Google AI Overviews are AI-written summaries that appear at the top of some Google Search results, with links to the web pages behind them.
In plain words
For some searches, Google uses generative AI to write a short snapshot of the answer and lists supporting links so you can read more. They only appear when Google's systems judge they add something beyond normal results, so many searches show none. To build one, Google may run several related searches across subtopics, a method it calls query fan-out. Google warns they can make mistakes, so checking the links matters. You can continue into a longer chat in AI Mode.
A quick example
Imagine you search for why the sky turns red at sunset. An overview at the top gives a short explanation of how light scatters, with links to science pages underneath. If you want more, you type a follow-up question and carry on in AI Mode.
