I’ve been playing with both the Thumb and the Unexpected keyboards. I like 'em both but, man, I have to admit I’d like them more if they had that top bar that predicts what you might be. Is that just a no-go from a privacy perspective? Can that functionality be local?
(I also wouldn’t mind a good voice typing feature)
If you are talking about Android keyboard, is https://github.com/helium314/openboard not a good option?
Updated 18 months ago on F-Droid, but the Github looks still active. I hope they’ll soon have a releasable version.
The project linked is a fork of the version on F-Driod. You can download the APK directly from the Github and use it just fine.
My only problem with it is, that it removes the currently typed word from the autocomplete bar.
