Hey there, I'm Alex, founder of Linguix.com writing assistant.
We’ve recently released AI grammar checker and Rewriter add-in: https://miro.com/marketplace/grammar-checker-rewriter/
It works in English :flag_gb:, French :flag_fr:, German :flag_de:, Spanish :flag_es:, Portuguese :flag_pt:, and Polish :flag_pl:.
Our app can fix your typos and grammar mistakes + rewrite whole sentences. Another cool feature is a content quality score that you can use to understand when the content is good to publish.
I appreciate any feedback. Just dm me or email directly at alex@linguix.com
