Checks the posts in your channel instead of your messages - add it as an admin and it reports typos in what you publish. English and Russian, free.
Every other bot here waits for you to paste a text. This one watches a channel: you add it as an administrator, run the setup command with the channel id, and from then on it reads what you publish and writes back about the typos it found. For a channel with several authors that is the difference between catching a mistake and hearing about it from readers.
Two checkers can be switched on independently, one for English and one for the Russian stop-word service glvrd.ru, so a bilingual channel does not have to pick. The price of the convenience is admin rights in the channel, which is a real decision rather than a formality - grant them only if you are comfortable with the bot reading every post you publish.
Free Free, and no paid plan is advertised.

No. It is built around channels you make it an administrator of; the direct chat is only used for setup and for its reports.
English, plus Russian through a separate check; each is switched on for the channel on its own. Posts in other languages are not covered.
