10 Best AI Paraphrasing Tools of 2026

This list is for students and writers choosing a paraphrasing tool by two numbers: how much the free version lets you rewrite and what the cheapest upgrade costs. We compared documented features and published prices for 10 tools and ranked them by value first, then features, then ease of use. Free limits are stated the way each vendor states them, in words, characters or rewrites per day, so read the unit before comparing. Prices are in USD as shown on each vendor's page on the check date; where a page showed only euros from our location, the price is marked pending.

   Best forStudents who paraphrase sources every week

   QuillBot ranks first because it has the deepest paraphraser on this list and a usable free tier. The free plan rewrites up to 125 words at a time in the Standard and Fluency modes, fixes basic grammar errors and creates summaries of up to 1,200 words. Premium removes the paraphrasing cap, opens 9 built-in modes such as Academic and Simple, and lets you create your own custom modes. It also adds a plagiarism checker that covers 25,000 words per month and summaries of up to 6,000 words. The paraphraser works in 23 languages, and apps cover Chrome, Edge, Safari, Word, macOS, Windows, iOS and Android. QuillBot says it is trusted by over 35 million writers. The weak spot for us is the price: the premium page showed only euros from our location, so the USD figure is pending. We compared documented features and published prices; we did not run test documents.

   • ✓The free plan covers short passages in two modes without payment
   • ✓Premium removes the paraphrasing word cap
   • ✓The vendor lists a 14-day money-back guarantee on Premium

   • ✕Free users get only 2 of the paraphrasing modes
   • ✕Plagiarism checks are Premium only
   • ✕The premium page showed only euro prices from our location

   Free word limit:

   125 words per paraphrase

   Free modes:

   Standard and Fluency

   Premium modes:

   9 built-in plus custom

   Languages:

   23 for paraphrasing

   Bottom line: QuillBot is the best paraphrasing tool for students because Premium offers 9 built-in modes, custom modes and a 25,000 word monthly plagiarism check. Its free plan is enough for passages of up to 125 words.

   Best forWriters who rephrase one sentence at a time

   Wordtune is second because it is cheap to upgrade and its limits are easy to understand. The free Basic plan gives 10 rewrites and AI suggestions per day, 3 AI summaries per month, and unlimited spelling and grammar checks. Advanced costs $4.89 per month on annual billing and raises the cap to 30 rewrites per day and 15 summaries per month. The Unlimited plan costs $6.99 per month on annual billing and removes the rewrite cap, adding vocabulary, clarity and fluency suggestions plus premium support. Students and educators with a valid .edu email can ask support for a 30% discount on annual and monthly plans. Both paid plans start with a 3-day free trial, though the FAQ says there are no refunds after that. Wordtune works through Chrome and Edge extensions and an iOS app. Its daily cap counts rewrites, not words, so it suits sentence work more than whole essays. We compared documented features and published prices.

   • ✓Advanced costs $4.89 a month on annual billing, one of the lowest paid prices here
   • ✓Both paid plans have a 3-day free trial
   • ✓Students with a .edu email can ask for 30% off

   • ✕The free plan stops at 10 rewrites per day
   • ✕Free users get only 3 AI summaries per month
   • ✕The FAQ says Wordtune does not offer refunds

   Free rewrites:

   10 per day

   Advanced rewrites:

   30 per day

   Unlimited plan:

   $6.99 per month billed annually

   Free trial:

   3 days

   Bottom line: Wordtune is the best low-cost upgrade for writers who rephrase sentence by sentence because Advanced costs $4.89 a month billed annually. Heavy users should go straight to the $6.99 Unlimited plan.

   Best forWriters who already use Grammarly for grammar

   Grammarly is third because its paraphraser comes free with an account and sits inside a tool many students already use for grammar. The paraphrasing page offers six preset styles and lets you add tone and style directions to create a custom voice that later rewrites follow. The free plan also checks spelling, grammar and tone and includes 100 AI prompts. Pro adds one-click full sentence rewrites in your documents, tone adjustment, fluency help, plagiarism checks and AI text detection, and raises the prompt allowance to 2,000. Grammarly reports more than 40 million people and 50,000 organizations using it. The page does not publish a word limit for the free paraphraser, so we did not score one. Value is lower than the two tools above because the Pro price was shown only in euros from our location; the USD check is pending. We compared documented features and published prices.

   • ✓The paraphraser is free with a Grammarly account
   • ✓Rewrites sit next to spelling, grammar and tone checks
   • ✓Grammarly says over 40 million people and 50,000 organizations use it

   • ✕One-click full sentence rewrites in your documents are Pro only
   • ✕Plagiarism checks are Pro only

   Bottom line: Grammarly is the best choice for writers who want paraphrasing and grammar checks in one free account because its paraphraser offers six preset styles at no cost. Pick QuillBot instead if you need plagiarism checks on a budget.

   Best forStudents who need longer free paraphrases

   Paraphraser.io earns fourth place on value. Its free tool accepts up to 400 words, more than three times the 125 word caps at QuillBot and Scribbr, and offers modes such as Fluency, Formal, Academic, Creative, Shorten and Expand. Paid plans are sold as word packs rather than unlimited subscriptions. Silver costs $4.55 for 7 days and 10,000 words, Gold costs $9.55 for 30 days and 30,000 words, and Diamond costs $47.52 billed annually for 250,000 words over 365 days. All three remove ads and reCAPTCHA, and Gold and Diamond add a dedicated manager. The pricing table lists 5 modes for paid plans, while the tool page shows more mode names, so check the mode you need before buying. The site also has a plagiarism checker, summarizer and AI humanizer. We compared documented features and published prices.

   • ✓The 400 word free box is the largest word limit among the word-capped free tools here
   • ✓Short weekly plan suits a single deadline
   • ✓Paid plans remove ads and reCAPTCHA

   • ✕Paid plans are word packs, so heavy users can run out

   Bottom line: Paraphraser.io is the best pick for students who need longer free paraphrases because its free box takes up to 400 words. Its $4.55 weekly pack suits one deadline.

   Best forBudget buyers who want unlimited rephrasing

   Ginger is the cheapest way on this list to get unlimited rephrasing. Its free Sentence Rephraser takes one sentence of up to 150 characters, then asks you to sign up and later to upgrade once the free limit is reached. Premium adds unlimited enhanced rephrasing with several suggestions per click, synonyms and tone variations, full-sentence grammar corrections and translation into 40+ languages. During the current 50% promotion, annual Premium is billed as one payment of $45, or $3.75 a month, and monthly billing costs $6.50. Students and teachers can get 70% off after an eligibility check, and there is a 7-day money-back guarantee. The Microsoft Office add-in is Windows only, and the Google Docs integration covers other users. Ginger rephrases sentences rather than whole documents, so it ranks below tools with bigger input boxes. We compared documented features and published prices.

   • ✓Annual Premium costs $3.75 a month during the promotion, the lowest paid price here
   • ✓Students and teachers can get 70% off after an eligibility check
   • ✓The upgrade page lists a 7-day money-back guarantee

   • ✕The free rephraser works on one sentence of up to 150 characters
   • ✕The Microsoft Office integration is Windows only
   • ✕Current prices depend on a 50% promotion

   Free rephraser:

   150 characters, limited uses

   Annual Premium:

   $45 per year ($3.75 a month)

   Monthly Premium:

   $6.50 per month

   Student discount:

   70% off with eligibility check

   Bottom line: Ginger is the best budget paraphraser because annual Premium costs $3.75 a month and includes unlimited rephrasing. It is weaker for whole paragraphs because it works one sentence at a time.

   Best forStudents who want a free paraphraser with no sign-up

   Scribbr's Paraphrasing Tool is the simplest free option for students. It is powered by QuillBot, runs without ads and needs no sign-up, and Scribbr says it is 100% free to use as often as you like. Each input can be up to 125 words, and you can upload a Word file, a Google Doc or a PDF instead of pasting. There are two modes: Standard, which balances change and meaning, and Fluency, which improves language and fixes grammar. Clicking any word opens a thesaurus so you can choose a different synonym. There is no premium paraphraser to buy, so you cannot lift the 125 word cap here. Scribbr sells a plagiarism checker and human proofreading separately, which helps students who want to check a paraphrased essay before submitting it. We compared documented features and published prices.

   • ✓No account, no ads and no fee
   • ✓Unlimited uses at 125 words per input
   • ✓Document upload saves copy and paste

   • ✕Only two modes
   • ✕The 125 word cap per input matches QuillBot's free plan
   • ✕Plagiarism checks are a separate paid Scribbr service

   Price:

   Sign-up:

   Not required

   Bottom line: Scribbr is the best no-sign-up paraphraser for students because it is free, ad-free and takes 125 words per input. Writers who need more modes should pick QuillBot.

   Best forMarketers who want tone control for free

   Ahrefs offers its paraphraser as one of a set of free writing tools, and it is useful when you want to steer tone. The page accepts up to 2,048 characters, lets you pick a language and a writing tone such as Formal, edit the sentence structure, and choose how many variants to generate. The page describes uses in academic writing, content creation and language learning. There is no paid plan for the paraphraser itself; Ahrefs' paid plans are SEO software and are not needed here. The 2,048 character box holds a few hundred words, less than Paraphraser.io's 400 word free limit, and there is no document upload, history or plagiarism check. It ranks below the student-focused tools because it does one job, but that job is free. We compared documented features and published prices.

   • ✓Free with no paid tier to upsell for paraphrasing
   • ✓Tone and variant controls go beyond a basic rewrite
   • ✓Part of a set of free Ahrefs writing tools

   • ✕2,048 characters is a few hundred words at most
   • ✕No document upload or browser extension listed
   • ✕No plagiarism check alongside the tool

   Input limit:

   Bottom line: Ahrefs is the best free paraphraser for marketers who want tone control because it offers tone, structure and variant settings at no cost. It holds only 2,048 characters per run.

   Best forNovelists who want rephrasing inside a full editor

   ProWritingAid is a full editing suite with paraphrasing built in. The free plan includes 10 Rephrases per day and line editing reports that run twice a day on 500 words of text. Premium costs $10 per month billed yearly at $120, or $30 on monthly billing, and adds unlimited Rephrases, unlimited line editing report runs, advanced style suggestions and Chapter Critique. Premium Pro costs $12 per month billed yearly and adds community access. A lifetime Premium license costs $399 as a one-time payment. Students can get 25% off yearly plans through Student Beans. Much of the product is aimed at novelists, with Story Canvas, plot analysis and a virtual beta reader, so essay writers pay for tools they may not use. That is why its value score sits below cheaper paraphrasers. We compared documented features and published prices.

   • ✓10 free Rephrases per day is the same daily allowance as Wordtune's free plan
   • ✓Students get 25% off yearly plans with Student Beans
   • ✓A lifetime license is available

   • ✕Monthly billing costs $30, three times the yearly rate
   • ✕Many features target fiction rather than essays
   • ✕Free line editing reports are capped at 500 words

   Free Rephrases:

   10 per day

   Premium:

   $10 per month billed yearly

   Monthly billing:

   $30 per month

   Lifetime:

   $399 one-time

   Bottom line: ProWritingAid is the best choice for novelists who want rephrasing inside a full editor because Premium adds unlimited Rephrases for $10 a month billed yearly. Students who only paraphrase should look at cheaper tools.

   Best forBloggers rewriting long text for free

   Spinbot has the biggest free input on this list: up to 10,000 characters, which the site puts at about 1,000 words per run. It offers a Basic Spin mode and an Advanced Paraphrase mode, can leave capitalized words such as names and titles unchanged, and has an ignore field for terms you want kept. A Chrome extension and a grammar checker are also offered. There is no paid plan listed. The trade-off is purpose: Spinbot describes itself as an article spinner for keeping website content fresh, and its page is written for SEO content rather than for students working with sources. Spun text usually needs careful editing before it reads well or is safe to submit, so we score features low. Use it for long drafts you will edit yourself, not for citations. We compared documented features and published prices.

   • ✓The 10,000 character free limit is the largest on this list
   • ✓No paid plan to buy
   • ✓Ignore list protects names and terms

   • ✕Built as an article spinner for SEO content rather than academic paraphrasing
   • ✕Few writing aids beyond rewriting and a grammar checker
   • ✕The page is ad-heavy marketing copy with no published model details

   Input limit:

   10,000 characters (about 1,000 words)

   Modes:

   Extension:

   Bottom line: Spinbot is the best free option for long rewrites because it takes up to 10,000 characters per run. Students should prefer QuillBot or Scribbr for academic text.

    Best forContent teams rewriting articles in bulk

    WordAi is a rewriting tool for content teams rather than students. It rewrites at the sentence and phrase level, supports bulk article uploads, HTML content, bulk downloads and spintax export, and includes API access on the standard plans. It also integrates with Article Forge for generating new articles. There is no permanent free plan. A 3-day free trial is followed by $27 per month billed annually or $57 on monthly billing, and an Enterprise plan adds multiple user accounts and higher throughput. WordAi also offers a 30-day money-back guarantee if you rewrite fewer than 10 articles. Much of the marketing focuses on passing AI detection, which is a poor fit for academic use, where schools judge work on honesty, not detector scores. It ranks last on value because it has the highest starting price and no free tier. We compared documented features and published prices.

    • ✓Bulk upload and API suit high-volume work
    • ✓3-day free trial plus a 30-day money-back guarantee
    • ✓Enterprise plan adds multiple user accounts

    • ✕No permanent free plan

    Bottom line: WordAi is the best choice for content teams that rewrite articles in bulk because it includes bulk rewriting and API access. Its $27 monthly starting price and lack of a free plan rule it out for most students.
