QuillBot
- Synonym slider and modes (Formal, Academic, Simple) change how far the text moves from the original
- Premium at $8.33 per month billed annually covers paraphrasing, grammar, plagiarism and humanizing
- Chrome, Edge, Word and mobile keyboards keep it inside the place you write
- The free tier stops at 100 words per paraphrase, so a 300-word paragraph needs three passes
- Most modes and the history panel are locked behind Premium
The most complete tool built only for rewriting, and the one to start with.
ChatGPT
- You can state the exact change: shorter, plainer, more formal, aimed at a buyer
- Free plan has no fixed word cap per rewrite
- One tool for rewriting, outlining and fact-checking your own draft
- No built-in modes or synonym slider, so results depend on how well you write the instruction
- It can drift from the original meaning, so every output needs a read against the source
Best when the rewrite needs judgment, weakest when you want a quick one-click pass.
Wordtune
- Offers several rewrites for each sentence, so you pick the one that sounds like you
- Shorten and expand options change length without a new prompt
- Annual Advanced plan at $4.89 per month is the cheapest paid rewriter here
- The free Basic plan allows only 10 rewrites per day and 3 summaries per month
- Works sentence by sentence, which is slow on a long document
Great for emails and captions, tiring for a 2,000-word draft.
Grammarly
- Rewrites and tone suggestions appear in the apps you already use
- Pro adds full-sentence rewrites and tone adjustment on top of grammar checks
- Good at clarity and fluency problems that non-native writers hit often
- Paraphrasing is one feature among many, with less control than a dedicated rewriter
- Pro costs $12 per month billed annually and $30 month to month, the highest list price here
Choose it if proofreading is the main job and rewriting comes second.
Scribbr Paraphrasing Tool
- Free with no sign-up and no ads
- Accepts Word, Google Docs and PDF uploads
- Clickable thesaurus lets you swap single words in the output
- Inputs are capped at about 125 words, so longer text must be split
- Scribbr states the tool is powered by QuillBot, so you get a lighter version of the same engine
A clean free entry point, but QuillBot itself offers more.
Paraphraser.io
- Free tier accepts 400 to 600 words per input, the largest free limit in this list
- Five modes are free, including Formal and Smooth
- Paid plans start low and raise the limit to as much as 30,000 words
- The free page shows advertising, including a full-screen pop-up during our capture
- Creative, Shorten, Academic and Expand modes require a paid plan
Handy for long free rewrites, less pleasant to work in than the cleaner options.
Verdict
QuillBot wins for most people who search for a paraphrasing tool: it is the only option built entirely around rewriting, with a synonym slider, nine modes on Premium and a $8.33 monthly entry price. Pick ChatGPT when you need a specific tone or audience, Wordtune for sentence-level polish, Grammarly when proofreading comes first, and Scribbr or Paraphraser.io when you need a free pass without an account.
How we tested
This comparison is a desk review, not a lab test. On 26 October 2026 I read each tool's own plan and pricing pages, captured a screenshot of each interface at 1440 by 900 pixels, and checked free-tier limits, rewrite modes, supported surfaces and extras. I cross-checked user sentiment on Trustpilot and G2 where public scores exist. I did not run a controlled meaning-preservation test, so the scores from 0 to 5 weigh control, free-tier usefulness, price and fit for professional writing, and they will move when plans change. No tool here paid for placement, and none of the links on this page is an affiliate link.
Short answer. QuillBot is the best paraphrasing tool for most writers in 2026, because it is built only for rewriting and gives you a synonym slider, nine modes and a $8.33 monthly entry price on the annual plan. ChatGPT is the better choice when the job is a change of tone or audience, and Wordtune suits sentence-level polish. Scribbr and Paraphraser.io cover the free, no-account case.
You have a 300-word paragraph from a source and a deadline. The free version of one tool will take 100 words at a time, another 125, a third 400 or more. Before you compare quality, you are already comparing limits. That is where this list starts.
Which paraphrasing tool should you pick if you only try one?
The test that matters first is arithmetic, not style. A 300-word paragraph needs three passes in QuillBot's free tier (100 words each), three in Scribbr (about 125 each), and a single pass in Paraphraser.io, whose homepage counter showed a 400-word cap when I captured it. Wordtune's free Basic plan gives you 10 rewrites per day, which is plenty for emails and thin for a report.
QuillBot comes first because the limits are only part of the story. Its modes (Standard, Fluency, Formal, Academic, Simple and others) and the synonym slider let you decide how far the output moves from your source. Premium unlocks nine modes, custom modes, a history panel and full humanizing, and it bundles a plagiarism checker with 25,000 words per month. That matters if you paraphrase sources and need to check what you wrote.
Where QuillBot falls short
The free tier is the obvious limit: 100 words, two modes, no history. The second limit is easier to miss. A slider that swaps synonyms can leave sentence structure almost untouched, so a heavily "reworded" paragraph can still read like the original. Always compare the output to the source sentence by sentence.
Do you want a rewriting tool or a thinking partner?
ChatGPT sits second because it solves a different problem. A dedicated paraphraser changes words and structure. ChatGPT can change purpose: turn a technical paragraph into one a non-technical buyer would read, or cut a formal email to three lines. You describe the result, and it delivers it.
The price of that flexibility is control. There is no slider and no mode picker, so the quality of the output follows the quality of your instruction. It can also drift from the meaning of the source. Treat every output as a draft to check against the original, especially for academic paraphrasing where meaning must stay intact.
The practical split: use a dedicated paraphraser when the meaning is fixed and the wording must change, and use ChatGPT when the meaning itself needs adapting.
Sentence polish or document-level rewriting?
Wordtune and Grammarly both work close to the sentence. Wordtune offers several rewrites for each sentence and lets you shorten, expand or shift between casual and formal. On the annual plan, Advanced costs $4.89 per month and Unlimited $6.99, which makes it the cheapest paid rewriter in this list.
Grammarly's rewrite features sit inside a proofreading product. Pro adds full-sentence rewrites and tone adjustments, and it follows you into Gmail, Google Docs, LinkedIn and Notion. At $12 per month billed annually, or $30 month to month, you pay for that reach. The trade is control: Grammarly gives you fewer rewrite options than a dedicated paraphraser.
Customer sentiment splits along the same line. QuillBot shows about 4.8 on Trustpilot across more than 14,000 reviews and 4.3 on G2 from 34 reviews, and complaints centre on pricing and free-tier limits. Wordtune holds 4.1 on Trustpilot from 582 reviews. Grammarly sits at 3.1 from roughly 10,500 reviews, where the recurring complaint is billing and renewal, not rewriting quality. Read those numbers as signals about the company experience, not about paraphrasing accuracy.
Is a free paraphrasing tool enough?
For a one-off, yes, but there are two different kinds of free.
Scribbr's paraphraser is free, needs no sign-up and shows no ads. It accepts Word, Google Docs and PDF uploads and has a clickable thesaurus. Its own page says it is powered by QuillBot, and Scribbr's FAQ confirms that both services belong to Learneo. In practice you get the QuillBot engine with two modes and a cap of about 125 words per input.
Paraphraser.io takes the opposite trade. It accepts 400 to 600 words per input and offers five free modes, including Formal and Smooth, but the page carries advertising, and a full-screen advert covered the editor during my capture. Creative, Shorten, Academic and Expand need a paid plan.
If the text is private, read each tool's privacy terms before you paste it. A free web paraphraser sends your text to a server you do not control.
How to match the tool to the text
Five cases where the choice is clear, and the rule behind them: match the tool to the failure you are fixing.
A source paragraph you must restate in your own words: QuillBot with Academic or Fluency mode, then edit the result by hand.
An email that is too stiff or too casual: Wordtune or ChatGPT, because both change register.
A draft with grammar and clarity problems: Grammarly first, then a paraphraser only for the weak sentences.
A long passage, once, no account: Paraphraser.io, accepting the ads.
A short passage, once, no ads: Scribbr.
None of these tools replaces the check that matters. Paraphrasing a source without citing it is still plagiarism, and a rewrite that keeps the original sentence structure can still be flagged. Run a plagiarism check on anything you plan to submit, and cite the source.
What to do next
Start with QuillBot's free tier on one real paragraph. If you hit the 100-word cap in the first five minutes, that is your answer on whether Premium is worth $8.33 a month. If the output keeps the original structure, try the same paragraph in ChatGPT with an instruction such as "rewrite this for a reader with no technical background, same facts". Keep whichever result needs fewer manual edits, and stop there.
