Grammarly vs QuillBot for Paraphrasing 2026
This is not a close contest. QuillBot is a dedicated paraphrasing engine built specifically to reword, rewrite, and restructure text — it has eight distinct paraphrase modes, a 125-word free tier with unlimited uses, and a Premium plan that removes all word limits. Grammarly is an always-on writing assistant that catches grammar and style errors in real time. It can suggest rewrites for individual sentences via AI prompts, but paraphrasing is a feature bolted onto a broader tool, not the core product. If paraphrasing is your primary task, this verdict is clear before you even read the details.
The AI Map Verdict — June 2026
For paraphrasing: QuillBot wins by a wide margin. It is the dedicated tool. Grammarly is not.
QuillBot has 8 purpose-built paraphrase modes (Standard, Fluency, Formal, Academic, Simple, Creative, Expand, Shorten). Its free tier gives you 125 words per paraphrase with unlimited uses — enough for most sentences and short passages. Premium at $9.99/month removes the word limit entirely. Grammarly has one basic rewrite suggestion accessible via AI prompts. It is not designed for paraphrasing and should not be your tool for this task.
Quick Answer — Last verified: June 2026
Use QuillBot for paraphrasing. The free tier (125 words/paraphrase, unlimited uses, Standard + Fluency modes) is enough for most tasks at $0. Upgrade to QuillBot Premium ($9.99/mo) for unlimited word length and access to all 8 modes including Academic and Formal. Grammarly is not a paraphrasing tool — it can rewrite individual sentences but has no dedicated paraphrase modes and requires using AI prompt credits to do it.

Use Case Verdicts
Paraphrasing research sources for essays or reports
→ QuillBot wins
QuillBot's Academic mode rewrites source material in proper academic register — precise vocabulary, formal sentence structure, passive constructions where appropriate. You paste in a passage from a journal article, select Academic mode, and get a version you can incorporate into your essay. The free tier (125 words, unlimited uses) covers most individual citations. Grammarly has no equivalent — you can ask it to rewrite a sentence via AI prompts but it has no academic register control.
Rewriting content to avoid duplicate content issues
→ QuillBot wins
Content writers who need to rewrite existing material — for different publications, to refresh old posts, or to produce variations — need a tool that changes phrasing significantly enough to be considered unique. QuillBot's Creative and Standard modes produce substantively different rewrites that change sentence structure and vocabulary together. Grammarly's sentence rewrites are lighter edits — they improve clarity but are not designed to substantially transform content.
Making text more formal for business or professional use
→ QuillBot wins
QuillBot's Formal mode systematically removes contractions, casual vocabulary, and colloquialisms — turning informal writing into professional-register text. Grammarly detects informal tone and flags it, but it does not rewrite your text into formal register automatically. You would need to manually accept individual suggestions, which is a much slower workflow than selecting Formal mode and paraphrasing a block of text in one action.
Simplifying complex text for a general audience
→ QuillBot wins
QuillBot's Simple mode breaks down complex vocabulary and restructures sentences for readability — useful for anyone writing technical content for non-expert audiences, producing explainer content, or adapting documentation for end users. Grammarly has a clarity score and flags complex sentences, but it does not paraphrase them into simpler language — it asks you to make the changes yourself.
Paraphrasing a long document (1,000+ words)
→ QuillBot Premium wins
QuillBot's free tier limits you to 125 words per paraphrase — you can run it unlimited times but must break long documents into chunks manually. For longer-form paraphrasing tasks, QuillBot Premium ($9.99/month) removes this limit entirely and lets you process large blocks of text in one pass. Grammarly has no equivalent — its AI prompt rewrites are sentence-by-sentence and consume prompt credits from a monthly allowance.
Real-time writing correction while you paraphrase
→ Grammarly wins
Grammarly works live inside Google Docs and Word — it catches grammar, spelling, and tone errors as you type your paraphrased text back into your document. QuillBot's Chrome extension has some inline features, but Grammarly's live correction is significantly more seamless. The practical workflow many writers use: QuillBot for the paraphrasing step, Grammarly for catching errors in the output as it gets written into the document.
The workflow that combines both: Open QuillBot in one tab. Write your draft in Google Docs with Grammarly's extension active. When you need to paraphrase a source, paste into QuillBot, select the right mode, copy the output, and paste it back into your document. Grammarly catches any errors in the paraphrased output as you write. Both free tiers support this at $0.

Frequently Asked Questions
Is QuillBot better than Grammarly for paraphrasing?
Yes — by a significant margin. QuillBot is a dedicated paraphrasing tool with 8 purpose-built modes (Standard, Fluency, Formal, Academic, Simple, Creative, Expand, Shorten). Grammarly has no dedicated paraphrase modes — it can rewrite individual sentences via AI prompts but this is a secondary feature of a broader writing assistant. For paraphrasing as a primary task, use QuillBot.
Can Grammarly paraphrase text?
Grammarly can suggest rewrites for individual sentences via its AI prompts feature. On the free tier you get 100 AI prompts per month — you can use these to ask Grammarly to rewrite a sentence. However, Grammarly has no dedicated paraphrase modes, no word-level synonym swapping, no tone slider, and no Academic or Formal register modes. For occasional sentence-level rewrites it works, but it is not a substitute for QuillBot if paraphrasing is a regular part of your workflow.
What is QuillBot's best paraphrase mode for essays?
Academic mode — it rewrites text in formal academic register with precise vocabulary and appropriate sentence structures for scholarly writing. It is a Premium feature ($9.99/month). For free-tier users, Standard mode produces a neutral rewrite that can be adapted for essays, though it is less targeted to academic conventions. Fluency mode is best if the source text has grammar issues that need fixing alongside the paraphrase.
Does QuillBot paraphrasing avoid plagiarism?
QuillBot's paraphraser changes phrasing and vocabulary, which can help you incorporate source material without copying it verbatim. However, paraphrasing does not automatically make content plagiarism-free — you must still cite the original source even when paraphrasing. QuillBot Premium also includes a separate plagiarism checker (25,000 words/month) to help you verify your own work before submitting. Always cite sources regardless of how thoroughly you paraphrase.
Can I use QuillBot for free for paraphrasing?
Yes. QuillBot's free tier lets you paraphrase up to 125 words per input with unlimited uses — no account required to try it. You get 2 modes: Standard and Fluency. For most individual sentences and short passages this is sufficient. The 125-word limit means you need to break longer texts into chunks. Premium ($9.99/month) removes the word limit entirely and unlocks all 8 modes.
Which QuillBot paraphrase modes are free?
Standard and Fluency modes are included on the free tier. All other modes — Formal, Academic, Simple, Creative, Expand, and Shorten — require QuillBot Premium. The free Standard mode is suitable for most general paraphrasing. Fluency mode on the free tier is especially useful for non-native English writers as it fixes grammatical awkwardness while paraphrasing.
