Here’s my lazy and unpopular solution

I use OpenBoard. It’s good, but my only problem is the lack of images being copied to the clipboard unlike my default keyboard.

I use openboard but it gets me mad sometimes when I start deleting characters and it removes the space between the last word…sometimes it’s really annoying!

Privacy respecting, but not open source:

Typewise

(Also a lot less typos and faster writing once you get used to it.)

I use Gboard but with internet access disabled for it. I haven’t found a comparable open source keyboard yet.

I use FlorisBoard. It’s not perfect, but it has a fully featured clipboard and undo-redo functionality. Missing the swipe tho.

Try Thumb-Key. It’s a keyboard made by Lemmy’s main developer. It uses a rather exotic layout, but once you get used to it, it is so much better than qwerty.
