For most very simple use cases -- like, I don't know, if you want to know how to sort a list in Kotlin -- just using the Kagi in-search assistant is more than enough, you can search with: "sort list kotlin, code example?" (with the question mark) and you'll get brief explanations with code examples based on search results (or whatever. I don't know, it works).

The model they're using for these must not be a very good one, but for most things it's enough, and very fast.
