Students read short decodable stories aloud and complete spelling tasks matched to exactly where they are in their school's phonics program, and LitLab listens to and analyzes every word a child reads to pinpoint which letter-sound patterns they have mastered and which still need work. This gives every student far more individualized practice than a typical classroom can provide on its own, and because it works even when a teacher has limited time to differentiate, it is especially valuable in under-resourced schools. Since mastery is measured continuously as a byproduct of practice, that same evidence flows back to teachers as specific, lesson-level insight grounded in their existing curriculum, collapsing the gap between when a student starts to struggle and when a teacher can respond from weeks to days.
