I would really like to be able to entirely disable spell checking. I know it's a very niche desire, but I'm happy to live with my mistakes, and there are regularly bits of slang, technical terms, acronyms etc that I have to get it to "learn" which I'd rather not have to. I often wonder how people who write in non-standard English manage these days. Can't imagine James Joyce would have been a fan.

What's stopping you? I have spekl check disabled on all my devices.

And I'm not even a native speaker, so I would certainly benefit, but like you I hate when it complains (or autocorrects!) intentional strings.

Obviously :-)

I've tried on MacOS and can't seem to figure out how to do it. I seem to be able to on certain apps, but there isn't a global kill switch, which is what I want.

MS Word has a "check spelling as you type" option which can be turned off - same with grammar.
