Kagi has been the closest thing to the google from 2003 that I’ve encountered in a long time. I’ve not tried their assistant that’s only available on the ultimate plan as it’s too expensive for me. FWIW, I have the duo plan, soon to move to the family plan.
The quick answer usually works pretty well and you have access to fastgpt if you want more of the LLM effect.
I got one from my utility company. They installed it at the meter. It was about $400. Once it’s tripped, it will have to be replaced, but if something happens significant enough to trip that, I probably (hopefully) saved a lot of other large appliances and HVAC.
