Earthworm is an AI-powered language learning platform centered on sentence construction, translation exercises, and grammar tutoring. It integrates a spaced repetition system to schedule reviews based on individual performance and a multimedia practice tool that converts audio, video, and text into interactive sentence-level exercises.
The platform features a real-time competitive quiz system where users can challenge each other in live matches based on speed and accuracy. It also includes an AI tutor that provides contextual grammar and usage explanations for specific sentences, and a set of analytics dashboards that use heatmaps and growth curves to track study streaks and performance metrics.
Learning is supported through incremental sentence construction and multi-modal sessions that allow users to switch between translation, dictation, listening, and speaking modes. The system also facilitates social learning through collaborative study groups and shared leaderboards.
