Google Notebook

AI-powered virtual research assistant: it analyzes and summarizes user-uploaded documents (PDFs, websites, video transcripts) using Google Gemini.

Google NotebookLM (LM for Language Model) is your AI-powered research partner, a tool from Google Labs that launched in 2023 as Project Tailwind. The platform leverages the powerful Gemini model to analyze and interact with your specific source material: upload up to 50 documents, including PDFs, Google Docs, and website links, per notebook. It generates summaries, creates study guides, and answers complex questions, grounding every response in your sources for verifiable, cited insights. NotebookLM is available on the web and via dedicated mobile apps, providing a focused environment for deep document analysis and content creation.
