PDFQuiz
A focused document-to-quiz tool that does the boring parts well: OCR on scans, explanations with every answer, and an Anki export so the questions outlive the site. Entry pricing is genuinely cheap if you accept annual billing. The awkward part is the metering — quotas are counted in characters converted, which is hard to plan against — and the operator publishes no company details at all.
Pros
- Accepts eleven-plus file types including scans and photos, with OCR
- Exports to Anki and PDF rather than locking questions inside the site
- Shareable graded quizzes with a timer and invitation tracking
- Interface localised into more than 25 languages
- Every generated answer comes with an explanation
Cons
- Quotas are counted in characters converted per month, which is opaque
- API access, Zapier and white-labelling sit only on the $38/month Elite tier
- The 20 MB per-file cap rules out full textbooks
- No company name, address or legal entity published anywhere
