Last updated: February 2026
Quick Verdict: WordTune is one of the best AI-powered rewriting and paraphrasing tools available in 2026, excelling at sentence-level rewrites and tone adjustments. With over 10 million users, a 4.7/5 Chrome extension rating, and plans starting at $6.99/month, it’s a strong choice for non-native English speakers, students, and professionals who want to polish their writing without losing their voice. However, it falls short of all-in-one writing suites like Grammarly when it comes to deep grammar analysis and platform integrations.

What Is WordTune?
WordTune is an AI-powered writing companion developed by AI21 Labs, an Israeli artificial intelligence company founded in 2017. Unlike traditional grammar checkers that focus primarily on correcting errors, WordTune positions itself as a rewriting and paraphrasing assistant that helps you express your ideas more clearly, concisely, and compellingly.
At its core, WordTune analyzes the meaning behind your sentences — not just the structure — and offers multiple alternative ways to phrase the same thought. Think of it as having a writing partner who reads your draft and says, “Here’s what I think you’re trying to say,” then offers you five or six polished alternatives to choose from.
Since its launch, WordTune has grown to over 10 million users worldwide and has served up more than 782 million rewrite suggestions. It’s available as a Chrome browser extension, a web-based editor, a mobile app (iOS and Android), and integrates with popular platforms you already use daily.
What sets WordTune apart from competitors is its focus on preserving your authentic voice while improving your writing. Instead of auto-correcting everything into a single “correct” style, it offers contextual suggestions that match your existing tone and subject matter — giving you creative options rather than rigid corrections.
Key Features (In-Depth)
1. Smart Rewrites & AI Suggestions
This is WordTune’s flagship feature and the reason most people sign up. Highlight any sentence in your text, and WordTune instantly generates multiple rewritten versions that convey the same meaning with different phrasing.
What makes this genuinely useful:
- Multiple options per sentence — you’re not stuck with one suggestion, you get a variety to choose from
- Context-aware — the rewrites understand what you’re writing about and maintain coherence with surrounding text
- Style matching — suggestions try to match your existing writing voice rather than imposing a generic “AI tone”
For example, if you write “The project was really hard and took a long time,” WordTune might offer alternatives like “The project proved to be a significant challenge, requiring an extended timeline” or “Completing the project was demanding and time-intensive.” You pick the one that fits your situation.
On the free plan, you get 10 rewrites per day. The Plus plan bumps that to 30, and the Unlimited plan offers — as the name suggests — unlimited rewrites.
2. Tone Adjustment (Casual ↔ Formal)
One of WordTune’s most practical features is the ability to shift your writing between casual and formal tones with a single click. This is incredibly handy when you’re:
- Drafting a work email that started too casual
- Adapting academic writing into a blog post or social media caption
- Adjusting customer communications to match the expected formality level
The tone adjustment isn’t just about swapping “can’t” for “cannot” — it restructures sentence patterns, adjusts vocabulary complexity, and changes the overall register in a way that feels natural.
3. AI Summarization
WordTune’s summarizer goes beyond basic text — it can condense documents, articles, webpages, and even YouTube videos into concise summaries. This is a feature that many competitors don’t offer at all, and it’s particularly valuable for:
- Students doing research who need to quickly assess whether a source is relevant
- Professionals who need to digest long reports or industry articles
- Content creators looking for inspiration or key points from existing material
The free plan limits you to 3 AI summarizations per month, the Plus plan gives you 15 per month, and the Unlimited plan offers unlimited summarizations.
According to WordTune’s own data, users report a 25% reduction in research time thanks to the summarization feature — and from our testing, that number feels realistic.
4. Continue Writing (AI Text Generation)
When writer’s block hits, WordTune’s “Continue Writing” feature picks up where you left off. Unlike standalone AI generators (like ChatGPT), this feature is designed to generate text that blends seamlessly with what you’ve already written — matching your style, tone, and subject matter.
Additional AI generation options include:
- Elaborate on your answer — expand on a point you’ve made
- Propose an alternate viewpoint — offer a counterargument or different perspective
- Explain in further detail — break down complex points
- Add emphasis — strengthen a particular argument
- Add a conclusion — wrap up a paragraph or section
This is where WordTune starts to blur the line between “writing assistant” and “AI co-writer,” and it does it well. The generated text feels more natural and connected to your existing work than what you’d get from a generic AI prompt.
5. Grammar & Spelling Correction
Yes, WordTune also handles the basics. Its grammar and spelling correction engine flags errors and offers fixes in real-time as you type. This includes:
- Spelling mistakes
- Subject-verb agreement
- Punctuation errors
- Common grammatical errors
It’s worth noting that grammar correction is available on all plans, including the free tier, with unlimited usage. However, WordTune’s grammar checking isn’t as deep or comprehensive as dedicated tools like Grammarly or ProWritingAid. It catches the common stuff reliably, but power users who need detailed explanations of grammar rules or advanced style checks should consider pairing it with another tool.
6. Smart Translate (10 Languages)
WordTune supports translation from 10 languages into English: Spanish, Mandarin, Arabic, Hindi, Korean, Hebrew, Russian, German, French, and Portuguese. This isn’t a standard translation feature — it’s what WordTune calls “Smart Translate,” designed to make translated text sound like it was written by a native English speaker.
For non-native English speakers, this is arguably WordTune’s most transformative feature. Instead of translating literally (which often sounds awkward), it adapts idioms, restructures sentences for English conventions, and polishes the output so it reads naturally.
7. Vocabulary Enhancement (Smart Synonyms)
WordTune’s Smart Synonym feature suggests contextually appropriate word alternatives as you write. This goes beyond a basic thesaurus — suggestions are weighted by context, ensuring you don’t accidentally swap in a word that technically means the same thing but carries a different connotation.
This feature is particularly useful for:
- Avoiding repetitive language in long-form content
- Elevating word choice for academic or professional writing
- Learning new vocabulary organically as you write
8. Fact-Checking with Citations
In the age of AI-generated misinformation, WordTune takes a notable stance on accuracy. The platform claims to check at least 5 sources before deeming a fact credible for use in AI-generated content. When WordTune generates text that includes factual claims, it provides citations and sources alongside the output.
This is particularly valuable for:
- Academic writing where citations are mandatory
- Professional reports where accuracy matters
- Content creation where credibility is essential
It’s not a replacement for proper research, but it’s a meaningful step toward responsible AI writing that many competitors haven’t taken.
9. Cross-Platform Availability
WordTune works across:
- Chrome browser extension (4.7/5 rating on the Chrome Web Store)
- Web-based editor at app.wordtune.com
- iOS app (97% App Store rating)
- Android app
- Integration with popular apps and platforms
The Chrome extension is the most popular way to use WordTune, as it overlays on virtually any text field — Gmail, Google Docs, LinkedIn, social media platforms, and more. The mobile apps are a nice addition for writing on the go, though the experience is naturally more limited on smaller screens.

The Unlimited plan at $6.99/month (annual billing) is competitively priced compared to Grammarly Premium ($12/month annual) and ProWritingAid ($10/month annual), making it an attractive option if rewriting and paraphrasing are your primary needs.
Pros and Cons
✅ Pros
❌ Cons
Who Is WordTune Best For?
🎯 Perfect For:
Non-native English speakers — This is WordTune’s sweet spot. The combination of Smart Translate, fluency improvements, and natural-sounding rewrites makes it the best AI writing tool for ESL writers who want their English to sound polished and native.
Students and academics — The paraphrasing tools help avoid plagiarism when referencing sources, the summarization feature speeds up research, and the tone adjustment feature helps shift between casual notes and formal papers. Plus, the 30% student discount sweetens the deal.
Email-heavy professionals — If your job involves writing dozens of emails daily, WordTune’s tone adjustment and rewriting features help you craft messages faster without sounding robotic. Customer-facing teams particularly benefit.
Content creators and copywriters — The rewriting engine is gold for generating alternative headlines, rephrasing social media captions, and polishing blog drafts. The “Continue Writing” feature helps push through creative blocks.
Customer support teams — Multiple user testimonials report 30% improvement in CSAT scores and significant time savings when using WordTune for customer communications.
🚫 Not Ideal For:
Writers who need deep grammar analysis — If you want detailed grammar explanations, writing style reports, and readability metrics, Grammarly or ProWritingAid are better choices.
Multi-language writers — WordTune only outputs in English. If you write in multiple languages, you’ll need a tool like DeepL Write or LanguageTool.
Users who need plagiarism checking — You’ll need to pair WordTune with a separate plagiarism tool, which adds cost and friction.
Enterprise teams — While a Business plan exists, WordTune’s enterprise features (SSO, centralized billing) are still maturing compared to Grammarly Business, which has years of head start in the enterprise market.
WordTune vs. Competitors
Here’s how WordTune stacks up against the most popular writing assistants in 2026:
WordTune vs. Grammarly
Grammarly is the 800-pound gorilla of writing assistants, and for good reason — it offers the most comprehensive grammar checking, style analysis, and platform integrations available. Grammarly Premium ($12/month annual) provides detailed writing reports, tone detection, plagiarism checking, and plugins for virtually every platform.
Choose WordTune if: You primarily need better sentence phrasing, are a non-native speaker, or want strong paraphrasing at a lower price.
Choose Grammarly if: You need thorough grammar analysis, plagiarism detection, team features, or the widest possible platform compatibility.
WordTune vs. QuillBot
QuillBot is WordTune’s most direct competitor, as both focus heavily on paraphrasing and rewriting. QuillBot offers multiple paraphrasing modes (Standard, Fluency, Formal, Simple, Creative, Expand, Shorten) and includes a built-in plagiarism checker. QuillBot Premium starts at around $9.95/month (annual).
Choose WordTune if: You value more natural-sounding rewrites, need summarization features, or want AI text generation capabilities.
Choose QuillBot if: You need a plagiarism checker included, prefer more control over paraphrasing modes, or want a slightly more affordable option with comparable features.
WordTune vs. ProWritingAid
ProWritingAid is the deep-dive grammar and style tool favored by fiction writers and serious editors. It provides 20+ writing reports covering readability, pacing, dialogue, clichés, and more. ProWritingAid Premium costs around $10/month (annual).
Choose WordTune if: You need quick rewriting and paraphrasing assistance, are an ESL writer, or prefer a simpler interface focused on rewrites.
Choose ProWritingAid if: You’re a fiction writer, want in-depth style analysis, or need comprehensive writing reports that teach you to improve.
WordTune vs. Hemingway Editor
Hemingway Editor takes a completely different approach — it highlights overly complex sentences, passive voice, and readability issues using color-coded feedback. It’s simple, focused, and available as a one-time desktop purchase ($19.99) or free web app.
Choose WordTune if: You need active rewriting suggestions, AI text generation, or multi-language translation support.
Choose Hemingway if: You want a minimalist readability checker, prefer a one-time purchase over subscriptions, or want to learn to write more concisely through visual feedback.

Frequently Asked Questions
Is WordTune safe to use?
Yes. WordTune is developed by AI21 Labs, a reputable AI research company. The tool processes your text through its servers to generate suggestions, which is standard for AI writing tools. They have a privacy policy in place, and your text is used to generate suggestions — not publicly shared. That said, avoid pasting highly sensitive or confidential information into any cloud-based writing tool. For enterprise-level security needs, the Business plan offers SAML SSO and centralized administrative controls.
Is WordTune worth it in 2026?
For its core strengths — sentence rewriting, paraphrasing, and tone adjustment — absolutely yes. If these are the features you need most, WordTune offers the best experience at a competitive price ($6.99/month on the annual plan). However, if you need a comprehensive grammar suite with plagiarism checking and enterprise integrations, Grammarly or ProWritingAid may offer more overall value. WordTune is worth it if you know what you’re buying.
Can WordTune be detected as AI writing?
WordTune’s rewrite suggestions are specifically designed to preserve your original voice and meaning while improving phrasing. Since you’re selecting from suggestions rather than generating entirely new text, the output typically reads as human-written. However, if you use the “Continue Writing” feature extensively to generate new paragraphs, AI detection tools may flag that content. The rewriting features — which polish your existing words — are generally undetectable because they build on genuinely human-written text.
Does WordTune offer a student discount?
Yes. Students and educators with a valid .edu email address can receive a 30% discount on both annual and monthly plans. This applies to anyone currently enrolled at or working at an academic institution, as well as non-profit employees. To apply, you’ll need to contact WordTune’s support team directly through their Help Center or at help@wordtune.com.
Can I use WordTune on my phone?
Yes. WordTune offers native mobile apps for both iOS and Android. The mobile experience includes most core features — rewriting, grammar checking, and summarization. The mobile apps have strong ratings (97% positive on the App Store). However, the desktop Chrome extension and web editor provide the fullest experience, as they can overlay on any website and offer a larger editing workspace.
Does WordTune work with Microsoft Word?
As of early 2026, WordTune does not offer a dedicated Microsoft Word plugin. Its primary integration is through the Chrome browser extension, which works on Google Docs, Gmail, and most web-based applications. If you primarily work in Microsoft Word or Outlook desktop applications, this is a notable limitation compared to Grammarly and ProWritingAid, which both offer native Word plugins.
How does WordTune compare to using ChatGPT for rewriting?
While ChatGPT and other general-purpose AI chatbots can rewrite text when prompted, WordTune offers a more streamlined and purpose-built experience. With WordTune, you highlight a sentence and instantly get multiple rewrite options without crafting prompts. The suggestions are integrated into your workflow (via browser extension or editor), maintain your voice more consistently, and are optimized specifically for rewriting rather than general text generation. ChatGPT is more versatile overall, but WordTune is faster and more refined for the specific task of polishing and paraphrasing text.
Final Verdict
WordTune earns a solid 4.2/5 in 2026. It’s not trying to be everything to everyone, and that’s actually its strength.
If you need the best sentence-level rewriting tool on the market, WordTune delivers. Its core rewriting engine is genuinely best-in-class — the suggestions feel natural, diverse, and authentically matched to your voice. For non-native English speakers, it’s an even stronger recommendation thanks to Smart Translate and fluency improvements that make English writing feel effortless.
The Unlimited plan at $6.99/month (billed annually) is competitively priced and represents solid value, especially with the 3-day free trial to test everything before committing. The free plan is genuinely functional for light use, and the student discount makes it accessible for budget-conscious academics.
Where WordTune falls short is in trying to be a complete writing suite. Its grammar checking is adequate but not exceptional, it lacks plagiarism detection, and its platform integrations are narrower than Grammarly’s. If you need all-in-one coverage, you’ll either need to pair WordTune with another tool or choose a more comprehensive alternative.
The bottom line: WordTune does a few things exceptionally well rather than doing everything adequately. If rewriting, paraphrasing, and tone adjustment are your primary needs — and especially if English isn’t your first language — WordTune is one of the best investments you can make in your writing.
If deep grammar analysis, plagiarism detection, and maximum platform coverage matter more to you, look at Grammarly Premium or ProWritingAid instead.
Try WordTune free to see if its rewriting suggestions click with your workflow. You might be surprised how much a well-phrased sentence can change.
