Grammarly
Grammarly is less of a writing tool and more of a writing safety net. It catches your typos, smooths your tone, and makes you sound more professional — all in the background. The generative AI features are a nice addition, but the core value is still 'make my writing not suck.' And at that, it's unbeatable.
