Grammarly vs Wordtune: Which AI Writing Assistant Should You Actually Pay For in 2026?
Two writing assistants, two very different jobs. One catches your mistakes, the other rewrites your sentences. We ran the same drafts through both and picked a winner, but the right one depends on what you actually struggle with.
For most people who write in English every day (emails, docs, reports, DMs), Grammarly is the safer pick. It catches more errors, works in more places, and Pro runs $12 a month, cheaper than Wordtune's top tier. But if your problem isn't grammar and you already know what you want to say, Wordtune is the better tool. Its rewrites are more varied, more context-aware, and non-native English writers in particular will get more out of it. Different jobs, different picks. Buy Grammarly to fix writing. Buy Wordtune to reshape it.
Round by Round
This one isn't close. Grammarly is built for this job and does it better. Wordtune offers grammar and spelling corrections, but independent testing has clocked it below Grammarly on accuracy, including missing some intentional spelling errors. In our runs, Grammarly flagged nearly every seeded error. Wordtune missed a handful, especially the trickier homophone swaps. If you need bulletproof grammar checking, Wordtune alone won't cut it.
Wordtune is decisively better at paraphrasing. It gives you context-aware sentence and paragraph rewriting that keeps the meaning while cleaning up clarity and flow, plus instant tone switching, sentence lengthening or shortening, and style adaptation. Where Grammarly typically hands you one correction, Wordtune hands you options: three or four phrasings of the same sentence, one sharp, one formal, one conversational. Grammarly Pro now includes full-sentence rewrites, but it isn't as sophisticated as Wordtune's dedicated rewriting engine.
Grammarly is genuinely everywhere. Its browser extension, desktop app, mobile keyboard, and native integrations cover essentially every place a normal person types on a computer. Wordtune integrates with Gmail, Slack, Google Docs, Outlook, and MS Word as a browser extension, which covers the important surfaces, but Grammarly's reach is broader and its inline experience is more polished. If you want one tool that follows you around all day, Grammarly wins.
Wordtune ships more useful extras for the average user. Its AI reading assistant can summarize articles, PDFs, and YouTube videos, and its Spices feature offers a dozen AI cues (analogies, statistics, quotes, jokes) for enriching writing, plus an AI humanization feature that reduces AI-detection flags. Grammarly counters with a real plagiarism checker (access to 16+ billion web pages and ProQuest's academic database), but it's gated to Pro and Enterprise, and it's only useful if you actually need to check for plagiarism. For the average writer, Wordtune's extras get used more often.
Both offer limited free plans, but Grammarly's is more generous for everyday use: a 100,000-character limit on the free plan versus Wordtune's 10,000, and Wordtune caps the free tier at around 10 rewrites per day and 3 summaries per month. On paid plans, Grammarly Pro is $12 a month billed annually ($144/year), and it held that price through the Superhuman rebrand in October 2025. Wordtune Premium plans start at $9.99/month, but Wordtune's earlier published tiers ran up to $19.99/month, which puts the top tier above Grammarly Pro. Grammarly is the better value at the top of each ladder.
Wordtune consistently wins this crowd, and our test group agreed. It's specifically praised by ESL writers who know their content is correct but want to sound more natural, and by professionals writing in a register that doesn't come naturally (technical writing for non-technical audiences, formal reports made more approachable). Grammarly will catch your mistakes. Wordtune will make you sound like yourself, only clearer. If your problem is expression rather than grammar, this is the round that matters.
Who should buy which
Pick Grammarly if you write in English all day and your main problem is catching mistakes before they go out: typos, comma splices, missing words, tone that comes across wrong in an email. It’s the safer default, it works everywhere you type, and at $12/month for Pro it’s the better value. It’s what we’d install on a new laptop before we did anything else.
Pick Wordtune if your problem isn’t grammar. If you know what you want to say but keep rewriting the same sentence three times trying to get it right, Wordtune cuts through that faster than anything else on the market. It’s the pick for ESL writers, marketers polishing copy, and anyone who works with tone for a living.
Plenty of writers we know keep both installed and let them do different jobs: Grammarly running in the background as a proofreader, Wordtune summoned on demand when a paragraph won’t come out right. At $12 and roughly $10 a month respectively, that combo is still cheaper than most productivity subscriptions.
What changed this year
Grammarly’s parent company rebranded to Superhuman in October 2025 after acquiring the email client of the same name. The product you know is unchanged (same browser extension, same grammar checker, same tone detection) and Grammarly Pro stayed at $12/month through the transition. A new Business tier at $33/month bundles Grammarly Pro with Superhuman Mail and Coda docs, but for individual writers it’s not the right plan. The standalone Pro plan is.
Wordtune’s pricing has drifted the other way. Premium starts at $9.99/month on the vendor’s own comparison page, though other tiers have historically run up to $19.99/month, so watch the checkout page carefully. The plan you land on depends on how you enter the funnel.
The short version
For most people, most days: Grammarly. For rewriting, tone shifting, and non-native English writers: Wordtune. If you can only afford one and you write mostly in English, start with Grammarly and add Wordtune later if your drafts keep coming out stiff. That’s the order we’d buy them in ourselves.
