Tiago Forte. Tiago is the *Building a Second Brain* author and treats NotebookLM as exactly what the article describes — a personal RAG over your own notes, PDFs and clippings. He shows the citation-grounded chat, the limits of the tool, and how it fits next to a Readwise/Obsidian workflow, which is the natural endpoint for most readers of the article.
The durable lesson is source grounding, not the exact NotebookLM interface. Re-check current sharing, retention and source limits before using this with workplace or client documents.

Have a small set of notes, PDFs or transcripts you are allowed to upload to a third-party tool.
