Spelling checkers aren't much use, I find they make more mistakes than I do. I don't make many spelling mistakes, but I do make typos when I am in a hurry. I can't touch-type, so I look at the keyboard rather than the screen, and just glance up at it when I finish typing - typos then jump out at me and can be corrected (or not, if I am in a hurry).
That works OK on the desktop machine, but since I got a Kindle Fire with Android-type spellchecker and often post on that, I have had it come up (in a post about " girly swots" and public schoolboys) with some weird things.
For "single-sex" schools it thought I wanted to type "anti-war"
for "clever" it wanted "forces"
and for "swot" it wanted "can't"
Am I being censored? Is big brother BJ reading my posts?
