Spell check

This is the small, boring tool the subtopic needs and rarely has - a checker that does one job in two languages and asks nothing in return. Its own profile describes it in English and Russian alike, so it is not a Russian bot with an English label.

There is no account, no menu and no paid tier advertised anywhere on its page or in the catalogs that list it. Because of that there is also no support desk and no promise of uptime, so use it as a second pair of eyes on a message rather than as a step in a publishing workflow.
