HOW ADAPTIVE GRAMMAR WORKS
> Your mistakes become lessons
ENCOUNTER
> You are in an AI conversation and say something ungrammatical. The AI tutor flags the error, corrects it, and saves the grammatical pattern to your grammar collection.
LESSON GENERATION
> The platform generates a targeted lesson explaining the grammatical rule you broke. Not a generic lesson — a lesson about the exact pattern you need. With example sentences drawn from your own lexicon and mistakes.
STRUCTURAL EXPLORATION
> Each grammar lesson includes a vertical exploration: how the pattern works at the discourse level, phrase level, word level, and morph level. Understand why the structure works, not just what to say. This is the difference between memorizing rules and internalizing structure.
LANGUAGE-SPECIFIC MODULES
> Grammar modules are built by a computational linguist for each language. Japanese pitch accent. Arabic case morphology. Spanish subjunctive. Korean honorifics. German case declensions. Every module reflects the actual structure of the language, not a one-size-fits-all framework.
STOP MEMORIZING. START UNDERSTANDING.
