I've been using Kagi for two months and I'm loving it - the ability to control your results is amazing. Some things I do:

• remove or downrate things like pinterest and w3schools from my results
• rewrite www.reddit.com/* to old.reddit.com/*
• rewrite to send some sources through archive.today or similar to break paywalls
• rewrite to set the language of some sites that GeoIP my location but ignore my language headers

Also, having keyboard controls - like Google used to have - is so welcome, and their AI summarisation tools are actually useful too.
