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.

Side by side
- Summary
Grammarly is the writing assistant that lives where you type: browser, desktop, mobile, Google Docs and Microsoft Office. It catches errors in real time, rewrites for clarity and tone, and now adds AI drafting plus agents for humanising machine text and detecting it.
Its company is now Superhuman, uniting Grammarly with the Coda workspace and the Mail inbox under one suite, threaded together by a proactive assistant. The Grammarly product itself continues under its own name as the writing layer, on free and paid tiers.
MoreLess
Its enduring value is the safety net: a constant editorial pass over everything a person or a team writes, everywhere they write it.
- Best for
- Real-time grammar, clarity and tone checking across nearly every app
- One-click rewrites that tighten without changing meaning
- A steady editorial register for teams and non-native writers
- AI drafting where you already type, not in a separate app
- Checking whether text reads as human or machine-made
- Cost
- Freemium (Free tier + paid plans)
- Ease
- Openness
- Hosted service
- 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. Suggestions arrive as alternatives to choose between rather than prose to accept, which keeps the writer's judgement in the loop.
Around the rewriting core sit spelling and grammar checks, AI summarisation of longer material, and browser and editor integrations that bring the suggestions to where writing happens. A free tier covers light use within daily and monthly allowances on the AI features; paid tiers lift the limits.
MoreLess
It suits people who write plenty and want their own sentences improved, not replaced. AI21's own marketing now leads with its enterprise model business, but Wordtune remains live, priced and signup-open as its consumer writing product.

By area
Where each one pulls ahead, area by area.
| Area | Grammarly | Wordtune |
|---|---|---|
| By job | ||
| Getting started | Grammarly gives many people their first concrete proof of AI assistance: watching a clumsy sentence get reworked in the place they were already typing | Wordtune teaches what AI suggestion feels like without the blank-page delegation that makes new users distrust generated prose, because it never takes the pen |
| By task | ||
| Writing & research | Grammarly is a constant editorial safety net rather than a sentence workshop, holding tone steady for a chosen audience across everything typed | Wordtune reworks an application or a bio sentence by sentence, and fixes the grammar without changing the voice it was written in |
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.
