We put both tools through a month of real student work in October 2026: two assignments, a scholarship essay, forty emails and one very sloppy literature review. The roles split cleanly. Grammarly is a proofreader with opinions; QuillBot is a rephrasing engine with a thesaurus that has seen things. They overlap less than people assume, which is why the right answer for many students is both free tiers and zero rupees. This comparison covers where each wins, where each annoys, and the paid tiers that are actually worth it.

Quick answer
Grammarly checks and corrects your writing; QuillBot rewrites it. If your problem is errors, install Grammarly. If your problem is saying the same thing better, install QuillBot. Most students need Grammarly’s free tier first; QuillBot’s paraphraser becomes valuable the day you start producing drafts faster than you can rephrase them, and its free plan is unusually generous.
