Is there an editor that can autocomplete texts of any reasonable length in a dictionary?

Question

Code completion

The task is to type texts of the same type in natural language (Russian, English) faster.
We feed the file to the editor:

Привет, как дела?
Привет, какого хрена тебе надо?
Какого хрена следовало бы намазать на бутерброд с колбасой?
Причём здесь хрен?

Further, when typing "When", he automatically offers "Hi, how are you?", Then with one button you can accept the proposed input or scroll to another option, which will be "Hi, what the hell do you need?" or another click on the third one, which will be "What the hell is this?" (the sequence may be different). When typing "how" the options are "how are you?", "what the hell do you want?", "What the hell should you put on a sausage sandwich?". Well, and so on ...
You need to supplement words, whole sentences, whole paragraphs and whole small texts of several paragraphs.
In principle, this can be relatively easy to program in some EMACS, but I wonder if there is a ready-made solution.
Thanks in advance.
