A book, or a question paper — both become questions that test you

AI reads any PDF you upload and quizzes you back. Already have an exam paper? It is restored, question by question, into a bank you can practise.

PDF / EPUB / DOCX / TXT / Markdown — scans are OCR-ed automatically

Two paths, one outcome

Whether you are holding a book you never finished or a paper you never sat.

Reading

Textbooks, technical books, lecture notes, papers — it understands the material first, then tests whether you do.

Exam paper

Question papers, workbooks, mock exams — it recognises a paper as a paper, not as an article.

Writing questions is not blanking out words in the original text.

Questions follow Bloom's levels — recall, apply, analyse, evaluate — not just "what was this chapter about".

Whatever you miss enters a spaced-repetition queue and returns until it sticks.

Each question stays anchored to the paragraph it came from, so you can always jump back and check.

Photographed and scanned PDFs are OCR-ed automatically; charts and formula images stay with their questions.

However many books you upload, that is how big your bank gets — the limit is your shelf, not our catalogue.
