FluentU uses authentic video content—such as music videos, commercials, and news clips—as its foundation for language lessons. The platform features interactive subtitles that allow users to click on any word for a definition, example sentences, and pronunciation. New vocabulary can be saved as flashcards, which are then reinforced through personalized quizzes. While it offers a method for learning vocabulary in context and improving listening skills, it does not provide explicit grammar instruction or speaking practice.
Taalhammer is designed for serious learners who want to move beyond basic vocabulary drills. Its core methodology involves learning and internalizing full sentences to build intuitive fluency. The app uses an AI-powered spaced repetition system to train you on sentence structures. A key feature is the ability to add your own content—words, articles, or phrases—and the app will build personalized lessons around it. It's a powerful tool for building a strong core of usable language, though less focused on explicit grammar rules.
