What's it actually like to use these tools day-to-day?
Writesonic
Writesonic tries to be the all-in-one AI content platform, and it does a decent job. The SEO article writer is probably its strongest suit, and the Chatsonic chatbot is a nice bonus. It's not the best at any single thing, but it's competent across the board at a reasonable price.
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.
