本当の違い
Grammarly offers a free tier while Sudowrite doesn't — that matters if you're bootstrapping.
Grammarly stands out with Real-time grammar, spelling, and punctuation corrections and Tone detection and rewrite suggestions. Sudowrite counters with Story engine for long-form fiction and Describe and expand tools.
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.
結論
If you value real-time grammar, spelling, and punctuation corrections and メール・ドキュメント・投稿を書く全ての人向け — どこでもミスをキャッチする常時オンのセーフティネット, go with Grammarly. If 物語構造と文体を本当に理解するai共著者が欲しいフィクション作家 matters more, Sudowrite is your pick. Neither is a bad choice — but one will fit your workflow better.
