I built Notetube to fix this by layering organizational tools with AI to create a proper learning system:
Organizational layer: Build structured collections by topic/course/skill, visualize your learning progress with dashboards, create and track your learning goals
AI layer: Automatically generates detailed notes (3000+ words for 1 hour of content) and summaries, identifies key moments with timestamps, creates personalized quizzes for retention testing, and provides a chat interface for instant help when concepts aren't clear
...plus additional features like timestamped note-taking, but I'll keep this brief.
Quick signup via Google OAuth for a smooth onboarding experience.
