SBA question generator built for medical exams
Recall Engine is an SBA question generator that turns your lecture PDFs into single best answer questions, complete with answers and explanations traced back to the exact source page.
No credit card required
Writing SBAs by hand is slow, and generic question banks rarely match your lecture. You need questions in the format your exam uses, built from the material you were actually taught.
How it works
Upload your lecture
Drop in a lecture PDF up to 50 MB. Text-based or scanned.
Choose your pages
Select the pages you want SBAs from, or run the whole lecture.
Generate and verify
Get clinical stems with answers and explanations, each linked to a source page.
Why students use it
- Clinical stems with plausible distractors built from your lecture
- Every answer traces back to a source page so you can verify it
- Credits are only charged after a successful generation
- Free to start: 30 credits on signup, no card required
Frequently asked questions
What is an SBA question generator?
An SBA question generator turns study material into single best answer questions, the format used in most medical exams. Recall Engine builds them from your own lecture PDFs and links each answer to its source page.
Can I generate SBAs from a PDF?
Yes. Upload a lecture PDF, select the pages, and Recall Engine generates SBA questions with answers and explanations. Both text-based and scanned PDFs are supported.
Are the generated SBAs accurate?
Every SBA includes a source page reference so you can check it against your lecture before relying on it. The output is grounded in your material, but you remain the final authority on accuracy.
Is it free?
You get 30 credits free on signup with no card required. Credits are only deducted after a generation succeeds.
Can I use the SBAs for USMLE, PLAB, or my university finals?
The questions come out in the single best answer format that most finals and licensing exams use, so they are good for rehearsing that style. The key difference is that these SBAs are built from your own lectures, not a fixed syllabus, so they fit your course rather than a specific exam blueprint. Treat them as targeted practice on the material you were taught, and lean on dedicated banks for board-specific coverage.
How many SBAs can I generate?
There is no fixed per-question limit. Each generation uses credits based on how much you produce, you start with 30 free on signup, and credits are only charged after a run succeeds. You can do a short set from a few pages or run a whole lecture, then top up if you want more.
Does it work on scanned or handwritten lectures?
Scanned PDFs work, since Recall Engine reads the visual pages rather than relying on a text layer. Clear handwriting can be picked up too, but messy or low-contrast scans are less reliable, so check the source page link on each SBA before you trust it. Typed slides and clean PDFs give the most consistent results.
Is this better than just asking ChatGPT to write SBAs?
A general chatbot writes SBAs from its own training, which can drift from your syllabus and invent details with no way to check them. Recall Engine builds each SBA from the lecture you upload and links every answer to the exact source page, so you can verify it against what you were actually taught. You stay the final check on accuracy either way, since this is a study aid.
