I don’t think the default keyboard is all that bad after using the Apple default keyboard for over a year! I honestly find the default Samsung keyboard to be more accurate with autocorrect choices and spellings. I just hate the fact their LLM button cannot be removed from the keyboard layout, as all other buttons are editable.

I ended up using Typewise which is a fairly competent keyboard that you can set to be offline or without the smelly OpenAI integration (I missed that detail about them).
