What's it actually like to use these tools day-to-day?
ChatGPT
ChatGPT is the Swiss Army knife of AI writing. It can draft a blog post, write a poem, debug your code, and brainstorm marketing copy — all in the same conversation. The quality is impressive but inconsistent; the best outputs come from users who've learned to prompt well. It's not perfect, but it's the default for a reason.
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.
