It may sound strange, but just as a word processor is a tool designed to make it easy to create, edit, and format text documents, and a tool like Photoshop is designed to make it easy to manipulate pixels in a digital image, NotebookLM is a tool designed to make it easy to swap different kinds of information in and out of a language model’s context window. That doesn’t sound like much of an advance, but long context turns out to be one of those innovations that opens a lot of new doors. Source grounding was powerful enough when the context window could hold a few thousand words. But a world where models now can focus on millions of words creates entirely new possibilities.
