I've been using Kagi for a couple of years now. For awhile, my work Chrome profile was still set to use Google for search by default because I don't login to personal accounts on it. I didn't use search that often for programming work - I used ChatGPT or Claude much more often - so it was always incredibly shocking to me how terrible Google search was every time I used it.
The AI results were bad beyond all human understanding - the sort of product that I thought only a walking corpse like Microsoft could release so broadly. But, that is essentially what Google Search is now. Clearly no one in a position of responsibility knows or cares about product design or performance and it only continues to exist through sheer inertia.
Switching to Kagi is how it felt when I first used broadband internet in college , or when I switched from Alta Vista to Google: the internet works like it should.
