That depends. Does the plot involve one of the robots taking a bite out of the dessert planet?
Figure out a way to route all of your writing through your search engine, and have it flag phrases which do not occur in its database, or which occur much less frequently than similar ones. So, in this case, it would ask: "Did you mean 'desert planet'?"
Alternately, you could just have your secretary check everything before it goes out. You know, like they did in the old days. But then again, I still program in PL/I, and tie handwritten notes to the legs of pigeons.
Or, one could build a table of trigrams and bi-grams for English words and use that in the spell checker. It would be helpful to have some sort of approximate indexing, so you can catch things like 'dessert planet' which is just 1 edit step away from 'desert planet.'
I can see the advantage of a cloud-hosted solution here. It's getting pretty compute/memory intensive. Still, "spell/grammar" check is something that we'll probably never get completely right. We'll just peck away and approach asymptotically. Desert/dessert and their ilk are a worthy target. (Words that "look" right.)
My pigeons like to peck at things, and they seem to have success with that approach. We could probably learn something from them.
I wouldn't, as long as all of the extras can be toggled on/off. I'd actually pay a monthly fee for a search engine which has many features and is very customizable.
Even one that doesn't have "desert" in its dictionary?
Why can't the GP poster make an honest mistake, without others feeling the need to make excuses for them?
This puts the Candy Kingdom in the land of OOO in an entirely different perspective for me.
