What problem does it solve? Language learners often practice without structure, repeating what they already know and neglecting weak areas. This Skill builds a personalized session plan from the learner's streak, due reviews, weak error patterns, and recent performance, then runs interleaved exercises with adaptive difficulty. ## Core Features & Use Cases - Adaptive session planning: Analyzes six learner databases (profile, mistakes, mastery, progress, vocabulary, reviews) to pick today's focus areas and difficulty level. - Interleaved mixed practice: Combines writing, speaking, vocabulary, and reading exercises targeting 2-3 weak patterns, adjusting difficulty based on rolling accuracy. - Progress tracking: Scores every answer, logs errors and new vocabulary, and updates all databases at session end with streaks and breakthroughs. - Use Case: A Dutch learner at A1 level types /fluent-learn, gets a greeting showing a 6-day streak and 6 due reviews, chooses the adaptive mix, and completes a 20-minute session drilling word-order mistakes with immediate feedback. ## Quick Start Type /fluent-learn to start a personalized practice session based on your current level and weak areas.
