The Scenario

Quizlet’s 60M+ monthly users study vocabulary across languages and subjects. When a learner encounters “retention” in a flashcard set, Quizlet can fetch a verified definition, IPA pronunciation, 47-language translations, and an aligned quiz from Orb instead of relying on user-generated or LLM content. Same word, same definition, every study session — deterministic content that scales across millions of learners.
