本当の違い
Both offer free tiers, so the real question is what you get when you start paying.
QuillBot stands out with Paraphrasing in 9 modes and Grammar checker. Wordtune counters with Sentence-level rewriting and Tone adjustment.
QuillBot's Achilles heel: paraphrasing can produce awkward phrasing — and the free tier’s 125-word limit is almost unusable. Wordtune's: works at sentence level, not document level — can’t write full articles or long-form content for you. Pick whichever weakness you can live with.
結論
If you value paraphrasing in 9 modes and パラフレーズ、文法チェック、剽窃検出を1つのツールで済ませたい学生や研究者, go with QuillBot. If ゼロから生成するより既存テキストを磨きたい非ネイティブ英語話者やプロフェッショナル matters more, Wordtune is your pick. Neither is a bad choice — but one will fit your workflow better.
