I'm using heliboard at the moment. They offer swipe typing through the Google libraries currently. But are exploring a data collection process completely voluntarily to build their own swipe typing libraries.

I did like futo's voice typing input method. It's recognition was generally right up there with Google's. Although there were certain words it frustratingly and consistently got wrong no matter how specifically I said them. But the fact that it could infer punctuation rather accurately where Google won't even try was definitely nice. Unfortunately I have not found a truly viable replacement for that sort of input yet. I definitely believe that sometime in the not-too-distant future there will absolutely be a Foss local solution. But I don't believe that futo's solution is trustworthy enough to believe that it was local Etc.
