The short answer
Editorial assessmentGrammarly compared with Wordtune
Wordtune and Grammarly overlap almost completely on rewriting and tone, and Wordtune's rewrite suggestions are often the more interesting of the two. Grammarly wins on breadth of surface coverage, correction depth, team administration, and price at scale. Wordtune is worth preferring only if you specifically want its rewriting model and do not need the Word add-in, desktop overlay, or team controls.
Choose Grammarly if
Small businesses and teams whose writing problem is quality and consistency across email, chat, proposals, and documents rather than volume of published articles, especially organizations with non-native English speakers, client-facing writers, or a support function that needs everyone to sound the same for $12 a seat.
Choose Wordtune if
Non-native English writers, consultants, academics, students, and anyone whose day is email and documents, who already writes plenty and wants it to read better, at a price low enough that the decision does not need a business case.

| Setup time | Under ten minutes for an individual: install the extension, sign in, and it works. A team rollout takes an afternoon to configure roles, groups, Knowledge Share entries, and Snippets, plus whatever time your IT policy needs for extension approval. | Five minutes. Install the extension, sign in, and it appears wherever you type. There is no configuration and nothing to train. |
| Learning curve | Almost none for correction, which is the point. The generative prompts and the Feature Management Hub take a little exploration, and the real skill is deciding which suggestion categories to disable so the tool stops flattening your writing. | Essentially none. Highlight text, pick a rewrite. The only underused parts are the summarization and counterargument tools, which most people never discover because the rewriting is so immediately obvious. |

Strengths and limitations
Grammarly
Strengths
- Distribution into the applications where writing actually happens, across browsers, desktop, Word, and mobile keyboards, which no article generator in this category comes close to matching.
- Fifteen years of tuning on correction quality, particularly for non-native English writers, where the fluency suggestions solve a problem generic chat assistants handle clumsily.
- Team governance features including roles, user groups, Knowledge Share, Snippets, and brand tones are included at the $12 Pro price rather than gated behind a separate business tier.
- A permanently free tier that is a complete correction product, so evaluation costs nothing and a large share of individual users never need to pay.
Limitations
- No model transparency and no model selection. Grammarly will not tell you which large language model handles which feature, which is out of step with the category in 2026 and makes quality changes impossible to reason about.
- Generation is weak relative to a frontier chat subscription costing $20, so the 2,000-prompt allowance is not the reason to buy.
- Zero long-form SEO capability: no SERP analysis, no keyword workflow, no CMS publishing, no bulk generation, no internal linking.
- The clarity engine homogenizes voice, and its suggestions are calibrated for business correspondence rather than for writing with a deliberate style.
Wordtune
Strengths
- Sentence rewriting is still the best in class, faster and more faithful to original meaning than asking a general assistant to rephrase, largely because the interaction is a keystroke rather than a prompt.
- The extension model means it works where you already write, in Gmail, Docs, LinkedIn, and CMS fields, rather than asking you to move to a new workspace.
- Pricing is genuinely low, with a usable free tier, a 50 percent annual discount, and a further 30 percent off for students, educators, and nonprofit staff.
- Summarization of documents, articles, web pages, and YouTube videos turns it into a reading tool as well as a writing tool, which most competitors ignore entirely.
Limitations
- It does not generate content from a brief. If your problem is the blank page, this is the wrong product entirely.
- English-only output. Translation goes from ten languages into English, but you cannot write natively in Spanish, German, or anything else, which rules it out for multilingual content teams.
- No brand voice training, no style guide, no knowledge base, and no meaningful team workspace, so it offers nothing to an organization trying to make several writers sound alike.
- No SEO, no publishing, and no integrations with content systems, so it sits entirely outside a content marketing workflow.
Pricing compared
Grammarly
Freemium per-member subscription with three billing cadences on the paid tier and a contact-sales enterprise plan; generation is metered by AI prompts rather than words.
- Free$0
- Pro$12
- EnterpriseCustom
At $12 a member on annual billing, Grammarly is fairly priced for what it uniquely does, which is correction and revision inside every application you already use, with team tone and snippet governance thrown in at no extra tier. Judged as a generative writing tool it is poor value: 2,000 prompts of an undisclosed model with no ability to choose it is a worse deal than a $20 frontier subscription, and the drafting quality is not competitive. The honest framing is that Pro is a $12 correctness and consistency layer with a generation feature attached, and it should be bought on the first half of that sentence. Free is genuinely usable and a large fraction of individual users never need to upgrade.
Wordtune
Freemium individual subscription metered by daily rewrites and monthly summarizations, with a separate business offering.
- Basic$0
- Advanced$6.99
- Unlimited$9.99
Wordtune is the least financially consequential purchase in this category. At $6.99 a month annually for unlimited rewriting, summarization, and grammar checking, it costs less than a third of a frontier model subscription and does one thing better than any of them, which is offering multiple faithful rephrasings of a sentence in one keystroke inside the tool you are already typing in. The value question is not price, it is fit: if your bottleneck is producing content, Wordtune will not help at all, and no discount changes that. If your bottleneck is that your writing does not read the way you want, it is close to free relative to the time it returns.
Editorial verdict on each
Grammarly
Grammarly is the only product in this category you buy for where it runs rather than for what it produces. The correction and revision layer is excellent after fifteen years of tuning, the fluency support for non-native English writers solves a real problem cleanly, and the 2026 repackaging put team roles, shared snippets, and brand tones at the $12 individual price instead of behind a business tier. Set against that: generation is the weak half of the product, there is no model transparency and no model picker, and nothing here helps you publish SEO articles. If you already pay $20 for a frontier assistant, Grammarly does not replace it and is not trying to; it complements it by working inside Gmail and Word where the assistant cannot reach. Buy it as a correctness and consistency layer for a team that writes a lot of email, support replies, and client documents. Do not buy it as an AI writer, and keep half an eye on the fact that the company now calls itself Superhuman and has already deleted one of its acquired brand names.
Read the full Grammarly profileWordtune
Wordtune is the most useful product in this category for the largest number of people and almost nobody thinks of it as an AI writing tool, because it does not write. It rewrites, and it does that better and faster than any general assistant because the interaction is a keystroke on a highlighted sentence rather than a prompt in another window. For non-native English speakers, consultants, students, and anyone whose job is email, $6.99 a month for unlimited rewriting, summarization, and grammar checking is close to a rounding error against the time it returns. The two honest cautions are scope and sponsor: it will not generate anything, produce SEO content, or make a team sound consistent, and AI21 Labs has visibly moved on to enterprise products with funding that stopped confirming in 2023. Try the free plan, and if you keep hitting the daily limit, go straight to Unlimited and skip Advanced.
