Summary
The most versatile AI writing tool available, capable of drafting, editing, brainstorming, and rewriting across virtually any format. It's the baseline every other tool gets compared to.

- Massive community of users sharing prompts and workflows
- Real-time grammar, spelling, and clarity suggestions across all platforms

Cons
- Can produce generic or verbose output without careful prompting

- Premium plan required for most AI and advanced style features
- Can over-correct and flatten natural writing voice
- AI generation features lag behind dedicated tools like ChatGPT
Our take
If you only use one AI writing tool, make it ChatGPT. It's the Swiss Army knife — not always the best at any single task, but nothing else handles the full range of writing needs as well.
Grammarly is the one tool that earns its keep even for people who write well. The real-time suggestions catch things you'd miss, and the AI rewrite features have gotten genuinely good.
