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.
