Grammarly vs QuillBot: Which Should You Choose in 2026?
Two content creation tools, compared feature by feature — pricing, ratings, strengths, and the use case each one wins.
The Short Answer
Both check for plagiarism and AI-generated text, so that is not the differentiator. QuillBot adds an AI Detector and a Humanizer that Grammarly's feature list does not include, and its Premium tier is cheaper. Grammarly adds team style guides and brand tones, and works natively inside browsers, MS Word, email and thousands of apps. QuillBot states outright that it is "not a from-scratch content generator." Grammarly for teams enforcing a consistent voice; QuillBot for rewriting and paraphrasing.

Grammarly
Pros
- Works natively across browsers, MS Word, email, and thousands of apps — no copy-paste workflow
- Best-in-class grammar, spelling, clarity, and tone suggestions that keep your own voice
- Generous permanent free plan covers spelling, grammar, tone, and 100 AI prompts/month
- Plagiarism and AI-text detection plus a citation generator built in
- Team features (shared style guide, brand tone, analytics) available on the affordable Pro tier
Cons
- Pro's headline $12/mo rate reflects annual billing; month-to-month is meaningfully pricier
- AI prompt allowance is capped (2,000/member/month on Pro) unlike unlimited-generation rivals
- Not built for long-form drafting or organizing large documents
- AI rewrites can strip a distinctive or creative voice if applied carelessly
- Enterprise pricing is hidden behind sales
- Real-time suggestions can feel intrusive for confident writers
QuillBot
Pros
- Genuinely useful permanent free plan that covers casual paraphrasing, grammar, and summarizing
- Premium is cheap at $8.33/mo billed annually versus most AI writing suites
- Strong for non-native speakers: paraphrase modes plus grammar and tone recommendations in one place
- All-in-one utility bundle (paraphraser, grammar, summarizer, plagiarism, AI detector, translator, citation)
- 6M+ user Chrome extension works across the web and Google Docs
Cons
- Not a from-scratch content generator like Jasper or Copy.ai; it reworks existing text
- Free tier is capped hard (125-word paraphrase, limited AI detector) so real use needs Premium
- Cheapest price requires an annual commitment; month-to-month is notably pricier
- Plagiarism checker is metered at 25,000 words/month even on Premium
- AI-humanizer and detector accuracy is inconsistent and shouldn't be relied on for compliance
- Device use is limited to 10 devices at a time
