This Wordtune review covers AI21 Labs’ writing assistant, which suggests rewrites of a sentence or paragraph as you type, with controls for tone and length. Wordtune, for example, also summarizes documents and checks grammar.
Its free plan allows 10 rewrites a day, and paid plans cost about half as much on yearly billing. However, AI21’s terms let it train on what you type unless you have a separate written agreement.
Wordtune Review: Is It Worth It in 2026?
For people who want quick sentence-level rewrites in the browser, often yes. Advanced also costs $6.99 a month billed yearly, below Grammarly Pro at $12. Our list of the cheapest useful AI tools covers other low-cost plans.
For confidential writing or long drafts, other tools fit better. Our list of the best AI for writing ranks the main options.
What Wordtune Does
First, you select a sentence, and Wordtune offers several rewrites, plus options to shorten, expand or change tone. It also summarizes documents and fixes grammar and spelling, for example.
Paid plans, moreover, add paraphrasing, fluency and vocabulary suggestions. Our guide to using AI for editing shows where such tools fit.
What Wordtune Costs
In addition, Wordtune sells three self-serve plans and a Business plan, as trackers read its pricing page in July and August 2026.
| Plan | Price | Limits |
|---|---|---|
| Basic | $0 | 10 rewrites a day; 3 summaries a month; unlimited grammar checks |
| Advanced | $13.99/mo, or $6.99 yearly | 30 rewrites a day; 15 summaries a month |
| Unlimited | $19.99/mo, or $9.99 yearly | No rewrite or summary caps |
| Business | By quote | SSO, admin controls, central billing |
Yearly billing roughly halves the monthly price, as our guide to annual vs monthly AI subscriptions explains. Note, however, that 30 rewrites a day on Advanced can run out in one long editing session.
Accuracy
However, we found no independent test of Wordtune’s rewrites. Rewrites, therefore, can shift meaning or flatten your voice, so read each one before accepting it.
Our guide to writing with AI without sounding like AI covers voice.
Your Data
AI21’s terms say it may use inputs, outputs and other data to train its models unless you sign a separate written agreement that prohibits it, a policy analysis by ConductAtlas reports. You can email AI21 to request deletion.
Therefore, keep confidential text out of Wordtune on standard plans. Our guide to which AI tools train on your data compares other tools.

Wordtune vs Grammarly and QuillBot
Grammarly, for example, checks text across apps and lets individuals switch training off, as our Grammarly review covers. QuillBot, by contrast, focuses on paraphrasing with a 125-word free limit, as our QuillBot review explains.
General assistants such as Claude, however, rewrite whole drafts, as our guide to Claude for writing covers.
Who Should Use Wordtune
Overall, this Wordtune review finds it suits students, non-native English writers and professionals who want quick rewrites of single sentences. It also suits light users on the free plan. Our Grammarly vs Wordtune comparison also weighs price and data terms.
By contrast, however, it suits confidential work and long-form drafting less. Our list of the best AI tools for writers covers alternatives, and our list of the best AI for students covers study tools.
How We Research
This Wordtune review takes plans from trackers that read wordtune.com/pricing in 2026, and data terms from ConductAtlas’s analysis of AI21’s terms.
However, we did not read AI21’s terms directly or find an independent test of the rewrites. Our about page explains the criteria.

Wordtune
Quick sentence rewrites, broad training terms
Wordtune rewrites sentences as you type, with tone and length controls, a free plan and Advanced from $6.99 a month yearly. Against that, daily caps bind on Advanced, there is no independent test, and AI21’s terms allow training on your text without an enterprise agreement.
The Verdict
Overall, Wordtune is a quick, cheap way to rework single sentences, and its free plan covers light use. Its data terms, however, are broader than most writing tools we review.
The rest of this Wordtune review sets the score at 3.1. So use it for non-sensitive text, and pay yearly only if you rewrite daily.
