Grammarly vs Wordtune
A plain-English comparison to help you choose between them.
A safety net against an editor. Grammarly lives where you type, browser to Office, catching errors in real time and rewriting for clarity and tone, now under the Superhuman company with AI drafting alongside; Wordtune reshapes sentences that are already correct, offering alternatives across tones and lengths, chosen by you, for writing that has to stay recognisably yours. Pick Grammarly when the first job is catching what is wrong wherever you write; pick Wordtune when the words are right but you want each sentence to carry better, and note that plenty of writers run both.

- Data
- For confidential writing, check enterprise/DPA terms before pasting sensitive content; consumer tiers process text on Grammarly/Superhuman servers. Human-review AI rewrites for accuracy and voice. Note "Superhuman" is now the parent company: verify which product/tier you are buying, as stale listings cite retired "Starter" pricing.
- Summary
Wordtune is AI21 Labs' writing companion, built around rewriting rather than generating: take a sentence you have already written and see it again in different tones and shapes, casual to formal, shorter to expanded, until one says it better.
- Best for
- Rewriting your own sentences across tones and lengths
- Choosing between suggested alternatives rather than accepting prose
- Spelling and grammar checking alongside the rewrites

Common questions
Is this an either-or choice?
Less than most comparisons on this site. Grammarly is ambient, checking everything you type across browser and desktop; Wordtune is deliberate, invoked on sentences you want reshaped. They overlap on rewriting suggestions, but the daily jobs differ enough that running both is a common and coherent setup.
Which changes my writing more?
Wordtune, by design. Grammarly's default posture is corrective, fixing errors and tightening phrasing while leaving your structure alone. Wordtune's whole offer is alternatives: shorter, expanded, more formal, more casual versions of your sentence. If preserving your voice matters, choosing between its options keeps you in control.
Which jobs do both of them refuse?
Neither is a drafting tool at heart, though Grammarly now adds generation under the Superhuman umbrella. Long-form drafting from a brief belongs to the general assistants. Team governance, terminology enforcement and brand voice at scale belong to the writing platforms built for organisations rather than individuals.
