| Description | Consensus is an AI-powered academic search engine that uses language models to find and synthesize answers from peer-reviewed research. Ask questions in plain English and get evidence-based answers with citations from scientific papers. | Gemini Notebook (formerly 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. On 2026-07-16 Google rebranded NotebookLM to Gemini Notebook (same product; notebooks preserved). Sold via Google AI Plus / Pro / Ultra bundles. Enterprise product: Gemini Notebook Enterprise. |
