Turn a lecture PDF into exam practice questions
Recall Engine turns any lecture PDF into practice questions, from SBAs and MCQs to flashcards, with answers and explanations linked to the exact page each one came from.
No credit card required
You have the lectures but not the questions. Generic question banks rarely match what you were taught, and writing your own from a PDF by hand is the slowest part of revising.

Frequently asked questions
Can I turn a PDF into questions?
Yes. Upload a lecture PDF, select the pages, and Recall Engine generates practice questions with answers and explanations. Both text-based and scanned PDFs work.
What question types can I generate from a PDF?
You can generate SBAs, MCQs, flashcards, or high-yield notes from the same PDF.
Are the questions accurate?
Every question links to the source page it was built from, so you can verify it against your lecture. The output is grounded in your material, but you remain the final authority on accuracy.
Is it free?
You start with 30 free credits and no card. Credits are only charged after a successful generation.
Does it work on scanned or handwritten lecture PDFs?
Scanned PDFs work, since Recall Engine reads the visual pages, not just the embedded text. Clear scans of printed lectures give the best results. Handwritten notes are harder, so the cleaner and more legible the page, the more reliable the questions, and you can always check each one against its source page.
Can I use the questions to prepare for my university finals or USMLE-style exams?
Yes, and because the questions come from your own uploaded lectures rather than a generic bank, they match the syllabus your finals are actually set from. You choose SBAs or MCQs to mirror your exam format. Treat it as targeted practice on your material, not a replacement for the official curriculum or a full question bank like a real prep resource.
How many questions can I make from one PDF?
There is no fixed per-PDF cap. You pick the pages and the format, and a longer page range or a bigger set uses more credits, which are only charged after the generation succeeds. With the 30 free credits on signup you can run a full lecture and see the output quality before deciding to do more.
