★★★★★Trustpilot · November 2026
Reviewer says paraphrasing is accurate and the grammar checker spots subtle errors; used daily for emails, essays and work.
We ran 20 passages through QuillBot over a week and had three judges, who didn't know which tool wrote what, check the results. It kept the original meaning in 16 of the 20 passages, made 1.1 errors per 1,000 words and scored 4.0 out of 5 for readability. That earned it 4 out of 5 overall and 2nd place of the 6 AI paraphrasing tools we tested the same way.
The main finding is that QuillBot is a solid, all-round rewriter. Its rewrites read well and usually say what the original said, and it comes with a grammar checker, summarizer, translator and plagiarism checker. Its weak spot is that 4 of our 20 passages drifted in meaning, so you still need to read what it gives you.
QuillBot suits students and writers who want one tool to reword and tidy their text. The free plan is fine for short pieces, and Premium costs $4.17 a month, billed yearly.
How we scored it
QuillBot scored 4 out of 5 overall. Ease of use was its best part at 4.5, and features and limits its weakest at 3. None stood out as a problem, and each fell short of top marks for its own reason.

- Value for money (4/5): Premium is cheap at $4.17 a month billed yearly, but the monthly price isn't shown on the default pricing view.

The best AI paraphrasing tools
Before you pick QuillBot, see how all 6 tools ranked in the same test.
QuillBot in plain terms
QuillBot is an AI paraphrasing tool. You paste in some text and it rewrites it in a different way, keeping the meaning but changing the words and sentence structure. You choose a mode, such as Standard or Fluency, to decide how much it changes and in what style.
It also bundles other writing tools in one place: a grammar checker, a summarizer, a translator, an AI detector, a humanizer and a plagiarism checker. That's what sets it apart from simpler AI writing tools that only swap words. QuillBot is owned by Learneo, formerly Course Hero, which bought it in August 2021 and also owns LanguageTool and Scribbr.
QuillBot rewrites whole passages in modes, while some rivals, such as Wordtune, suggest changes one sentence at a time inside your editor. It is aimed mainly at students and everyday writers who want to reword or tidy text.
What happens after you sign up
QuillBot works in your browser or through its Chrome extension, and a rewrite takes four steps.
1. Paste your text. Put your text into the paraphraser box or upload it. On the free plan, each rewrite is capped at 125 words.
2. Pick a mode. Choose Standard or Fluency for free, or one of the extra modes on Premium.
3. Rewrite and adjust. QuillBot rewrites the text, and you can click on words to swap in synonyms you prefer.
4. Polish it. Run the grammar checker, summarizer or plagiarism checker on the result, all from the same account.
What you get
QuillBot's main tool is the paraphraser, but the extra tools are a big part of its value. Free users get a taste of most of them, and Premium removes the limits.
Paraphraser
Rewrites text in selectable modes. Free gives you 2 modes and 125 words per use, while Premium opens 9 or more modes with no word limit.
Summarizer
Shortens long text into key points or a paragraph. Free handles 1,200 words at a time, and Premium 6,000.
Translator
Translates text, up to 5,000 characters on the free plan and without a limit on Premium.
Plagiarism checker
Checks your text against other sources, so you can spot passages that are too close to the original. It's on Premium, with 25,000 words a month.
Compare modes and history
On Premium, see several modes side by side and go back to past rewrites, which helps when you're choosing the best version.
Grammar, AI detector and humanizer
Basic grammar checks and a limited AI detector and humanizer are free. Premium adds advanced grammar and the full versions.
Who gets the most out of QuillBot
QuillBot is a good everyday rewriter for people who write a lot of short to medium text. It is less suited to anyone who needs long rewrites for free or wants guarantees about how their text is handled.
A good fit for
- Students rewording and tidying essay drafts
- Non-native writers who want clearer phrasing
- Writers who want rewording, grammar and summaries in one tool
- People on a budget happy to pay yearly
Not a good fit for
- Anyone who needs long rewrites for free
- People who want a refund after the first 3 days
- Writers who can't afford any change in meaning
- Anyone pasting confidential client text without checking the privacy policy
QuillBot vs Ahrefs Paraphrasing Tool, Wordtune and rewriting by hand
The Ahrefs Paraphrasing Tool beat QuillBot in our test with 5 out of 5. It's a free sentence-level tool, so for short rewrites it's hard to argue with. QuillBot pulls ahead when you want more modes, longer rewrites and the extra tools. Wordtune came 3rd with 3 out of 5 and starts at $6.99 a month.
Rewriting by hand is free and keeps you in full control of the meaning, but it is slow. QuillBot is much faster, and in our test it kept the meaning of 16 of 20 passages. That's good, but it means you still need to read every rewrite before you use it. Our best paraphrasing tools list compares all six.
| Option | Price | How it compares |
|---|---|---|
| QuillBot | Free, or $4.17 a month billed yearly | Rewrites whole passages in modes, with grammar, summary, translation and plagiarism tools. |
| Ahrefs Paraphrasing Tool | Free | A free sentence-level rewording tool from an SEO software company. |
| Wordtune | Free, or $6.99 a month | Suggests sentence rewrites inside your editor as you type. |
| Rewriting by hand | Free | You reword the text yourself, which is slow but keeps you in full control. |
Our 7-day QuillBot test
We tested QuillBot from October 21 to October 27, 2026, 7 days in all. Every paraphrasing tool in our group got the same 20 passages to rewrite. The full method is in how we test.
For each passage, we checked three things. Did the rewrite still mean the same thing as the original? How easy was it to read? And how many errors did it introduce? Three judges scored the rewrites blind, so they didn't know which tool had written which version.
QuillBot kept the meaning in 16 of the 20 passages. In the other 4, the rewrite drifted far enough from the original that a reader would come away with a different idea. That's the main thing to watch with any paraphraser, and QuillBot did better than most here.
It made 1.1 errors per 1,000 words, which is low. In practice, you'd expect to fix one or two small mistakes in a long essay, not rewrite sections.
Our judges gave its rewrites 4.0 out of 5 for readability. The text read naturally and didn't feel like it had been put through a word-swapping machine, which surprised us a little at the price.
| What we measured | Result | What it means |
|---|---|---|
| Passages where the rewrite kept the original meaning | Meanings preserved: 16/20 | Most rewrites say the same thing, but about one in five drifts, so always read the result. |
| Errors introduced per 1,000 words | 1.1 errors/1,000 words | Expect only a small number of mistakes to fix in a long piece of writing. |
| Blind readability score from three judges | 4.0/5; three blind judges | The rewrites read naturally enough to use with light editing. |
QuillBot did well across the board. It kept the meaning of most passages, introduced few errors and produced text our judges found easy to read. It wasn't perfect: 4 of 20 rewrites drifted in meaning, which is why it scored 4 rather than 5. But for a low-cost tool with a free plan, it's a dependable everyday rewriter.
Tested October 21, 2026 to October 27, 2026.
The good and the bad from our test
Rewrites read naturally
Our three blind judges gave QuillBot 4.0 out of 5 for readability. The rewrites sounded like normal writing, so you can use them with light editing.
Few errors
It made just 1.1 errors per 1,000 words. That's a handful of small fixes in a long essay, not a full rewrite.
Lots of tools for a low price
Premium costs $4.17 a month, billed yearly, and adds 9 or more modes, advanced grammar, a plagiarism checker and longer summaries. That's a lot of writing help for the price.
Some rewrites changed the meaning
4 of our 20 passages drifted from the original meaning. For essays or work documents, that means reading every rewrite before you use it.
Tight free limits
The free plan caps each rewrite at 125 words and gives you only 2 modes, with no plagiarism checker. Longer text has to be split up.
Short refund window
There's no free trial, just a 3-day money-back guarantee on a first purchase made on QuillBot.com. Renewals aren't refundable unless the law requires it.

Is QuillBot safe to use for your writing?
QuillBot handles whatever text you paste into it. We couldn't read its terms or privacy policy, so we can't tell you whether your text is stored or used to train its AI. That doesn't mean there's a problem, but it's worth checking before you paste anything sensitive.
We found no reported security incidents. QuillBot is owned by Learneo, the company behind Course Hero, which also owns LanguageTool and Scribbr.
If you're a student, check your school's rules before using any paraphraser on graded work. Rewording someone else's text doesn't make it your own, and many schools treat it as a breach of their integrity rules.
Don't paste confidential or unpublished client text until you've read the privacy policy yourself.

Recent user reviews, in short
Summarised in our own words, not quoted. Reviewer names are left out.
★★★★★Trustpilot · November 2026
Reviewer likes the tool but hopes it stays free because payment methods are hard to get in Algeria.
★★★★★Trustpilot · November 2026
Student-focused reviewer recommends it for academic writing, paraphrasing and translation.
★★★★★Trustpilot · November 2026
Subscriber says they would not want to give up the subscription because it works well.
Our test broadly agrees with users. QuillBot's rewrites read well and kept the meaning most of the time. But where users describe it as accurate, our test found 4 of 20 passages drifted, so we'd still read every rewrite rather than trust it blindly.

QuillBot alternatives worth a look
QuillBot came 2nd of the 6 paraphrasing tools we tested. Here's how the others compared in the same test.

ReWrite It.AI
ReWrite It.AI scored 3 out of 5, with weaker output quality and value than QuillBot. We couldn't find its prices, so check before you sign up.

4/5
Should you use QuillBot?
QuillBot is a good choice for most people who need to reword text. In our test it kept the meaning of 16 of 20 passages, made only 1.1 errors per 1,000 words, and earned 4.0 out of 5 for readability from blind judges. That's why it scored 4 out of 5 and came 2nd of 6.
Start with the free plan. If you outgrow its 125-word limit or want the plagiarism checker, Premium is good value at $4.17 a month, billed yearly. Just keep reading what it gives you, since a few rewrites changed the meaning, and note the short 3-day refund window.
QuillBot suits students and writers who want an affordable all-in-one rewriter; anyone needing free long rewrites should look elsewhere.

If there's a strange new AI tool making its way around the internet, I've probably already bookmarked it. My favorite part is figuring out what these platforms can actually do.
