真正的区别
Grammarly offers a free tier while Sudowrite doesn't — that matters if you're bootstrapping.

Grammarly's Achilles heel: suggestions can be overly conservative and strip personality from your writing if you accept everything blindly. Sudowrite's: fiction-only niche — completely useless for marketing copy, blog posts, or business writing. Pick whichever weakness you can live with.
