Kagi allows you to do things like inject CSS to filter out pre-translated Reddit results (although it is on their radar to make this a default setting).

Here's the CSS snippet hiding translations:

(technically you could inject it as a userscript but that's a bit more involved on mobile)

  /*
  Hide pre-translated webpages.
  "sri-group" is main result, "__srgi"  are sub results.
  You can append `:not(:has(a[href*="tl=en"]))` to allow English translations.
  */
  :is(div.__srgi, div.sri group._ext_r):has(a[href*="tl="]) {
    display: none !important;
  }

Although the main draw is being able to uprank, downrank and block sites in your results. They also do things like deprioritizing and labeling AI in image search, and concatenating listicles ("10 best Android note taking apps") under a single header.
