Grammarly

Grammarly is an AI-powered writing assistant that helps users improve grammar, spelling, clarity, style, and tone across browsers, desktop apps, and third-party integrations. The company offers solutions for individuals, enterprises, and educational institutions, and has expanded into generative AI writing with its GrammarlyGO product. It recently faced a lawsuit over its now-disabled "Expert Review" feature, which allegedly created AI-generated personas modeled on real writers without their consent.
