YouTube is the world's largest educational library, and all the knowledge is completely locked away

You cant search across all channels. You cant really ask questions. You cant feed it into an AI agent. Billions of hours of lectures, tutorials, interviews, and expertise, trapped inside video files. I want to fix that. The idea: pull transcripts from any public YouTube channel and turn them into a queryable AI knowledge base. Point it at any creator and just ask it things. Is this worth building? What channels would you unlock first?
