That would be a grammar checker though. And there are many solutions available today to do that. Even open source solutions. Grammarly would be one example, language tool another.

The ones I looked at work by encoding common spelling mistakes into a grammar (as in Chomsky grammar) and then running that over the text.

No, that's not grammar checking, but spelling mistakes that turn out to be real words!

If you misspelled "college" as "collage", or you misspelled "three" as "tree" the word you typed incorrectly happens to be an actual word itself! Correcting these types of errors is called "real word spelling correction".

Real-word spelling errors are words in a text that, although correctly spelled words in the dictionary, are not the words that the writer intended

And even if there are several approaches evaluated, the problem is far from solved.

It's so weird that spellchecking isn't context sensitive: both locality and use.

Locality: The pair "buy Apple" must be vastly preferred, like millions of times more.

Use: I'm writing this and my swipe keyboard offers "spellcasting" when I want "spellchecking". The page I'm on is about spellchecking and the other word isn't one I've ever used until now. You can split these down in to prior-use and use-context, I guess: the former is most annoying, always having to correct in the same manner.
