The Ultimate Knowledge Base: Bring YouTube Into Your AI Second Brain

• Converts an entire YouTube channel’s transcripts into a single markdown knowledge base that drops directly into Obsidian, extending the Karpathy “LLM wiki” pattern to any channel, not just Cole’s own.
• Adopts Google’s Open Knowledge Format (OKF), the emerging LLM-wiki standard, so an agent can immediately learn how to navigate the knowledge base without bespoke instructions.
• Identifies “canonicalization” — collapsing dozens of videos covering the same idea into one clean page — as the hardest part of the pipeline.
• Ships 3 Claude Code skills and a public example repo (cole-medin-knowledge-base) so viewers can build the same pipeline for any channel with a single prompt.
• Takeaway: channel-to-knowledge-base conversion is now a repeatable, agent-ready pipeline (transcript extraction + canonicalization + OKF), lowering the cost of tracking many creators at once.
