Google's study tool: upload your own sources — PDFs, docs, links, lectures — and chat with them, with citations to the exact passages. Its audio overviews turn documents into podcast-style explainers.
What it is best for
Studying your own materials; exam and meeting prep.
Pricing
Free, with a Plus tier for higher limits.
Getting started
Visit the official site, sign up (most tools here take under two minutes), and test it on one real task from your actual work — a genuine document, photo or project — rather than a toy example. Real tasks reveal limits that demos hide, and most of these tools are free to try.
