Auto-completing words in any program

Solution 1:

The Touch Bar integrates word prediction similar to iOS, which provides you with three word suggestions as you type. Tap a word to insert it. The more you type, the more the words filter. The screenshot shows when a new sentence is being started — type and the predictions finish your word.
