Flexi

Flexi is an AI-powered flashcard app designed for language learners to build and retain vocabulary efficiently. The app leverages artificial intelligence to automatically generate flashcards with translations, example sentences, and definitions at no cost, while image generation is available for Premium subscribers. Flexi employs a spaced repetition system that schedules reviews at increasing intervals, optimizing long-term retention. Users can jot down new words and phrases as quick notes and later convert them into study cards. A daily streak tracker, text-to-speech pronunciation, home screen widgets, and Siri Shortcuts keep learning frictionless and motivating. Premium features include AI-generated word suggestions tailored to the learner's level and interests, as well as the ability to import existing flashcard decks from Anki and Quizlet. The app is built for anyone wanting to expand their vocabulary in a structured, tech-enhanced way, whether they are casual learners or dedicated polyglots.
