AI-overview was the straw that broke the camel's back for me recently. But I also suffered from dark mode issues for a long time. On almost every visit, it shows the outer background dark but the smaller search results background as white, and the search result text is still in light mode, ergo, it is not readable. After refreshing, it works, but this user experience is untenable for a trillion-dollar company. I changed to Startpage.com, though.
When you do want an AI overview you can have Kagi do that by adding a ? at the end of your query. It flows nicely for me as the difference between searching for something, or just asking the internet a question. Kagi cites sources and allows you to move the conversation to a new LLM session.
I love that I have taken humanity’s oldest technology and complicated it to the point where I have the same problems as the buildings running our very newest technology. Makes a good brisket though.
