Wordtune and Grammarly both live in your browser and both improve your writing, but they solve different problems. Wordtune is a rewriting specialist — highlight a sentence and it offers several natural phrasings. Grammarly is an all-round editor — grammar, spelling, tone, plagiarism and whole-document checks. Pick Wordtune to rephrase and vary tone; pick Grammarly for comprehensive correctness. Plenty of writers run both.

The case for Wordtune
Wordtune wins the moment your problem is "this sentence is fine, but it could be better." It returns multiple phrasings instantly and lets you steer each toward casual, formal, shorter or longer. That's more useful than a single suggested edit when you're hunting for the right voice, and a benchmark put its intent-preservation at about 95% versus Grammarly's 92%.
It's also the stronger tool for non-native English writers, because seeing several natural versions of a sentence beats guessing which one a native speaker would use. The catch is scope: no plagiarism checker, a lighter grammar engine, and it isn't built to draft long-form. Full detail in our Wordtune review.
The case for Grammarly
Grammarly is the more complete tool. Its grammar, spelling and punctuation engine is deeper, it checks entire documents rather than one sentence at a time, and it layers in plagiarism and AI-text detection that Wordtune simply doesn't have. In 2026 it folded Premium and Business into a single Pro plan that covers individuals and teams up to 149 members, with full-sentence rewrites, tone adjustment and 2,000 AI prompts per member per month.
It's the more conservative editor too — roughly 98% factual alignment in testing, meaning it's less likely to change your meaning while fixing your prose. If you want one tool that keeps a whole document clean, correct and original, it's Grammarly. See the Grammarly review for the full picture.
Pricing head-to-head
Both have genuinely useful free tiers, and both are affordable paid. Wordtune is the cheaper of the two on its top plan.
| Wordtune | Grammarly | |
|---|---|---|
| Free | 10 rewrites/day, 3 summaries/mo | Grammar, spelling, basic tone |
| Entry paid | Advanced — $6.99/mo annual | — |
| Top individual | Unlimited — $9.99/mo annual | Pro — $12/mo annual ($30 monthly) |
| Teams | Custom (SSO, admin) | Pro covers teams to 149; Enterprise custom |
Wordtune's Unlimited at $9.99/month undercuts Grammarly Pro at $12/month, but they're not buying the same thing — one is unlimited rewriting, the other is full-document editing plus plagiarism. Compare the tiers in our Wordtune pricing and Grammarly pricing guides.
Which should you pick?
Pick Wordtune if your main need is rephrasing, tone control or writing more naturally in a second language. It's cheaper, sharper at its one job, and the multiple-phrasing approach is a genuine daily unlock for editors and non-native writers.
Pick Grammarly if you want one tool that keeps entire documents correct, original and consistent — grammar, plagiarism, AI detection and team controls in one place. And if budget allows, running both is a legitimate answer: Grammarly to catch and check, Wordtune to phrase.
