What our research says

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

Quizlet

Quizlet is still the default for exam-cramming flashcards because the library is enormous and the free tier covers set creation and the main study modes; the AI additions are convenient rather than essential. Pay for Plus if you hate ads or want the generated practice tests, but if you care about long-term retention, Anki's free spaced repetition remains the stronger tool.

Pros

Largest public library of study sets, searchable by course and textbook
Set creation, Learn, Test and Match modes are free, with ads
Plus is free for verified teachers, and school licences exist
Web, iOS and Android apps with offline study on mobile

Cons

Free tier shows ads and holds back the AI practice tests and explanations
Site and apps have moved features in and out of the paywall repeatedly, so older advice is unreliable
Annual plan auto-renews after the 7-day trial and the monthly plan has no trial
No public API for building on the set library
