I've tried Kite once, and wasn't really impressed. For example, back when I tried it, it wouldn't offer any kind of autocompletion within a string. Even vim's built-in autocomplete tries to complete words for you there, based on other words you've used before.

Kite did sometimes offer some good suggestions in regular code, but it tried really hard to understand your code, and went belly-up when it didn't.

At that time, I tried some other ML-based autocompletion tool which wasn't specific to python, and which usually worked much better, except that it used far too much memory and caused regular crashes.

Maybe they improved kite since I tried it, or maybe "individuals don't pay for dev tools" isn't the whole story. Or maybe both.

Anyway, kudos for both trying and for open-sourcing the code at the end!
