited to the exact page it came from. Using PrecisionOS VR? Delphi also points you to the VR case that matches your question, so you can practice it in your headset. EVERY CLAIM IS CITED Each blue number links a statement to its source. Tap one to see the title, edition, pages and why it was cited, then read the full excerpt. Rate any reference with a thumbs up or down. SEE THE CASE, STEP BY STEP Figures from the source textbook open right in the app, with the caption and chapter, so you can see the exposure, the osteotomy or the implant step instead of just reading about it. PRACTICE IT IN VR For PrecisionOS VR users: when a VR case is relevant to your chat, Delphi tells you what it's best for learning and lets you queue it to your headset in one tap. Search the PrecisionOS VR case library from the app, then practice the case in a lifelike virtual environment and build the 3D spatial skills that reading alone can't give you. SEE HOW YOUR VR CASE WENT After each VR case, open your Insights report: session time, a win, a gap and what to practice next. Open the full report for the detail, so every rep counts. PITFALLS AND LIMITS UP FRONT Answers flag the key pitfalls and call out their limits clearly, so you know what to confirm with your attending or your planning software on the day. ANSWERS THAT FIT YOUR TIME Tell Delphi how long you want to spend reading, from 30 seconds to 5 minutes, and how you like your answers: bullet points, short paragraphs, diagrams or video. Change the length of any answer with a slider. Length changes, rigor doesn't: every answer checks the same sources. PREP WITH YOUR OWN CASE MATERIALS Upload your notes, attending preferences and case documents, then ask what you should be thinking about for that case.
