How we researched this
We compared official pricing and feature pages, app store listings, privacy policies and public user reviews. Prices change, so check the provider's site before you pay.
Key takeaways
- QuillBot is our pick for mode-based paraphrasing, with nine rewrite modes and a usable free tier.
- Wordtune suits sentence-level rewrites, while Grammarly suits polishing grammar, clarity, and tone in one place.
- Free tiers help for occasional use, but word caps per pass mean long documents need chunking or a paid plan.
- Paraphrasing does not remove the need to cite sources, and school or work AI policies still apply.
- The cheapest tool is not always the best fit, since grammar, summarising, and plagiarism checks are separate jobs.

The best AI paraphrasing tools
Paraphrasing tools rewrite text while keeping its meaning, which helps when a sentence is awkward, too formal, or too close to a source. The best tools do more than swap synonyms. They adjust tone, shorten or expand a passage, and keep grammar intact. We compared official pricing pages, free limits, and feature pages for each tool below.

QuillBot is the most paraphrase-focused tool in this list, and that focus shows. Modes such as Standard, Fluency, Formal, Simple, Creative, and Expand let you steer a rewrite toward a clear goal, rather than accepting one generic output. The summariser helps when you need a short version of a long passage, and the grammar checker catches errors the rewrite may introduce.
The free plan allows 125-word paraphrases in two modes, which is enough for single sentences and short paragraphs. Premium costs $8.33 per month billed annually, or $19.95 billed monthly, and lifts word limits and opens all modes. If paraphrasing is your main job, QuillBot is the natural starting point.
- Nine rewrite modes
- Summariser and grammar checker
- Plagiarism checker on paid plans
- Free paraphrases cap at 125 words per pass
- Best features sit behind Premium

Wordtune works best at sentence level. Highlight a sentence, and it offers alternatives that keep the meaning while changing structure or tone. That makes it useful for emails, essays, and work documents where one awkward sentence blocks the whole paragraph. Tone controls help shift writing from casual to formal without rewriting from scratch.
The free plan includes 10 rewrites a day and a small number of summaries a month, with unlimited spelling and grammar checks. Paid plans start at about $6.99 per month for Advanced and about $9.99 per month for Unlimited on annual billing. Wordtune suits writers who already have a draft and want better sentences, not a tool to generate text from nothing.
- Context-aware sentence alternatives
- Casual and formal tone options
- Summarising tools
- Free plan allows 10 rewrites a day
- No mode selector like QuillBot
- No plagiarism checker

Grammarly is an editor first and a paraphraser second, and that order matters. It checks grammar, spelling, clarity, and tone wherever you type, from email to documents, and its AI prompts help reword sentences. The free plan covers basic grammar checks and a set of AI prompts each month, which is enough for everyday writing.
Pro costs $12 per month billed annually, or $30 per month billed monthly. If your main problem is errors and unclear sentences, rather than a need for many rewrite styles, Grammarly covers more of your writing day than a paraphrase-only tool. Pair it with QuillBot free for occasional mode-based rewrites if you need both jobs done.
- Works across browser, desktop, and documents
- Strong grammar and tone checks
- Free basic checks
- Rewrites are more conservative than QuillBot
- Pro is $30 per month on monthly billing
Scribbr is well known to students for citation, proofreading, and plagiarism checking, and its free paraphraser fits that workflow. You can reword short passages without creating an account, using Standard and Fluency modes. That low friction helps for a quick sentence fix during an essay draft.
The paid side is different from a monthly writing app. Plagiarism checks are priced per document, and human proofreading is priced by word count, so costs depend on the job. Scribbr also states that its paraphraser is powered by QuillBot technology, so it is best seen as a student-friendly front door to a familiar engine, plus academic services around it.
- Free paraphraser with no signup for short passages
- AI detector free sample
- Student-focused services
- Free paraphrase cap is 125 words
- Paid services are priced per document, not monthly
Paraphraser.io appeals to budget users because its free tier allows longer passages than QuillBot, with a published free allowance around 500 words and two modes. That makes it practical for a full paragraph without splitting it into many small pieces. Paid plans add more words, modes, and features for heavier use.
Output quality depends on the mode and the source text, so read every rewrite closely, especially for technical or academic writing. The tool is a good backup when QuillBot free caps block you, but it is not a full writing suite. Use it for paraphrasing, and use a separate grammar checker for final polish.
- Larger free word allowance than QuillBot
- Several rewrite modes
- Simple web tool
- Interface and output quality vary by mode
- Pricing and limits change, so check before paying
Hemingway Editor does a different job from QuillBot, and it earns its place because many paraphrase problems are really clarity problems. It highlights long sentences, hard-to-read passages, adverbs, and passive voice, and it gives a readability grade. The free web editor covers basic highlighting, which helps you tighten a draft yourself.
Editor Plus, at about $8.33 per month billed annually, adds AI features and more editing tools. If your writing is wordy rather than wrong, Hemingway shows you where to cut. Use it after paraphrasing, or on its own when you want shorter, plainer sentences without changing meaning through AI rewrites.
- Highlights dense sentences and passive voice
- Free web editor
- Readability focus
- Not a true paraphraser
- Paid Editor Plus needed for AI rewrites and full features
Rytr is a budget AI writing tool that can rewrite, expand, shorten, and draft short text. Its free plan allows 10,000 characters a month, and Unlimited costs $7.50 per month billed annually, or $9 per month billed monthly. That price makes it attractive for students and freelancers who need occasional help across many small writing jobs.
The trade-off is focus. Rytr is not as strong a dedicated paraphraser as QuillBot or Wordtune, and its output can sound generic if you accept it without edits. Treat it as a low-cost helper for drafts, social posts, and emails, and keep a dedicated checker for work that must be precise.
- Very low paid price
- Many tones and use cases
- Free character allowance each month
- Paraphrasing is one feature among many
- Output needs careful editing for formal work
DeepL Write builds on DeepL translation strength to offer fluent rewrites and style suggestions. It suits non-native English writers who want natural phrasing, and multilingual teams who already trust DeepL for translation. Tone and style options help adapt a draft for formal or friendly contexts.
Availability and pricing for Write depend on plan and region, and the free translation plan does not include the full Write feature set, so check the DeepL pricing page for your country before budgeting. If English fluency is your main barrier, DeepL Write is worth testing alongside Grammarly, since its phrasing often sounds more natural.
- Strong fluency from DeepL language models
- Tone options
- Good for non-native writers
- Full Write features sit on paid plans
- Free translation plan is separate from Write
How we picked these
We compared official pricing pages, free-plan word and rewrite caps, rewrite modes, and related features such as grammar checking, summarising, and plagiarism detection. We kept only tools that are live in 2026 and that truly rewrite text, not general chatbots alone. We did not claim hands-on testing, and we did not invent accuracy scores, user counts, or awards.
Using paraphrasing tools honestly
Paraphrasing well means changing structure and wording while keeping meaning, and then citing the source where the idea came from. A tool can help you find clearer phrasing, but it does not make someone else's idea your own. Always check your school, publisher, or employer AI policy before using these tools on submitted or published work, since rules differ widely.
Read every rewrite before you use it. Tools can change meaning, drop a qualifier, or invent a smoother sentence that says something different from your source. That risk is highest with technical terms, numbers, and legal or medical wording. Keep the original beside the rewrite, check names and figures, and edit until the new version is both clear and faithful.

Frequently asked questions
What is the best AI paraphrasing tool overall?
QuillBot is the best dedicated paraphraser for most people, because of its nine modes and usable free tier. Wordtune is better for single-sentence rewrites, and Grammarly is better if grammar and clarity matter more than rewrite variety.
Is there a free AI paraphrasing tool?
Yes. QuillBot, Wordtune, Scribbr, and Paraphraser.io all have free tiers, but they cap words or rewrites. For occasional short passages, the free tiers are enough, while long documents usually need a paid plan or chunking.
Does paraphrasing avoid plagiarism?
No, not on its own. Changing words without citing the source can still be plagiarism, and many schools treat uncredited AI paraphrasing as academic misconduct. Cite sources, follow your institution policy, and rewrite in your own structure.
Can these tools paraphrase a whole essay at once?
Most free plans cannot, because they cap words per pass. Paid plans raise limits, but long documents still work best in sections, with a careful read after each rewrite to check that meaning has not drifted.
Is QuillBot better than Grammarly for paraphrasing?
For paraphrasing alone, yes, because QuillBot offers more modes and higher word limits on paid plans. Grammarly is stronger as an everyday editor for grammar, tone, and clarity across all your writing.
Which tool is best for students?
QuillBot and Scribbr are the most student-friendly, with free short paraphrases and academic services around them. Check your course AI policy first, and use the tools to improve your own draft, not to replace your own work.
