Wordtune
Wordtune is an AI writing assistant from AI21 Labs that paraphrases, rewrites, proofreads, and summarizes text and YouTube videos.
If rewriting and summarizing are the job, Wordtune does them for a price Grammarly can't match: Unlimited at $6.99/mo billed annually covers unlimited rewrites, AI suggestions, and AI summarizations, and $9.99/mo if you pay month to month. Its summarizing extends to YouTube videos and webpages, which most writing assistants skip. The ceiling is real, though: it writes in English only, has no plagiarism checker, and its style rules are not as deep as Grammarly's. Pick Wordtune when paraphrasing, tone-shifting, and condensing long reads are the daily work; keep Grammarly in the stack if you need forensic style enforcement.

About Wordtune
Wordtune is a paraphrasing and reading assistant made by AI21 Labs. Highlight a sentence and it returns a list of context-based rewrite options; you can flip any sentence between formal and casual tone with a click, or stretch/shorten it to fit a word count. Spelling, grammar, and phrasing get cleaned up as you type. The reading side condenses documents, articles, webpages, and YouTube videos so you can triage long material before committing to a full read. Beyond rewriting it generates original copy in your style, continues a stalled draft, proposes an alternate viewpoint, adds a conclusion, and offers a smart synonym finder. Smart Translate turns Spanish, Mandarin, Arabic, Hindi, Korean, Hebrew, Russian, German, French, or Portuguese into English; a Humanize AI mode reworks AI-generated text; and a fact-check layer says it verifies claims against at least five sources. It runs as a Chrome or Microsoft Edge extension and an iOS app, working inside Gmail, Google Docs, Outlook, LinkedIn, and WordPress instead of a separate editor. AI21 Labs reports 10M+ users, a 4.7/5 Chrome extension rating, a 97% App Store rating, and 782M rewrite suggestions chosen. Free Basic covers 10 rewrites/AI suggestions per day and 3 AI summarizations per month; Advanced is $4.89/mo billed annually ($6.99/mo monthly) at 30 rewrites/day and 15 summaries/month; Unlimited is $6.99/mo billed annually ($9.99/mo monthly) with unlimited rewrites and summaries plus vocabulary, clarity, and fluency enhancements. Wordtune writes in English only — it translates into English, it doesn't produce other languages — and it's a paraphrasing specialist rather than a Grammarly-depth style suite, with no plagiarism detection.
Behind the Verdict
Wordtune's strength is narrow and honest: it is very good at taking a sentence you're unhappy with and giving you several different ways to say it. The rewrite suggestions are context-aware and come with one-click formal/casual toggling plus lengthen/shorten controls — the mechanisms you actually use when drafting an email, tightening a paragraph, or hitting a word count. AI21 Labs says 782M rewrite suggestions have been chosen, which is consistent with a tool people reach for sentence by sentence rather than as a full editor. The reading side is the underrated half. You can paste a document, article, or YouTube link and get a summary, which changes how you triage research: skim summaries, then read the two items worth reading in full. Its fact-check layer claims to check at least five sources before calling a fact credible — treat it as a starting signal, not an audit trail. Where it fits: non-native English speakers who can translate from Spanish, Mandarin, Arabic, Hindi, Korean, Hebrew, Russian, German, French, or Portuguese into English and then rewrite for native-sounding phrasing; students paraphrasing sources and summarizing papers; professionals shifting tone between formal and casual across Gmail, Google Docs, Outlook, LinkedIn, and WordPress; and content teams humanizing AI-generated copy. Free Basic is genuinely usable at 10 rewrites and 3 summaries a day/month; Advanced at $4.89/mo billed annually ($6.99/mo monthly) is the tier for someone who hits that wall daily; Unlimited at $6.99/mo billed annually ($9.99/mo monthly) removes the caps and adds vocabulary, clarity, and fluency enhancements. Where it doesn't: Wordtune writes in English only, so anyone needing output in Spanish, German, or Mandarin is in the wrong tool — the translation feature runs into English, not out of it. There is no plagiarism checker, so academic integrity workflows need another product. And its grammar and style checks are not as deep as a dedicated grammar suite, so teams enforcing a strict style guide should treat Wordtune as the rewriting layer and something else as the rule engine. Teams that need one shared collaborative document with tracked co-authoring should also look elsewhere; Wordtune is an assistant that sits inside your existing apps rather than a shared writing workspace.

Real-world workflow fit
Concrete scenarios for the personas Wordtune actually fits — and what changes day-one when you adopt it.
Write the email in your head, run sentences through Wordtune's Smart Translate from German or Portuguese into English, then use context-based rewrites and the formal/casual toggle to match the client's register inside Gmail.
Outcome: An email that reads as native English without a separate editing pass, produced in the same Gmail window via the Chrome or Edge extension.
Paste journal article links and YouTube lecture links into Wordtune's summarizer to get 3 summaries on the Basic tier or 15 per month on Advanced, then rewrite the key paragraphs you quote into your own phrasing.
Outcome: You decide which two of ten sources deserve a full read, and paraphrased passages come back in your own voice rather than the source's.
Draft in Google Docs with the Wordtune extension open, use Continue Writing when a section stalls, add a conclusion at the end, run AI-assisted copy through Humanize AI, and generate multiple social caption options for the same post.
Outcome: First-draft-to-publishable copy stays inside Google Docs and WordPress, with the Unlimited tier removing the rewrite and summarization caps so output volume isn't throttled.

For each published Wordtune tier: who it actually fits, and what it adds vs. the previous tier. Cross-reference the cost calculator above for projected annual outlay.
Basic
$0/mo
Ideal for
Casual writers who mostly want free spelling and grammar cleanup and only occasional rewrites — students between assignments or someone testing the tool before paying.
What this tier adds
Free entry point: unlimited spelling and grammar checks, but capped at 10 rewrites and AI suggestions per day and 3 AI summarizations per month, with limited AI generations.
Advanced
$4.89/mo billed annually ($6.99/mo monthly)
Ideal for
Individuals who rewrite something every working day — a non-native speaker polishing daily emails, or a student paraphrasing sources weekly — but don't need unlimited summaries.
What this tier adds
Triples the daily rewrite allowance to 30 and raises AI summarizations to 15 per month, and adds unlimited AI recommendations over Basic. $4.89/mo billed annually, $6.99/mo monthly.
Unlimited
$6.99/mo billed annually ($9.99/mo monthly)
Ideal for
Content marketers, bloggers, and professionals whose daily output regularly exceeds 30 rewrites — anyone who wants the caps gone for under $7/mo billed annually.
What this tier adds
Removes all rewrite, AI suggestion, and AI summarization caps and adds vocabulary enhancements, clarity improvements, fluency increases, and premium support. $6.99/mo billed annually, $9.99/mo monthly.
Business
Custom
Ideal for
Organizations that need company-wide deployment with single sign-on and one consolidated invoice rather than individual subscriptions.
What this tier adds
Adds SAML SSO, centralized billing, and business support on top of the writing features. Priced as Custom, so procurement talks to the vendor rather than a self-serve checkout.

Setup time & first value
How long it actually takes to get something useful out of Wordtune — broken out by persona, not the marketing-page minute.
For an individual writer, first value comes in a few minutes: install the Chrome or Microsoft Edge extension or the iOS app, sign in, and start rewriting in Gmail, Google Docs, or Outlook. Teams evaluating it should budget for a 3-day free trial on Advanced or Unlimited, which requires payment information up front. Business-tier buyers adding SAML SSO and centralized billing should expect an
Switching to or from Wordtune
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Grammarly: keep Grammarly for deep style rules and add Wordtune as the rewriting and summarizing layer, since Wordtune covers paraphrase, tone switching, and AI summaries rather than full style enforcement.
- →From a manual editing pass: install the Chrome or Edge extension and work inside Gmail, Google Docs, Outlook, LinkedIn, or WordPress instead of a separate editor.
- →From drafting in a second language: use Smart Translate from Spanish, Mandarin, Arabic, Hindi, Korean, Hebrew, Russian, German, French, or Portuguese into English, then rewrite for natural phrasing.
- →From copy-pasting into a chatbot: use Continue Writing and context-based suggestions that match your existing style instead of re-prompting from scratch.
- ↗To Grammarly: move if you need deep style-rule enforcement and plagiarism detection, accepting that you'll lose Wordtune's video and webpage summarization.
- ↗To a full AI writing suite: move if you need non-English output, since Wordtune only writes in English despite translating into it.
- ↗To a shared collaborative doc: move if your team needs real-time co-authoring in one document rather than an assistant inside each person's apps.
- ↗To a free tool: move to Wordtune's own Basic tier first — $0/mo with unlimited spelling and grammar checks covers light editing before you pay for anything.
