That is how AI works.
Most AI... Gosh, I'm not sure what to call it here, models, agents, tools? Whatever, most AI things nowadays don't just rely on their dataset, they can also make queries out to the web. So, yes, making sure AI tools can easily get answers from your website is a real thing companies need to be aware of. Because the reality we live in now is that most people's search engines have an AI Summary at the top, and that's all most people are going to look at. Most people were already stopping at the first search result prior to this.
It has a term I think? AIO maybe? I don't remember. Basically like SEO but for AI.
