I use Zeal. Local. Opensource. Uses Dash's docsets. Has basic integration with Sublime.

I have a feeling lot of the functionality of Kite will eventually get into Zeal type local tools.

Which component of Zeal allows you to pull in your own local code for completion?

Zeal definitely works great for popular third party library code and integrates with Sublime, but I haven't seen options for it to integrate with your own libraries or third party libraries that aren't quite big enough to be supported by Zeal directly.
