There are many 'prediction' frameworks for emacs, I'm a bit puzzled as whether and how they integrate with one another.

I'm looking for something that learns words I type and predicts them. Also something that predicts org-mode syntacx. Maybe come C/C++ in the future.

I came across AutoComplete with auto complete for org-mode.
Then there is also predictive mode that appears to have an auto complete mode.

Now, does predictive mode actually make use of auto-complete, or is predictive's auto-complete different from the emacs/org-mode auto complete?

I.e, would I be able to configure predict mode to use autocomplete to auto-complete for org-mode?

In the mean time I got a reply form the author.

It seem that autocomplete and predictive mode are seperate entities.

No, predictive-mode uses the auto-completion-mode from the Completion-UI
library, which is in many ways significantly more powerful than
AutoComplete. (In particular, in ways that are useful for predictive
