本当の違い
Rytr offers a free tier while Sudowrite doesn't — that matters if you're bootstrapping.
Rytr stands out with 40+ use cases and 20+ tone options. Sudowrite counters with Story engine for long-form fiction and Describe and expand tools.
Rytr's Achilles heel: output quality is noticeably lower than jasper or chatgpt — works for short copy but struggles with nuance. Sudowrite's: fiction-only niche — completely useless for marketing copy, blog posts, or business writing. Pick whichever weakness you can live with.
