If you use the privacy respecting Gboard alternative called FUTO keyboard, you’ve probably noticed that the built in swipe typing is HOT GARBAGE. (Typing this currently with two thumbs for this exact reason.)
Most keyboards improve their swipe algorithms by simply spying on you and logging your typing data. FUTO isn’t about that, so they have built a simple webpage based typing game that you can use to improve their system in an ethical and voluntary manner! Just swipe the website’s keyboard to type a provided sentence.
I love this, they can crowdsource the improvement without invading privacy!
Does not have swipe except when using a Google library
The Google library is fully offline as far as everyone knows. Sure it’s a binary blob and projects such as this linked here aim to finally break free from that dependency. But for the time being, I’ll be Ok with that offline blob until this futo becomes a viable alternative.
