Thanks for the suggestion. It supports multi-lingual typing which in a requirement for me. I haven't checked other keyboards for a long time so perhaps that has become more common.

The integration with whisper is nice too.

I don't find the multilingual features as polished as Gboard, this is what prevents me from switching, in Gboard you can install multiple languages and write without having to switch and it will provide autosuggestions and spelling support based on the language you're typing without having to manually change the language

Heliboard is another good one: https://github.com/Helium314/HeliBoard
