How do you transform a mountain of scattered data into an organized "Second Brain"? In this masterclass from InfosecTrain, we dive into the world of source-grounded AI. Learn how to combine the power of NotebookLM, Google's Gemini-powered research assistant, with Oboe, an advanced tool for transcribing and structuring unstructured audio. Whether you are a researcher, content creator, or knowledge worker, this episode provides a high-level blueprint for building a private, secure, and hyper-efficient knowledge system.

📘 What You’ll Learn:

Source-Grounded AI: Discover why grounding your AI in personal documents (PDFs, transcripts, notes) eliminates hallucinations and ensures accuracy.
Under the Hood: A look at the Gemini family of models and how they are optimized for long-context research and speed in 2026.
Mastering NotebookLM: How to upload up to 50 sources per notebook to create an "instant expert" on any project or topic.
The Oboe Advantage: Using specialized AI to capture raw meeting audio and unstructured data, turning "noise" into high-signal information.
The Synthesis Workflow: A pro-level demonstration of moving from raw audio (Oboe) to a searchable, summarized "Project Bible" (NotebookLM).
Privacy & Security: Understanding why your data remains yours and is never used for training external models.

🎧 The ultimate guide for anyone looking to research faster, write better, and make smarter decisions with AI.
