It's too unpolished yet to present it to the public. For example it tries to change tenses unnecessarily or guesses wrong pronouns with obvious clues.

But I support this project. Grammarly is too rigid in its suggestions despite being pretty mature. Jasper has a shitty webapp with obligatory signin and strange behaviour. And Sudowrite was unusable in my attempt because it didn't make my sample sentences any better despite wanting $20 a month.
