An AI-powered language learning platform that generates flashcard decks from various sources (topics, URLs, or raw text) using OpenAI. Users can browse public decks, create custom decks with optional text-to-speech audio, and track learning progress through a spaced repetition system (SM-2 algorithm) with accuracy, mastery, and streak metrics. Built with Laravel 13 + Vue 3 + Inertia.js. Uses OpenAI GPT-4o-mini for generation and TTS-1 for text-to-speech audio on cards.
