## Verdict

One of the most useful free research tools available. It complements rather than replaces web-search assistants, since it only knows what you give it.

## What it is

Each notebook holds up to dozens of sources; answers cite passages and refuse to stray beyond the material, which reduces fabrication. Audio Overviews turn sources into a podcast-style discussion, and additional outputs include briefing docs, FAQs, timelines, and mind maps. Sharing lets teams build notebooks together.

**What makes it different:** Strict grounding in your own sources with inline citations, plus distinctive audio overviews for learning on the go.

**Best for:** students, researchers, and teams who want reliable answers and summaries from a defined set of documents

**Not ideal for:** open-ended web research or tasks requiring information beyond your uploaded sources

## Key features

- **Source-grounded Q&A** — Answers cite passages from your uploads only.
- **Audio and video overviews** — Generate discussions and explainers from sources.
- **Study outputs** — Briefing docs, FAQs, timelines, and mind maps.
- **Collaboration** — Share notebooks with teammates or classes.

## Use cases

- **Exam preparation** — Turn lecture notes into study guides and audio.
- **Research synthesis** — Question a set of papers or reports.
- **Onboarding packs** — Give new hires a notebook of key documents.
