Uses user data for AI training
On their main page they advertise in big font “This is responsible AI… We do not allow our third party service providers to train their models on user content.” This makes you think your content is not used for any AI training. WRONG! When you go into settings you see an option for “Product Improvement and Training" enabled by default: “Allow Grammarly to train its models and improve its product for everyone by using your content.” DESPITE ADVERTISING they don’t do this, they do it. Are they talking about 3rd-party training vs. 1st party? Yes. Does that distinction matter to most people? No! If you advertise yourself as "responsible AI" and state no training, what that should mean is you don’t give user content to others to train on OR use it yourself for training, especially without telling the user. Oh, and by the way, their product on Microsoft Word is unusably laggy. And somehow in their web app its even worse (on large documents anwyay).
