The Verdict
Grammarly is built for writers and students, with a focus on grammar and spelling. QuillBot targets students and academics and leads with paraphrasing and grammar-check.
Pricing is close: QuillBot starts at $9.95/mo versus $12/mo for Grammarly — not a deciding factor on its own.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, QuillBot offers broader built-in capabilities (7 features vs 6), while Grammarly takes a more focused approach — which can mean a simpler, faster onboarding experience.
Both tools are a solid fit for writers, students, non native speakers — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
