I initially tried FUTO and switched to Heliboard (which uses a closed-source glide typing library) because FUTO’s open-source version frankly sucked.

I didn’t know I could make it better.

It takes a lot of time and a lot of peoples typing data from my understanding. It’s relatively easy for Google to make the glide/Swype type since they have a huge amount of peoples typing data. FUTO on the other hand has been making an open source version for probably 6 months or so no, solely relying on volunteers inputting words on their website.

For those interested in helping make the library better: https://swype.futo.org/ (it probably only works on mobile)
