[Three Core Innovations]

• AI-Tailored Articles No grinding worksheets. AI generates fresh articles every day based on your child's CEFR level and interests (science / sports / history / stories). Difficulty auto-adjusts after each reading session.

• 6-Color Polysemy Magic (Exclusive) "Run" has six meanings in one article? AI auto-classifies every occurrence and tags each sense with a unique color: yellow for "to run", purple for "to flow", orange for "to operate", and so on. See multi-sense words at a glance, no more flipping dictionaries.

• 4D Pronunciation Scoring Powered by Microsoft Azure Speech (same engine used by Duolingo): four-dimensional scoring on accuracy, fluency, completeness, prosody. Every mispronunciation gets targeted feedback in the user's chosen UI language.
