Gemini Notebook

Gemini Notebook, renamed from NotebookLM in July 2026, lets you upload documents, Google Docs, YouTube videos, and web pages, then ask questions answered strictly from those sources rather than from the open web. It generates study guides, briefing docs, FAQs, and Audio Overviews — podcast-style summaries read by AI voices. The rename came with notebooks syncing across the Gemini app, and the ability to write and run code against data in a notebook inside a sandboxed environment. It suits researchers, students, and writers who need to get on top of a large pile of sources. Free with a Google account.
