Free PDF Quiz Generator

Turn a PDF into an interactive quiz for free. Focus on relevant study content, save PDFs in your account, and review your test scores over time.

Upload your PDF

PDF format and file size

Upload a PDF up to 500 MB. Text-based books, lecture readings, and notes work best. Questions are generated from extracted text, so image-only pages and diagrams may not provide enough material for useful questions.

Turn your reading into a test of understanding

Upload a book, lecture reading, or other PDF and answer multiple-choice and open questions about its content. Start as a guest without creating an account. Calten is free, with unlimited usage and no subscription.

Focus on study content, skip reference sections

Calten identifies sections such as bibliographies, reference lists, indexes, and about-the-author pages and excludes them from question generation. It focuses on the relevant reading content rather than asking you to memorise source lists or author details.

Save uploaded PDFs in your account

Create a free account to keep the PDFs you upload in your Library. Return to your saved documents when you want another practice session, instead of uploading the same reading again.

Review past tests and follow your scores

Your account keeps your test history and shows your performance over time in Progress. Review previous results and score trends to decide what to revisit.

Create a test from multiple PDFs

Revising several readings together? Save your PDFs in your account, select the documents in your Library, and start one test using that selection. Follow the multiple-PDF quiz walkthrough for the full workflow.

Check generated answers against your reading

AI-generated questions and answers can contain mistakes. If an answer seems unclear or surprising, check it against your PDF. Very short documents may produce a shorter test when there is limited material to ask about.
