Wordtune review: pricing, features and what testers found

Wordtune is AI21 Labs' AI rewriting assistant for English: it suggests other ways to say a sentence or paragraph, changes tone and length, continues your text, corrects spelling and grammar and summarizes articles and PDFs, in a web editor, Chrome, Edge and Firefox extensions and an iPhone app. Basic is free with 10 rewrites a day; Advanced costs $13.99 a month ($6.99 billed yearly) and Unlimited $19.99 ($9.99 billed yearly).

Our take

Wordtune's tested strength is sentence-level rewriting rather than drafting: Zapier's Kiera Abbamonte (June 2025) chose it among six grammar checkers as the pick for rewriting, shortening and expanding text, and in October 2025 Cybernews' Inga Valiaugaitė ranked it second of seven paraphrasers, finding its Casual, Formal, Shorten and Expand rewrites read as if she had written them. The summarizer test cited here dates from March 2023, when it was the separate Wordtune Read app: Lifehacker's Jake Peterson found it handled a long article and a 36-page study but flattened narrative writing. Advanced costs $13.99 a month ($6.99 a month billed yearly) for 30 rewrites a day, and Unlimited $19.99 ($9.99 billed yearly). Weigh a yearly plan carefully: Calcalist reports AI21 Labs stopped developing Wordtune in April 2025, and Wordtune gives no refunds.

Based on Wordtune's published plans and the hands-on tests linked below, not on a test of our own.

Good for

  • Non-native English writers who want more natural phrasing in emails, messages and essays, including text first written in one of the 10 supported languages
  • Adjusting the tone and length of your own drafts sentence by sentence, in the browser where you already write
  • Skimming long articles and PDFs with summaries you can check against the passage each one came from

Watch out for

  • AI21 Labs stopped developing Wordtune in April 2025, Calcalist's Ctech reported, and in May 2026 Ctech reported that AI21 had announced it would lay off 110 of its 180 employees; Ctech calls its Maestro agent platform effectively the company's only remaining active product line. Wordtune is still sold and updated now and then (Chrome and Edge extension 9.20.0 on April 19, 2026, iPhone app 2.0.10 on May 18, 2026, terms revised August 31, 2026), but the Firefox add-on was last updated in April 2025.
  • No refunds: the terms and help center refuse refunds or credits for unused time, and cancelling from your account page only stops the next renewal. The 3-day free trial on both paid plans needs a card and bills when it ends unless you cancel first.
  • The low prices are yearly: $6.99 and $9.99 a month are billed annually ($83.88 and $119.88 a year) and the pricing page opens on that view; month to month, Advanced costs $13.99 and Unlimited $19.99. Buying in the iPhone app costs more: the US App Store lists Premium at $24.99 a month or $119.99 a year.
  • Your text: the terms give Wordtune a perpetual, irrevocable licence to copy, store and use what you enter to run and improve the service, including its algorithms, and the privacy policy lets AI21 aggregate your content to develop its products unless you email privacy@wordtune.com to opt out, although the FAQ says 'we cannot see your writing'. The terms forbid entering health, financial, password or ID data.
  • The consumer licence covers your own personal purposes, and the terms say summaries are for personal use only. Wordtune Business (teams of three or more, with a Traceless security mode) is being offered only to existing business accounts for now, the help center says, and wordtune.com/business/pricing redirects to the consumer plans.
  • No plagiarism or AI-detection checks: the footer's AI content detector page returns a 404, Zapier notes there is no plagiarism check, and the help center says it cannot guarantee rewrites will not be flagged by a plagiarism checker. The Chrome listing calls Wordtune 'AI Detection Resistant', but Cybernews found it has no AI-detection bypass.
  • Wordtune's own pages disagree: the pricing page lists AI generations on the free plan without saying how many, while the help center keeps Ask AI off it; the discount article says the 30% student, educator and non-profit discount cannot be combined with yearly billing, while the pricing page's FAQ offers it on annual and monthly plans; the Summarizer page says the extension summarizes, while the help center's comparison says it does not; and older pages still use the retired Premium, Plus and Spices names.
  • The Chrome Web Store rates the extension 3.3 from 2,390 ratings, though Wordtune's home page still claims 4.7/5, and three Trustpilot reviews posted between September 30 and October 15, 2026 say the iPhone app's Ask AI text generation (Ask Wordtune) had stopped working.

What hands-on testers found

We have not tested Wordtune ourselves. These are the published tests we found that used it hands-on, newest first; follow the links for the full reviews.

Cybernews · Inga Valiaugaitė · updated October 10, 2025

What they tested: Seven AI paraphrasing tools scored on rewrite quality, features, results against AI detectors (she names Turnitin and GPTZero), pricing and privacy; for Wordtune she used the Casual, Formal, Shorten, Expand and plain rewrite modes. The article gives no version or plan.

  • She found it the most flexible of the seven on tone: its rewrites went beyond swapping synonyms and read as if she had written them, which suited emails and essays where tone matters.
  • The free plan's 10 rewrites a day were limiting, though she judged the quality of the output made up for it.
  • It has no AI-detection bypass, and the best of its suggestions has to be picked by hand.

Their score: Ranked 2nd of 7 AI paraphrasing tools

Zapier · Kiera Abbamonte · updated June 3, 2025

What they tested: More than 30 grammar checkers narrowed to six, each signed up for and run through scenarios such as fixing spelling and grammar errors and cutting fluff; she describes Wordtune in Google Docs through the extension and in its online editor, on today's plan structure (10 free rewrites a day, paid plans from $6.99 a month billed yearly). The article, first written by David Hartshorne in May 2023, gives no version.

  • Chose Wordtune among the six as the pick for rewriting, shortening and expanding text, and called it a companion to Grammarly; it has no plagiarism check.
  • In Google Docs its icon waits on screen, and highlighting text brings back several alternatives, which helps when a draft needs a fresh take.
  • The online editor adds a spelling and grammar checker and a proofreader for clarity and fluency, but nothing to enforce a consistent style the way ProWritingAid or Grammarly can.

Lifehacker · Jake Peterson · March 2, 2023

What they tested: Wordtune Read, then a separate summarizing web app (the help center now places the Summarizer in the Wordtune Editor), on its free tier: a New York Times article labeled a 10-plus-minute read and an uploaded 36-page education study. The test predates today's plans.

  • It summarized both without trouble, mostly reusing the source's own sentences, and hovering over a bullet showed where in the original it came from.
  • Asking for a new summary of a bullet mostly rearranged the same wording.
  • Narrative and dramatic pieces came out as clipped sentences presented like facts, so it suits factual articles and papers better than stories.
  • The free tier then allowed three summaries a month, the number Basic includes today.
