An open-source bot that sits in a chat and replies to messages with spelling corrections, in English and Spanish. Free, MIT-licensed, and the only Spanish checker here.
This is the group-chat kind of checker rather than the paste-a-text kind. It reads the messages sent in a chat it has been added to and answers with the corrections it found, which makes it a tool a group agrees to rather than one person uses. Its Telegram page links the author's Twitter account, but the project itself is a public repository under an MIT licence, so the code and the analyzer it calls can be read rather than guessed at.
It covers English and Spanish, and Spanish is the reason it is here - almost every other bot in this subtopic handles Russian, English or French and stops. Like any open-source side project it comes with no support desk, and in a busy chat a bot that comments on typos wears out its welcome fast, so turn it on where people asked for it.
Free Free and open source, with no paid plan advertised.

No. The names are alike, but this one is the open-source project for English and Spanish, while @GrammarNaziBot handles Russian and English.
Yes. The project is published under an MIT licence, so a self-hosted instance for your own chat is allowed.
