Quizlet is a San Francisco-based global learning platform offering flashcards, practice tests, and AI-powered study tools used by students, teachers, and lifelong learners. Core features include user-created and expert-verified study sets, Learn mode (adaptive practice), Test mode, Match game, Spaced Repetition, and an AI tutor (Q-Chat / Magic Notes) that generates flashcards, summaries, practice questions, and explanations from uploaded notes, PDFs, slides, and textbooks. Quizlet Plus is the company's consumer subscription, and Quizlet for Schools / Teachers provides licensed offerings for classrooms. The platform integrates with Google Classroom (share-as-assignment) and Canvas (embeddable widgets) but does not currently expose a public developer API, OpenAPI specification, or SDK — the legacy Developer API 2.0 (`quizlet.com/api/2.0`) was effectively wound down to partners-only and is not openly registrable. Quizlet's GitHub organization (`github.com/quizlet`) hosts internal tooling, GitHub Actions, and forks of OSS dependencies (HHVM/Hack, PHPUnit, Mockery, Stylus, etc.) rather than a developer-facing API platform.
