Wordtune

Where Wordtune sits

Wordtune is one of the longest-running AI rewriting tools on the market, and reviewing it in late 2026 means reviewing two things at once: the product, and the company standing behind it. Wordtune launched in October 2020 as the consumer flagship of AI21 Labs, the Israeli model developer, and it grew into one of the defining sentence-level writing assistants, with AI21 claiming roughly 10 million users and more than 782 million rewrite suggestions served as of August 2025 (recatools.com). The premise was always narrower than the "AI writer" category that grew around it: not generating content from scratch, but rewriting what you already wrote so it reads better while keeping your meaning.

The status question matters more than any feature comparison right now. In April 2026, Calcalist reported that AI21 Labs had discontinued development of Wordtune to focus on Maestro, its enterprise agent platform, and Globes reported in May 2026 that the company was laying off around 110 of its 180 employees (teknexiahub.com). Some trackers date the consumer-product shutdown to April 2025 and describe Wordtune as discontinued outright (benched.ai), while others record no shutdown at all (effecthub.net). When I checked wordtune.com/plans myself at the time of writing, the site was live, selling subscriptions, and showing no notice of any change. My read: Wordtune is still operating and still charging cards, but new features are unlikely and the parent company is in a documented restructuring. I would not commit to a long annual billing cycle.

What Wordtune actually does

The core is rewriting. You highlight a sentence or paragraph and Wordtune offers alternative phrasings, with modes for casual and formal registers plus shortening and expanding. The pitch is that it works from meaning rather than swapping synonyms, and in practice that is mostly true — more on that below. Around that core sit several adjacent tools: a summarizer that handles documents, articles, webpages and YouTube videos; inline "Spices" that can insert examples, statistics, counterarguments or conclusions into your draft; and spelling and grammar correction that runs even on the free plan.

At time of writing, wordtune.com/plans lists three tiers. Basic is $0 with 10 rewrites and AI suggestions per day, 3 AI summaries per month, and unlimited spelling and grammar fixes. Advanced costs $6.99 per month billed annually and raises usage to 30 rewrites per day and 15 summaries per month. Unlimited costs $9.99 per month billed annually and removes the caps entirely, adding vocabulary enrichment, clarity and fluency tools, and premium support. There is a 3-day free trial on paid plans that requires payment details (wordtune.com/plans). Wordtune offers no refunds, though students, educators and non-profit staff with valid credentials can get a 30% discount through support. Third-party pricing trackers disagree slightly about monthly versus annual billing (aipedia.wiki reports a cheaper effective annual rate), so read the checkout screen before paying. Business features such as SAML SSO and centralized billing are listed but sold through conversations with AI21, and the former Plus and Teams tiers were retired in a 2026 pricing rebuild (aipedia.wiki).

Platform coverage is decent: web editor, browser extensions for Chrome, Edge, Firefox and Arc, and an iPhone app with a keyboard that works in most writing apps (teknexiahub.com). There is no Android app and no Safari extension, and the Mac desktop beta has been discontinued.

My testing notes

I put Wordtune back through my standard rewriting gauntlet this month. Three observations stand out.

First, rewrite quality remains genuinely good. I fed it a 250-word passage of my own review prose, deliberately packed with hedges and product names, and the formal-mode rewrites preserved register and named entities instead of flattening them. The shortening mode cut roughly 30% of word count while keeping every caveat I had written — that is the behavior I care about in an editing assistant, and it is where synonym-shuffling paraphrasers still fail. The casual mode occasionally over-colloquialized ("In my testing" became "When I tried this out"), which I would not ship in editorial copy.

Second, the free plan's 10 rewrites per day evaporate within a single editing session. I burned the entire daily allowance in about twenty minutes of normal paragraph-level revision. The cap is per day, not per month, so a committed writer can still get light free use, but it functions as a trial rather than a free tier.

Third, the summarizer is the feature I would miss most. Summarizing a 20-minute YouTube review video into coherent bullets worked better than I expected and saved me a rewatch, though it surfaced conclusions while missing the caveats I had flagged verbally near the end of the video. The Chrome extension was also occasionally sluggish about detecting editable text inside Google Docs, while working immediately in Gmail and Notion.

How it compares in practice

The three tools I get asked about most in this category are Wordtune, QuillBot and Grammarly, and after running the same passage through all three again this month, the differences are still fairly clean. QuillBot Premium offers more rewrite modes and stronger value on paper at a similar price point, and its free summarizer covers 1,200 words without a subscription (aipedia.wiki). Grammarly Pro is the strongest grammar and spelling engine of the three and has absorbed much of the rewriting use case through its generative features, at roughly $12 per month billed annually. Wordtune's remaining edge is voice preservation: its rewrites kept my hedging and register intact more consistently than either competitor in my passage test, and its inline Spices suggestions for inserting examples or counterarguments have no direct Grammarly equivalent. Its summarizer is weaker than QuillBot's on raw documents but uniquely covers YouTube videos.

There is also the elephant in the room: general chat assistants. ChatGPT or Claude will rewrite a sentence on request, and millions of people already pay for them. What they do not do is sit inside your editor offering one-click alternates with a keyboard app on iPhone, which is the workflow Wordtune still owns for people who write all day. The 2026 pricing rebuild, which collapsed a four-tier ladder into Basic, Advanced and Unlimited and retired the Plus and Teams SKUs (aipedia.wiki, comparedge.com), suggests AI21 itself sees the product as a settled consumer cashflow line rather than something to invest in. Compared against that backdrop, the $6.99 entry price is reasonable for what is here, and the annual discount is meaningful — but I would pay monthly, not annually, given everything else I have said about the company.

Where it falls short

Wordtune is sentence- and paragraph-level. There is no long-form generation, no brand-voice training, no plagiarism checking, and no way to build a content workflow. The retired Teams SKU means there is no real self-serve team administration on the current ladder; multi-seat buyers are pushed into an enterprise conversation with a company that is visibly deprioritizing this product. Android users are simply not served. The 3-day trial requires a card, refunds are explicitly not offered (wordtune.com/plans), and third-party reviews note a pattern of billing and cancellation complaints that a maintenance-mode product is unlikely to fix quickly (recatools.com). Most importantly, the single biggest limitation is not in the product: nobody is meaningfully improving it. General chat assistants have absorbed much of what once made Wordtune distinctive.

Verdict

Rated 3.1 overall — the rewriting and summarizing core still earns strong marks for functionality depth and usability, but value and reliability signals take real damage from the no-refund policy and a parent company in restructuring, and the support/ecosystem score reflects a product nobody is building anymore. If you already pay for it and it fits your editing habits, keep using it while it lasts. If you are choosing a writing assistant today, I would pick something with an active maintainer and migrate on your own schedule rather than an acquirer's.
