| Description | NotebookLM is Google's AI research assistant that works exclusively with documents you upload, rather than the open web. It generates summaries, answers questions grounded in your sources, and creates Audio Overviews — podcast-style conversations between two AI hosts discussing your material. Designed for students, researchers, and professionals who need to make sense of large document collections. | Scite is an AI-powered citation analysis tool that shows how papers have been cited - whether supporting, contrasting, or mentioning. Helps researchers evaluate the reliability of claims and find the most relevant evidence in scientific literature. |
