Missed, weak, and fading words return through personalized review so you can build active recall instead of only recognizing words. Key features: - Sentence-based vocabulary practice - Personalized review from mistakes and weak words - AI-generated sentence assignments algorithm - Writing feedback for sentence accuracy - Progress and vocabulary insight - Practice across multiple learning languages Sentence Monster is built for learners who freeze when writing, even though they already know many words.
