QuillBot is the better paraphraser; Grammarly is the better all-round English editor. Which one wins depends on what you do most — and if you write across languages, neither may be the obvious pick. Here’s an honest, factual comparison.
What each does best
- QuillBot is paraphrasing-first: nine rewrite modes, a summarizer, and a translator. It’s the stronger choice if rephrasing and condensing are your daily tasks.
- Grammarly is an editing assistant: grammar, clarity, tone, and generative suggestions, with deep browser/desktop/Office integration. It’s stronger for polishing English prose across the apps you already use.
Languages
Both are English-first. Grammarly checks grammar in roughly six languages; QuillBot’s translator covers many, but its core paraphrasing/grammar strength is English and major European languages. If you write in Bahasa Indonesia, Javanese, Tagalog, Tamil, Swahili, Persian or Urdu, support thins out fast.
Free tier & price
- QuillBot free: ~125 words per paraphrase and 2 of 9 modes; Premium ≈ $9.95/mo monthly (cheaper annually).
- Grammarly free: grammar and spelling plus a limited number of AI prompts; Pro ≈ $12/mo annually.
