I tried Tabnine and had mixed feelings. It can make sensible suggestions and save my time, but Tabnine forcing said suggestions to top priority means I’m spending time to press down key to find the obvious autocomplete. And this can’t be turned off.
Depending on your editor, this may/should be customisable. The tabnine client for Emacs (company-tabnine) is just another completion backend, and the order of completions presented is a just a variable in company-mode that can be set to any order you prefer[1].
Not sure about Kite though
