Better questions, not just more questions
Most AI quiz tools produce shallow recall questions that only test whether you memorised a sentence. Calten generates questions that check understanding — the kind that actually prepare you for exams, not just make you feel like you studied.
Focuses on content worth studying
Calten automatically identifies and skips low-value sections like bibliography, references, about the author, appendix, and index. Questions are generated from the meaningful study content — the parts of your PDF that actually matter.
MCQs and open-ended questions from the same PDF
The AI quiz generator creates both multiple-choice questions and descriptive questions so you can test surface recall as well as deeper understanding from a single upload. For a full walkthrough, read how to generate questions from a PDF.
Active recall beats passive rereading
Instead of rereading notes and feeling like you understand them, create a quiz from your PDF to test yourself on the material. Retrieving information from memory is consistently more effective for long-term retention than re-reading.
