Grammarly is worth keeping for most people. Here's who should switch, and to what.

You’re not here because you’re curious about grammar checkers. You’re here because you’re paying for one and something about it has started to bother you. Maybe it was the renewal charge. Maybe it was the extension slowing down a text box. Maybe you looked up one day and the company had a different name.

I went looking properly, and with a declared interest. I co-founded Subtext, an app that reads the emotional tone of personal messages, so I work next to this market without competing in it. I read the policy pages themselves, checked prices at the checkout, and pulled the actual court filing. That happened on 17 August 2026, and I came back on 16 September 2026 to recheck Grammarly’s language support, Wordtune’s prices and Hemingway’s grammar checking.

The conclusion surprised me a bit. For most people reading this, leaving is the wrong move. But for a few specific groups it’s the right call, and the usual lists rarely say which.

One more word on that interest. Reading how a personal message will land is the one job none of the tools below is built for, and Subtext isn’t a grammar checker and won’t replace yours, so I have no horse in the Grammarly race itself (the direct comparison is in Subtext vs Grammarly for personal messages and tone checking), but I do have a stake in this space. Check the prices and policy pages yourself rather than taking my word for them.

If you only read one section

Stay if you use Grammarly the way most people do, which is to say everywhere at once. It works in your browser, your email, your Slack, your phone keyboard and your Word documents from a single install, and nothing else comes close to that. Switch to annual billing at $12 a month and turn off the training toggle, and most of the reasons people cite for leaving stop applying.

Leave, or at least test first, if much of your week is in another language. Grammarly now checks grammar and spelling in more than 20 languages besides English, still labelled beta, and how far its suggestions go beyond that depends on the language. If half your week is in German or Turkish or Spanish, run a week of your real writing through it before you renew.

Leave if you write long things. Books, dissertations, reports. Grammarly is built for sentences, and ProWritingAid is built for manuscripts.

Consider leaving entirely if you own a recent iPhone or already pay for Microsoft 365 or Google Workspace, because the free tools built into those now cover more than you’d expect.

Leave, or rather add something else, if the messages that cost you time are personal rather than professional. Every tool in this post is tuned mainly for clear and professional writing. None of them is built to tell you how a message to your sister will land. If that’s your problem, the better question is what’s the best AI writing assistant for text messages. That gap is why I ended up building Subtext, so weigh what I say about it accordingly.

Everything after this is me showing my working.

Grammarly is called Superhuman now, and it’s been an eventful year

On 29 October 2025 the parent company rebranded to Superhuman¹, pulling Grammarly, the Coda workspace and Superhuman Mail under one name and launching an agent called Superhuman Go. The writing product is still called Grammarly. The plans changed, though. Premium and the old Business plan were folded into a single tier called Pro.

Then two things happened, and I think you should know about them before you renew.

On 11 March 2026, investigative journalist Julia Angwin filed a class action² over a feature called Expert Review, which had launched the previous August. It generated writing feedback and attributed it to real, named journalists and authors who had never agreed to any of it. The case is Angwin v. Superhuman Platform, Inc.³, No. 26 Civ. 02005-JGK, in the Southern District of New York. Grammarly disabled the feature the same day. Angwin’s lawyer said he’d since heard from 40 to 50 more people who objected to being included.

CEO Shishir Mehrotra apologised on LinkedIn, and later told TechRadar⁴ that the feature wasn’t good for experts or for users, while also saying the lawsuit is without merit and that the feature had been pulled before the filing.

Then on 23 June 2026, Superhuman acquired GPTZero⁵, the AI detection company, which had around 19 million registered users.

Why the GPTZero deal matters if you’re a student

The company selling you writing help now owns two of the main tools for catching AI writing. I don’t think that’s sinister. I do think you should know how badly detectors perform on some people’s writing.

The reference study here is Liang et al., published in Patterns in July 2023⁶. Five Stanford researchers ran seven widely used GPT detectors against two sets of human-written essays: 91 TOEFL essays written by non-native English speakers, and 88 US eighth-grade essays from the Hewlett Foundation’s ASAP dataset. Accuracy on the eighth-grade essays was near perfect. On the TOEFL essays, the detectors misclassified more than half as AI-generated, at an average false positive rate of 61.22%. All seven detectors agreed on 18 of the 91 essays. At least one detector flagged 89 of the 91.

The number Liang et al. tested seven widely used GPT detectors on 91 TOEFL essays written by non-native English speakers. The detectors misclassified more than half as AI-generated, at an average false positive rate of 61.22%.

The mechanism is the uncomfortable part. Non-native writers use less linguistic variation, which produces lower text perplexity, which is exactly what perplexity-based detectors read as machine-written. Asking ChatGPT to enrich the vocabulary in those same essays made the flags mostly disappear.

To be fair to the other side, GPTZero published a response in October 2023 arguing that ESL bias in detection was an outdated narrative, and shipped an updated model. A technical report from Pangram⁷, a company that sells a competing detector, put the new model’s false positive rate on that same TOEFL benchmark at 7.7%, or 1.1% if borderline results are read generously. Much better, if you take a rival’s numbers at face value. Still not zero, on a benchmark the model’s builders knew about.

Two practical takeaways. Grammarly’s Authorship feature works differently from all of this, because it watches typing and paste events while you write instead of analysing a finished document, which makes it a far more defensible way to demonstrate you wrote something. And if you’re a non-native English speaker, keep your drafts.

Why people cancel, in order of how often it comes up

I went through the review aggregators and forums instead of guessing. The pattern is consistent.

Billing is the number one complaint, by a distance. Not features. Billing. Subscriptions auto-renew, refunds are issued only where legally required, and you can’t cancel from mobile. You can see it in the gap between the ratings. Grammarly holds 4.7 out of 5 on G2⁸ across 12,969 reviews and 4.7 on Capterra across 7,210, but 3.5 on Trustpilot across 10,394. G2 and Capterra skew toward business users who didn’t personally get charged. Trustpilot is where consumers go when a card gets debited unexpectedly.

The price gap between billing cycles. Pro is $12 a month on annual billing, $20 a month if you pay quarterly, and $30 a month if you pay monthly⁸. That’s a 2.5x spread for the same product. A lot of people who feel ripped off are on the wrong cycle.

Over-correction. Grammarly pushes toward short sentences, active voice and formal neutrality. For a work email that’s exactly right. For anything with a voice, it sands the edges off. This complaint comes almost entirely from people writing fiction, essays or anything personal.

The browser extension. Input lag, conflicts with rich-text editors, the widget sitting on top of the text box. I take this seriously because Grammarly’s own engineering team publishes about text input lag⁹ as a tracked performance metric, and because the conflicts show up in developer bug threads. Slate.js, the editor framework behind a lot of modern web apps, has an open discussion¹⁰ about exactly this.

Privacy defaults. If you’re on Free, Premium or a single-user Pro account, the training toggle is on by default¹¹. Enterprise and education accounts are opted out automatically. You can switch it off at account.grammarly.com/security/privacy if you’re on Free or Premium, or at account.grammarly.com/admin/data_settings if you’re on Pro, and it takes about ten seconds either way.

Beyond English, Grammarly’s coverage is newer and uneven

Grammarly’s English is still its deepest, with American, British, Canadian, Australian and Indian variants. Since September 2025¹² it has added grammar and spelling checks in more than 20 other languages, German, Spanish and Turkish among them, and it still calls that support a beta¹³. Its languages page¹⁴ lists the deeper clarity, tone and paragraph rewrite suggestions only for Spanish, French, German, Italian and Portuguese besides English, while that help article lists clarity suggestions for most of the others. Outside English, Grammarly says it doesn’t yet tell regional variants apart.

I live in Berlin. Roughly half of what I write in a given week isn’t in English, so the first thing I’d test before renewing is a week of my real writing, in each language. Language coverage mattered enough to me that Subtext works in 17+ languages. I’ve read a dozen “best Grammarly alternatives” articles while researching this and almost none of them say how deep any tool goes outside English, which tells you something about who writes those articles.

If you’re multilingual, the question has moved on from whether Grammarly covers your languages at all to how deep it goes in each one, and your own writing will answer that faster than any comparison post, this one included.

What Grammarly still does better than everyone else

I want to be fair here, because the case for staying is stronger than the internet suggests.

It’s everywhere from one install. Browser, Windows, macOS, Word, Google Docs, and keyboards on iOS and Android. It overlays custom input fields in things like Salesforce, Jira and Zendesk without you copying text anywhere. Every alternative below is worse at this. Most are much worse.

The mobile keyboards. If you write seriously on your phone, this is the feature you’ll miss within a day of leaving.

Plagiarism checking is bundled. ProWritingAid sells manuscript analysis as separate Story Credits that sit outside every subscription tier¹⁵, which is a cost people don’t notice until they need it.

Authorship. As above, it’s process-based, which puts it in a different category from the detectors that produced those 61% false positives.

It’s good for ESL writers and people with dyslexia. Always-on correction in every app, without having to decide to go and use a tool, is a different experience from opening an editor. Don’t underestimate how much of the value is in never having to think about it.

The alternatives, sorted by what you’re trying to do

I’ve grouped these by job instead of ranking them, because a ranked list of writing tools is close to meaningless. The right answer depends entirely on what you write.

LanguageTool, if you write in more than one language

Grammar, spelling and style across 30-plus languages, which is the main reason to be here. Premium starts around $4.99 a month on annual billing, and LanguageTool’s own help pages list €19.90 a month¹⁶ for monthly billing and €56.90 per user per year for teams.

One change matters more than the price. The browser extension is now Premium-only¹⁷, with checks up to 100,000 characters, which LanguageTool’s own help centre describes as significantly more than the former free limit. If your plan was to leave Grammarly for LanguageTool’s free extension, that plan expired. The free web editor and the API still exist, and the API documentation¹⁸ puts free requests at 20,000 characters and Premium at 60,000.

The real feature is that the core engine is open source and you can self-host it, which means your text never leaves your own infrastructure. Grammarly doesn’t offer that.

Most reviews skip the fact that LanguageTool is owned by Learneo, the same company that owns QuillBot. The privacy policy at languagetool.org¹⁹ is the Learneo policy, stamped as updated 17 August 2026 as of this writing. If the date stamp reads later than that when you check it, the policy has changed since. I’d have preferred a simpler answer here, but that’s the answer there is.

It doesn’t do tone detection at Grammarly’s depth, plagiarism checking, or anything agentic.

ProWritingAid, if you write books

Twenty-five-plus reports on pacing, dialogue tags, sentence variety, repetition and readability. It integrates with Scrivener, which no other tool on this list does properly.

Pricing changed significantly in 2026 and the old numbers are still circulating. The free plan is now capped at 500 words per check, Premium costs $30 a month or $120 a year²⁰, Premium Pro $36 a month or $144 a year, and lifetime licences $399 for Premium and $699 for Premium Pro. The annual price rose 52% from $79, which SaaS Price Pulse tracked across 18 pricing snapshots²¹ since November 2025.

The lifetime licence is the interesting one. At $399 against $120 a year, it pays for itself somewhere in year four.

It doesn’t do fast real-time correction. It’s slower than Grammarly and report-heavy. You use it after the draft exists, in deliberate passes, and it has no team management. Refunds are three days on annual and lifetime plans, and monthly plans aren’t refundable at all.

QuillBot, if you rewrite constantly (with a warning)

Paraphrasing in nine modes, summarising, grammar checking, citation generation. Free tier caps paraphrasing at 125 words with two modes. Premium is $19.95 monthly or $99.95 annually²², which works out to $8.33 a month, with a student rate around $6.25.

Now the warning, and this is the part I’d want to know. QuillBot changed its privacy policy on 8 November 2025. Its own help centre states plainly that it previously asked for consent²³ to store your text inputs and will no longer require it, storing inputs for all extension users by default. There are now two separate controls: storage, which everyone can opt out of, and training, which only account holders can opt out of. Team Plan inputs are excluded²⁴ from training.

So if you’re leaving Grammarly over privacy and landing on QuillBot, you’ve moved in the wrong direction. That’s not a knock on the product, which is good at what it does, but the grass isn’t automatically greener.

Hemingway, if you want your sentences shorter

Highlights long sentences, passive voice and adverbs, and gives you a readability grade. The web app is free. The desktop app is $19.99 as a one-time purchase. Hemingway Editor Plus, which adds AI rewriting, is $10 a month or $100 a year²⁵ according to Hemingway’s own billing pages, working out to $8.33 monthly on the annual plan.

Editor Plus now checks grammar and spelling too, but readability is the core job. I’d pair it with something else instead of treating it as a replacement.

DeepL Write, if you work across languages professionally

Rephrasing and refinement from the translation company, strongest on European language pairs. Write Pro is $7.49 per user per month²⁶ on annual billing as an add-on to Individual and Team plans, and included at no extra charge in Business and Enterprise.

Contrary to what I’ve seen repeated everywhere, DeepL’s free tier is not private. DeepL’s terms state that free-tier text is retained for a limited period to train and improve their neural networks, and the free terms prohibit submitting personal data at all. Paid tiers delete text after processing and never use it for training. Several comparison articles present DeepL as blanket privacy-safe. That’s only true if you’re paying.

Wordtune, if you rephrase sentences

Contextual rewriting with tone controls. The free plan gives you 10 rewrites a day. Advanced is $6.99 a month, or $4.89 a month on annual billing²⁷, and Unlimited is $9.99 monthly or $6.99 a month on annual billing, though Wordtune’s prices vary by region.

Two things the comparison posts get wrong. It’s a browser extension plus a web app plus an iOS app, with no proper Word or Google Docs plugin, and the rewriting output is English-focused with no multilingual rewriting despite the translation features. Also, its Traceless mode, the one that deletes your input seconds after generation, is a Business and Enterprise feature²⁸. Individual subscribers don’t get it.

Trinka or Paperpal, if you write academic work

Trinka is built for academic and technical English and has a free tier. Paperpal is broader and covers more of the submission workflow. Both handle the conventions of research writing that general tools flatten. I could only find current pricing for these through third-party trackers, which put Trinka in the region of $7 a month and Paperpal around $25, so check their own pricing pages before you commit.

Vale, if you write documentation

Free, open source, and it lints prose the way a linter checks code. It enforces a style guide across Markdown and text files in your CI pipeline. No character limits, no subscription, no cloud. If you work in docs-as-code, it’s the correct answer and it isn’t close.

Possibly nothing, if you already own the ecosystem

This is the section I’d have wanted someone to write for me.

Apple Intelligence Writing Tools are built into iOS 18.1 and macOS Sequoia 15.1 onward, on supported hardware²⁹, meaning iPhone 15 Pro or any iPhone 16, plus M-series iPads and Macs. Proofread, Rewrite and Summarize work in most text fields including third-party apps, and language support expanded to 16 languages³⁰ with the iOS 26.1 update in November 2025. Processing happens on-device with heavier requests going to Private Cloud Compute.

They have no underlines as you type the way Grammarly does, no plagiarism check and no team style guides, and the rewrites are conservative.

Microsoft Editor covers basic spelling and grammar free in Word and Edge. The deeper Copilot features need a paid Microsoft 365 licence, and Microsoft’s own comparison page³¹ spells out what the free version leaves out.

Google Docs has free spelling, grammar and Smart Compose. “Help me write” and the tone controls come through Gemini, included in Workspace Business Standard³² at about $14 per user per month and above. Business Starter at around $7 gets very little.

If you’re on an iPhone 16 writing casual emails and messages, you may be paying $144 a year for something your phone already does. Every phone rewrites your messages now. Test it for a week before you renew.

The privacy section, where the results are not what you’d expect

I went into this assuming Grammarly would come out worst. It didn’t.

My summary is that Grammarly’s default is opt-out and the toggle is easy to find. QuillBot moved from opt-in to opt-out during this period, which is a regression. DeepL’s free tier is the one I’d warn people about, because a lot of people paste work documents into it assuming otherwise.

If privacy is your reason for leaving Grammarly, the only two answers that fully deliver are self-hosted LanguageTool and Apple’s on-device processing. Everything else is a matter of degree.

Why every “best Grammarly alternatives” list ranks ProWritingAid first

I checked this because the uniformity was suspicious.

Almost all of these articles are affiliate-monetised. LanguageTool’s programme pays up to 50% per sale³³ plus about $1.10 per lead through Awin. QuillBot pays 10% to 20%³⁴ on a recurring basis through PartnerStack. Grammarly itself pays³⁵ $0.20 per free signup and $20 per premium sale. ProWritingAid pays $0.25 per free sign-up and 5% per sale³⁶, on a 30-day cookie.

Now look at that list again. ProWritingAid pays the least of the four and ranks first almost everywhere, which means commission rate isn’t what’s driving the order. What ProWritingAid has is negotiated reader discount codes, and those indicate a direct relationship with the publisher instead of a generic network link. Kindlepreneur routes through a cloaked /click/ProWritingAid/ redirect. DemandSage ranks it first while promoting a Grammarly discount. SoftwareTestingHelp offers a reader-specific ProWritingAid code.

None of that makes ProWritingAid a bad tool. It’s an excellent tool for novelists. It just means the “#1 pick” label is describing a business relationship, not a test result.

The other tell is stale pricing. A lot of these articles still list ProWritingAid at $79 a year, which hasn’t been true since early 2026²¹. If a comparison post has the wrong price, nobody has opened the product recently.

For what it’s worth, there are no affiliate links in this post, and I have nothing to sell you from this list.

What none of these tools do

This is the part I found most interesting, because the gaps are consistent across every single tool.

Structure across a long document. Most of them work sentence by sentence, and ProWritingAid sells its manuscript analysis separately. None of them is built to tell you that chapter four should come before chapter three.

Consistency across a set of documents. Keeping terminology and style aligned across forty files is barely solved. Vale and PerfectIt get partway there.

Regional and dialect variation. Every tool normalises toward a standard register, which means valid regional English gets flagged as wrong. If you write in Nigerian English, or another variety your tool doesn’t list, you’ll spend a lot of time dismissing suggestions.

Domain precision. No editor validates a live statutory citation or checks specialist medical terminology against a current clinical database. In law and medicine you still need a human.

Emotional tone in personal messages. This is the gap I care about most, and it’s the reason I ended up building in this space. Every tool on this list optimises first for “professional and clear.” None of them is built for the message where clear isn’t the problem. The one where you need to set a boundary without sounding cold, or say the hard thing without the three apology paragraphs at the end. Grammar checkers tell you a sentence is passive. They don’t tell you it reads as passive-aggressive.

That’s the job Subtext does. Paste your draft or screenshot the thread so it reads both together, and it tells you how the message is likely to land on the person about to read it, names the wording creating that impression, then offers versions that fix it, the first one staying close to your own words. It works in 17+ languages. Try Subtext in your browserGet the appTry Subtext in your browser

I’d sooner say plainly that this is a different job than pretend it belongs on the list above. If what you need is a grammar checker, buy a grammar checker. The two solve different problems and most people writing seriously end up wanting both.

So, stay or go?

Stay if you write across many apps, you rely on the phone keyboard, you’re an ESL writer or have dyslexia and want always-on help, or you need admin controls and authorship evidence. Switch to annual billing and turn the training toggle off, and you’ve addressed most of what people complain about.

Go if your other languages don’t hold up in that test week, go to LanguageTool. If you write books, go to ProWritingAid, and buy the lifetime licence if you’re sure. If you paraphrase constantly, QuillBot, with the privacy settings changed on day one. If you work across languages professionally, DeepL Write Pro, and never the free tier for anything confidential.

Go nowhere if you own a recent iPhone or already pay for Microsoft 365 or Google Workspace and your writing is mostly casual. Try the built-in tools for a week first.

Add Subtext if the writing that costs you time is the personal message rather than the professional document. It sits alongside a grammar checker and doesn’t replace one.

If you’re mid-cancellation right now, I’d push back on one thing. Check which billing cycle you’re on before you decide the price is the problem. A surprising number of people leaving over $30 a month are three clicks from paying $12.

Now, where you might disagree with me. I’ve weighted breadth of coverage heavily, because that’s how most people use these tools. If you write in one place, in one app, with one workflow, that weighting is wrong for you and you should discount most of my case for staying. And if you think the Expert Review episode and the GPTZero purchase point at a company drifting away from the thing you bought it for, that’s a defensible read. I don’t share it, but it’s not unreasonable.
