Quick answer

If English is your second language, the two tools help in different ways. Grammarly focuses on correcting and polishing what you have already written, and its Pro plan lists a feature called “Write fluently in English.” QuillBot is built around paraphrasing: rewording a sentence in a different style, such as simpler or more academic. It also offers a grammar checker and a translator. Both have free plans, so you can try each on your own writing first.

Free plans

  • Grammarly Free: spelling and grammar fixes, writing tone detection, and 100 AI prompts per month.
  • QuillBot Free: paraphrasing up to 100 words at a time in 2 modes, basic grammar fixes, and basic summaries.
  • Grammarly Pro: $30/month, or $144/year billed annually ($12/month on average), with a free trial. Pro adds full-sentence rewrites, tone adjustment, “Write fluently in English,” unlimited personalized suggestions, plagiarism and AI-text detection, and 2,000 AI prompts per month.
  • QuillBot Premium: $19.95/month, or $8.33/month billed annually. Premium adds unlimited paraphrasing modes, advanced grammar suggestions, full use of the AI detector, and plagiarism checking.

What matters if English isn’t your first language

  • Fixing vs rewording. Grammarly’s suggestions are designed around the text you already wrote. QuillBot’s paraphraser offers alternative wordings of a whole sentence. That can help when your sentence is grammatical but sounds unnatural.
  • Style modes. QuillBot lists 10+ paraphrasing modes, from Academic to Simple. On the Free plan you get 2.
  • Translation. QuillBot’s tool menu includes a translator, which can help if you draft in your own language first.
  • Rules where you write. Schools and some employers have policies on AI writing and paraphrasing tools. Check them before you use either tool for graded or official work.

Which should you choose?

  • Look at Grammarly if you mainly want your own writing corrected and polished as you type.
  • Look at QuillBot if you often need a sentence reworded in a simpler or more formal style.
