The Big Idea

The secret is a free tool from Google called NotebookLM. The mind behind it designed it so you can upload your personal collection of documents: notes, PDFs, articles, even video transcripts, and create a private knowledge base. You can then chat with this custom AI, which will only pull information from the sources you provided. It’s like having a personal research assistant that has read everything you’ve ever saved.

This is such an awesome way to interact with your own work and research. The expert shared a few key points on how it functions:

  • Upload Your Sources: You can add up to 50 different documents to a single project. Think of it as creating a custom library for your AI to study. This could be your meeting notes for work, research papers for a thesis, or even your favorite recipes.

  • Chat with Your Data: Once your sources are uploaded, you can interact with them just like you would with ChatGPT. Ask it to summarize a long report, find a specific quote from a video, or even create an interactive podcast where you can literally talk to your documents.

  • It’s Grounded in Your Content: This savvy professional clarifies an important detail. While NotebookLM is powered by a large language model (Gemini), it’s designed to ground its answers only in the documents you’ve provided. So, you get the reasoning power of a massive AI with the focused knowledge of your personal library.
