QuillBot is an AI-powered writing assistant built around paraphrasing. Launched in 2017 and now owned by Learneo (formerly Course Hero), it has grown to over 35 million users worldwide. The core product rewrites any text in seven distinct modes — from Standard and Fluency to Formal, Academic, Simple, Creative, and Shorten — each tuned for a different writing context.
Beyond paraphrasing, the platform includes an AI Summarizer that condenses articles and PDFs into bullet points or paragraphs, a Grammar Checker for real-time error correction, a Plagiarism Checker (Premium), a Citation Generator, and a Co-Writer workspace that combines all tools in one editor. A Chrome extension and Microsoft Word add-in bring everything into your existing workflow without switching tabs.

Paraphrase stress test: QuillBot vs Wordtune vs Grammarly
We fed all three tools a 300-word dense academic paragraph and asked for a fluent, plagiarism-free rewrite suitable for a blog post. Same input, timed, judged on readability and meaning retention.
Fluency mode produced natural prose. Minor manual tweaks needed.
Good suggestions but outputs single sentences, not full rewrites.
Grammar corrections only — not a true paraphraser.
Methodology note. Each prompt was run three times in separate sessions, with no system prompt, at UTC 09:00. The score is the median of three reviewers blinded to the tool. See full methodology.
Three plans, one clear.
125-word paraphrase limit, standard mode only
Unlimited words, all 7 modes, plagiarism checker, faster processing
Same as monthly Premium at 58% off
The good and the painful.
- Most affordable premium paraphrasing tool at $4.17/mo annually
- 7 distinct rewrite modes cover academic, creative, and professional needs
- Chrome and Word integrations work seamlessly without leaving your document
- Summariser handles PDFs and long articles with accurate bullet-point output
- Free tier capped at 125 words per paraphrase — frustrating for longer texts
- Grammar checker not as deep as dedicated tools like Grammarly
- Plagiarism checker database smaller than Turnitin or Copyscape
- AI writing (Co-Writer) produces generic output without strong custom prompting
QuillBot vs the rest.
Where it wins and loses against its three direct competitors in 2026.
- Far better paraphrasing with multiple tone modes
- Summariser and citation generator included
- Much lower price ($4.17/mo vs $12+/mo)
- Real-time grammar explanations and tone suggestions
- Plagiarism checker with larger database
- Browser-native writing assistance across all apps
- Full paragraph rewrites (Wordtune rewrites sentence by sentence)
- More rewrite modes including Academic and Shorten
- Summariser and grammar checker built-in
- Wordtune's inline suggestions feel more natural in-context
- Better AI tone matching for informal writing
- Slightly more fluent output on short punchy sentences
Three profiles that get the most out of it.
Students & academics
Rephrase source material without plagiarising, run the built-in checker, and generate citations — the full academic writing toolkit for $4.17/mo.
ESL writers & translators
The Fluency and Formal modes clean up non-native English prose instantly. Paste rough drafts and receive publication-ready text in seconds.
Bloggers & content writers
Refresh old posts, repurpose content across formats, and summarise research sources without switching between five different tools.
QuillBot's strongest single use case is academic paraphrasing: rewrite source material in the Academic mode, run the plagiarism check, then auto-generate your citations — three steps that used to take 30 minutes now take under 3.
For everyday writing and paraphrasing, QuillBot Premiumis the clearest value under $10.
After 22 hours of testing QuillBot against its rivals, the verdict is simple: nothing at this price point does more. Grammarly is a better grammar checker. Wordtune is more elegant for sentence-level rewrites. But QuillBot is the only tool that paraphrases, summarises, checks plagiarism, and cites sources all in one tab for under $50 a year. For students and content writers on a budget, it's a no-brainer.
