A browser extension and mobile app that uses AI to analyze content in real-time, identifies learning opportunities at your exact level, and overlays micro-exercises (fill-in-the-blank, sentence reconstruction, audio shadowing) that appear between paragraphs or during natural video pauses. It extracts unknown words, grammar patterns, and accent variations from your content, then schedules them for active recall practice without interrupting your primary activity.

Large language models can now accurately assess text/video difficulty, generate contextually appropriate exercises, and provide instant feedback. The explosion of foreign language content on streaming platforms and e-readers creates a massive, untapped dataset for personalized learning at scale.
