Show HN: I built a complete AI learning system for YouTube

I've been self-learning from YouTube for years—everything from coding to design to business skills. But I kept hitting the same wall: YouTube learning has no structure. Your knowledge gets scattered across random playlists, you're passively consuming content without real retention, and when you're confused, there's nobody to ask.

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.
