Ask HN: Developer Tools that use AI?

I was wondering if people in HN know of any developer tools that use some kind of AI or ML behind the scenes to help out the developer. Are there tools like this in existence ? The only examples I have heard of is compiler optimization using ML ( but even that seems more research than reality as far as I know.).

Intellisense does not seem like an AI thing. So my question to HN is : Do you people know of any Developer Productivity Tools that use AI in some form or another ?
