Grammarly earns its place by being everywhere you write, quietly improving grammar, clarity, and tone without changing your workflow. It is an assistant, not a generator.
Monica's insight is that the assistant should come to the page rather than the other way round. Highlight anything on the web and a sidebar can explain, translate or rewrite it, with several frontier models a dropdown apart. That model choice is the real differentiator: you can sanity-check one model's answer against another without leaving the tab. It trades depth for breadth, so power users still keep a dedicated assistant alongside it.
