Turn a clinical PDF into USMLE-style questions in minutes

Every medical educator knows the grind. Writing a single good clinical vignette with a realistic stem, plausible distractors, and a clear explanation can eat an entire afternoon. And every student knows the other side of it—revising from a dense guideline can feel passive and slow. 

Roediger and Karpicke (2006) found that, after initial study, retrieval testing produced better long-term retention than additional restudying, demonstrating that tests can enhance learning as well as assess it. Building that practice by hand is the bottleneck on both sides of the classroom. Either way, the same thing is true: the knowledge is already sitting in a PDF. It just isn't in a form you can practice with yet.

CLARA helps remove that bottleneck. Short for Clinical Learning And Review Assistant, CLARA is a joint project from Medmastery and Life in the Fast Lane. Upload a clinical PDF, such as a guideline, a review article, or a textbook chapter, and CLARA drafts USMLE-style questions grounded in that exact source. It's powered by AI, turning hours of item-writing into a quick review-and-edit pass. CLARA writes the first draft, and you can review and refine it in minutes.

Here's how it works, in three easy steps.

First, upload. Drag and drop a clinical PDF, and CLARA extracts the text and prepares it for question generation.

After you’ve completed the upload, CLARA will offer two options for types of quizzes you can generate: clinical cases, which are USMLE-style patient vignettes, or a study quiz, consisting of multiple-choice concept questions.

Second, let CLARA generate the questions. It drafts full clinical vignettes with plausible distractors, explanations, and high-yield pearls all tied back to the source you uploaded. The result is designed to resemble the style of a USMLE question, with a specific patient scenario and a focused clinical decision. 

The correct answer and a teaching pearl linked back to the source material are also provided.

Third, share a magic link. Publish your quiz and copy a shareable link. Students can take the quiz on any device with no login required. Educators can view responses and the score distribution.

CLARA was created by medical educators from Medmastery and Life in the Fast Lane and is designed to make AI-generated questions easier to review and verify. Each question cites the section it was drawn from, and each teaching pearl points back to your uploaded source, so you can quickly check the content against the original material.

Really, it works for both sides of the classroom. Faculty and course directors who need realistic items fast can draft 20 questions before lunch instead of spending a whole day writing a handful from scratch. Students and residents get output in the style of USMLE practice questions tailored to exactly what they're studying, and don't even need an account to take a quiz. Because every quiz is built from a document you choose, the practice can be tailored to the syllabus, the rotation, or the exam you’re preparing for.

CLARA is simple to use and grounded in your selected source. You can try CLARA for free, with no credit card required. You can write your first quiz in under five minutes—about the time it takes to drink a coffee. Create your first quiz today!
