Brief

polydao frames NotebookLM plus Obsidian as a high-leverage knowledge-compression stack, especially when paired with Gemini and the YouTube-to-NotebookLM extension. The core claim is that AI can ingest large volumes of overlapping sources, summarize them quickly, and compare new material against an existing knowledge base so users focus only on novel information.

THIS IS HOW YOU COMPRESS 100 HOURS INTO 10 MINUTES > just tried NotebookLM + Obsidian combo and honestly… this is insane > i didn’t expect NotebookLM to be this powerful the craziest part? > the "YouTube to NotebookLM" extension you can literally pull entire channels, dump all videos into NotebookLM and get a structured mega-summary in minutes > but two features completely blew my mind: Audio Overviews: > turns any PDF, report or notes into a podcast-style dialogue between two hosts > perfect for listening while walking or driving Book Filter: > upload your Obsidian knowledge base + a new book ask: "Is there anything new for me here?" if the answer is "no" skip it and save dozens of hours > this feels like compression for knowledge if you’re serious about learning fast, here’s the stack: 📁 NotebookLM ↳ https://notebooklm.google.com 📁 YouTube to NotebookLM Chrome Extension ↳ https://chromewebstore.google.com/detail/youtube-to-notebooklm/kobncfkmjelbefaoohoblamnbackjggk… 📁 Google Gemini ↳ https://gemini.google.com/app this combo + Obsidian vault = unfair advantage
