Flashy is a modern, intuitive flashcard application built with Next.js 15 that helps users study effectively through digital flashcards. The application features a clean, responsive interface with smooth animations and dark/light mode support, allowing users to create, organize, and study flashcards seamlessly. Users can create custom groups for different subjects, add detailed descriptions, and manage their flashcards with a preview system that shows exactly how cards will appear during study sessions. The study system includes features like randomized card presentation, keyboard shortcuts for navigation (arrow keys and spacebar for flipping), and group-specific study sessions. What sets Flashy apart is its focus on user experience, with features like instant local storage persistence (no account required), toast notifications for action feedback, and a fluid card-flipping animation system. The application was built using TypeScript for type safety, Tailwind CSS for styling, and shadcn/ui components for a consistent design language. Key features include the flashcard management system, study mode with shuffle functionality, and group organization capabilities that allow users to structure their learning materials effectively.
