AI Overviews (AIO)
The short summary written by artificial intelligence appearing at the top of Google's search results page, which answers your question directly based on multiple websites.
In plain terms
Once, Google was like a librarian who placed ten books before you in response to your question, and you had to find the answer within them. AI Overviews are like the librarian flipping through the books themselves, summarizing the essence in a few sentences, and citing the source.
Above the search results, a framed text box appears: this is the AI-generated summary, accompanied by links to the source pages. You do not need to enable it separately, and it does not appear in every search, but rather for more complex questions requiring explanation.
It differs from a chatbot in that it is not a separate application but integrated into the familiar search engine. It is convenient for you because you get answers faster, but it is a problem for website owners, as many no longer click through to the source.
How it works
- You enter your query into Google, and the system decides whether to provide a summary for that search.
- The search engine runs several related queries in the background when needed and gathers the websites most relevant to the topic.
- Google's language model, Gemini, formulates answers of a few sentences or bullet points from the text of found pages.
- References to the sources the system relied on are added to the answer, allowing you to verify the claims.
- Below the summary, the traditional list of results remains. Ads may appear above, below, and in some countries even within the summary itself.
An everyday example
You search for how to remove a red wine stain from a carpet. Above the results, a step-by-step guide appears alongside links to three or four source pages, and you likely click on none of them because you have already received the answer.
Who is affected
A common misconception
Limits and risks
- It can err: the summary may contain inaccurate, outdated, or outright fabricated statements, so always open the source for important matters.
- Use it only as a starting point for health, legal, and financial questions, not as a basis for decisions.
- You cannot see why it chose those specific sources, nor is it certain that it relied on the most reliable websites.
- You may receive a different summary for the same question at a different time or with different wording.
Similar, but not the same
- AI Mode – AI Mode is Google's separate, chat-like search interface where you can ask follow-up questions. AI Overviews is a summary box on the traditional results page, from which Google increasingly redirects you to AI Mode if you want to ask more.
- featured snippet – The highlighted excerpt is a verbatim quote from a single webpage, while AI Overviews is text rewritten from multiple sources.
- chatbot (e.g., ChatGPT, Gemini) – With a chatbot, you converse in a separate application for longer periods, whereas AI Overviews appear without a request during normal searches.

A brief history
Google introduced the experimental predecessor of this feature in May 2023 under the name Search Generative Experience (SGE). In May 2024, it was renamed AI Overviews and launched widely in the United States, then gradually in other countries.
Where things stand
At the end of 2026, Google Search is a routine part of life in much of the world, in many languages. Meanwhile, publishers and website owners continue to dispute how much traffic it takes from them. This has led to court cases, and the European Commission has also opened an antitrust investigation.
