本当の違い
Both offer free tiers, so the real question is what you get when you start paying.
ChatGPT stands out with Conversational AI writing and Custom GPTs. QuillBot counters with Paraphrasing in 9 modes and Grammar checker.
ChatGPT's Achilles heel: not purpose-built for marketing — no brand voice, no templates, no team workflow. you have to prompt-engineer everything yourself. QuillBot's: paraphrasing can produce awkward phrasing — and the free tier’s 125-word limit is almost unusable. Pick whichever weakness you can live with.
