The thing I like here is that it runs locally. I use Vim keyword completion[1] a lot for next-word completion. It does a broadly similar sort of "look at surrounding code to offer good suggestions" thing (no LLM stuff, of course). It's wrong often, but it's useful enough that it saves me time overall, I feel.

So, this sounds to me like an expanded version of that, more or less.

I think I'd prefer an AI future with lots of little focused models running locally like this rather than the "über models in the cloud" approach. Or at least having such options is nice.
