NotebookLM, explained simply
NotebookLM is an AI notebook from Google. You add your own sources, like PDFs, notes or web pages. Then you chat with an AI that answers from them.
It matters because the answers come from your material, not the open internet. It also shows where each answer came from.
For example, you could upload a class reading list and ask for a study guide.
It can still make mistakes, so check the cited parts.
