Frequently Asked Questions
Is QuizFlex better than Anki?▾
It depends on your needs. QuizFlex excels at AI-powered content creation — upload a PDF, paste a YouTube link, or record a lecture and get flashcards and quizzes instantly in 30 languages. Anki is a powerful, highly configurable spaced repetition tool favored by medical students and language learners who want granular control over their review schedule. If you want speed and ease of use, QuizFlex is better. If you want maximum customization and don't mind manual card creation, Anki is a strong choice.
Can I use QuizFlex as a free Anki alternative?▾
Yes! QuizFlex offers a free plan with 50K credits per month, AI-generated flashcards with FSRS-based spaced repetition, quizzes, analytics, and sharing — all in a modern web interface. Unlike Anki, which requires separate apps for each platform (and $25 for iOS), QuizFlex works on any device through the browser.
How does QuizFlex spaced repetition compare to Anki?▾
QuizFlex uses the FSRS (Free Spaced Repetition Scheduler) algorithm, which is a newer, research-backed alternative to Anki's SM-2 algorithm. FSRS adapts more accurately to individual learning patterns and has been shown to improve retention with fewer reviews. Anki also supports FSRS as an opt-in feature, but QuizFlex uses it by default with no configuration needed.
Does QuizFlex have quizzes or just flashcards?▾
Unlike Anki which only supports flashcards, QuizFlex offers multiple study formats: AI-generated multiple-choice quizzes, true/false questions, flashcards with spaced repetition, and printable worksheets. You also get live quiz hosting for classrooms and study groups — something Anki cannot do.
Can I import my Anki decks to QuizFlex?▾
Direct Anki deck import (.apkg) is not yet available. However, you can export your Anki cards as text or CSV files and paste the content into QuizFlex — our AI will generate enhanced flashcards and quizzes from your material automatically, often adding additional context and question variety.
