I am searching for an alternative to the standard gboard. So far I found Fossify Keyboard, which was OK, but felt off somehow. I think it was the Fach, that it did not support a full Herman layout. Now I am testing Futo Keyboard. So far it is okay, but still not great. Are there and other options I should try? Also futo supports local ai models, but offers little support for German language. Is it also possible to run it with other ai models that are not in the Homepage? And are there and I could try?
