Your PDF purchase

You buy one generation of the selected number of multiple-choice questions from your study material. The total shown before payment is a one-time price. Practice, redistributing the questions into tests and mixing saved tests do not require another purchase.

What can be processed

Only PDFs with selectable text are supported: up to 20 MB, 200 pages and 300,000 extracted text characters. At least 20,000 text characters are needed for the smallest package. Images, diagrams, scanned pages and handwriting are not interpreted. Check the extracted preview before paying. Use your own notes, public-domain content or material you have permission to process. Do not upload confidential personal information, leaked exams or real exam dumps.

Where your material goes

The free analysis runs in your browser. When you proceed to checkout, extracted text is sent to our server to verify the quote; it is not stored there. We retain purchase settings, payment references and a fingerprint of the text. The original PDF is never stored on our server. The extracted text and purchase access are stored in this browser so you can resume after payment.

After payment, when you start generation, the relevant text excerpts are sent to Anthropic. Its commercial terms and privacy information explain its processing. Stripe handles payment information. Your existing local tests and results are not uploaded.

Delivery and review

Return to this browser after payment and start generation. Keep the page open; completed batches can be resumed. Topic grouping may produce shorter tests. Questions include explanations and PDF page references, but automated checks cannot guarantee factual accuracy. Review them against your material before practising. Questions follow the language of your material.

When generation finishes, your browser is asked to download an OpenTests questions backup. Check your downloads and use the download button if your browser blocks it. Keep the file: you can restore it from My tests even after clearing browser data. The backup contains your generated questions, not the original PDF or purchase access.

Download the result within 7 days. A daily cleanup removes generated question content after that period; payment records are kept separately. Clearing browser storage removes local purchase access. Downloaded question backups can be restored in another browser. You can remove the stored source text using “Remove local purchase” after completion.

If generation cannot finish

If a generation fails or cannot deliver the selected count with source-supported questions, we initiate a full refund. Successfully generated questions are yours to keep. You can also cancel and request a full refund between generation batches. Unfinished paid purchases inactive for more than 24 hours are queued for a refund during daily cleanup. Bank processing can take several days. A pending refund remains visible in the purchase status.

For a purchase that needs help, use the merchant contact details on your Stripe receipt and quote its order reference. Do not share your study material or private purchase access publicly.
