Source-grounded research notebook

Google's source-grounded research notebook. Add your sources — PDFs, docs, slides, web pages, even YouTube — then ask questions, build notes, and generate Audio Overviews that summarize them like a podcast.

  • Grounded in the sources you add, with citations
  • Ingests many source types — web, slides, video
  • Audio Overviews turn sources into a podcast
  • Built for studying & research, less for structured output
