Grammarly vs QuillBot: the premium writing assistant against the free paraphrasing tool. They overlap, but serve different needs.
Quick Verdict
Grammarly wins for: comprehensive writing improvement, tone detection, universal availability, and professional use.
QuillBot wins for: paraphrasing, affordability, academic writing, and budget-conscious users.
Grammar and Corrections
Grammarly is more thorough. It catches nuanced grammar issues, suggests clarity improvements, and detects tone mismatches. QuillBot handles basic grammar but focuses more on paraphrasing than comprehensive writing analysis.
Winner: Grammarly
Paraphrasing
QuillBot’s paraphraser is its core strength. It offers multiple modes (Standard, Fluency, Formal, Simple, Creative, Expand, Shorten) and handles paraphrasing with more nuance and control than Grammarly’s rewrite suggestions.
Winner: QuillBot
Tone and Style
Grammarly’s tone detector shows how your writing will be perceived — confident, friendly, formal, etc. It suggests adjustments to match your intended tone. QuillBot offers tone modes in paraphrasing but lacks ongoing tone analysis.
Winner: Grammarly
Platform Coverage
Grammarly works everywhere: browser extension, desktop app, mobile keyboard, Office integration, Slack, and more. QuillBot has a browser extension and web app but significantly less platform coverage.
Winner: Grammarly
Academic Use
QuillBot’s combination of paraphrasing and citation generation is popular with students and academics. Grammarly’s plagiarism checker is useful for academia, but QuillBot’s paraphrasing tools are more directly helpful for academic writing.
Winner: QuillBot
Pricing
