I did something similar, when the Kagi Translate changes were announced earlier in the year. I tried a local hosted AI assistant (via openrouter) along with DDG/Brave.

80% of the time the search results were perfectly fine, but that small amount of time would royally annoy me and my breaking point was this: https://i.redd.it/r4q6y3vl5vdh1.png

So I went back to Kagi and appreciate it a little more (they've also rolled back on Translate to some degree).
