The Reddit thread that started it is four years old and still gets comments: "Grammarly alternatives? The yearly subscription has gone up so significantly (+66%!)..." The price is only half the complaint. The other half is that after years of updates, Grammarly still corrects conservatively, still nags you toward its own voice, and still sends every sentence you write to someone else's servers.
This guide ranks nine alternatives by the thing listicles usually ignore: what you actually write. A tool that's perfect for a novelist is wrong for a support agent, and vice versa. A disclosure up front: we build AmberPen, a proofreading API for developers, so we spend our working lives measuring grammar checkers. We don't sell a consumer app, we have no affiliate links in this article, and where another tool wins, we say so.

If you're paying for Grammarly Premium and want the closest like-for-like swap at a lower price, start with LanguageTool. If you write books, jump to ProWritingAid. If you want out of the cloud entirely, Hemingway and Harper are the two honest options. The rest of this article is the evidence.
1. LanguageTool — the best all-around Grammarly alternative
LanguageTool is the answer in most "alternative to Grammarly" threads for a reason: it does the same job (browser extension, desktop apps, Google Docs and Word add-ins, as-you-type corrections) at less than half the price, and it catches a comparable share of everyday errors.
Two things separate it from Grammarly. The first is multilingual depth: over 30 languages with real grammar rules, not just English with translation bolted on — if you write in German, French, Spanish, or Portuguese alongside English, nothing else on this list comes close. The second is privacy posture: it's EU-hosted (Germany), doesn't train on your text, and — unusually — the core rule engine is open source, so you can self-host it entirely if you want Grammarly-style checking with zero data leaving your network.
Where it loses to Grammarly: the tone-rewrite layer. LanguageTool suggests corrections and some rephrasing, but it won't rewrite your email to sound more confident, and its fluency suggestions are less polished. If Grammarly's sentence rewrites are the feature you actually use, LanguageTool will feel like a downgrade.
Verdict: the default recommendation for anyone whose main complaint is price. Free tier is genuinely usable; Premium (~$5/mo on annual billing) undercuts Grammarly by more than half.
2. ProWritingAid — for novelists, academics, and anyone writing long
ProWritingAid is less a Grammarly competitor than a different category that happens to overlap. Grammarly works sentence by sentence; ProWritingAid runs twenty-plus reports over a whole document — pacing, dialogue tags, repeated words, sentence-length variety, readability grade, sticky sentences, clichés. Run the pacing report over a 90,000-word manuscript and you can see the sagging middle in one chart. Grammarly has nothing comparable.
It also corrects more aggressively and explains itself more — every flag comes with a rule name and a teaching blurb, which makes it the better tool if you want to become a better writer rather than just ship cleaner text. The cost of that aggression is noise: a meaningful share of its style suggestions are judgment calls you'll dismiss.
The pricing structure is the hidden win. Beyond the usual subscription ($10/mo annual), ProWritingAid sells a lifetime license ($399, frequently discounted) — if you plan to use a writing tool for more than three years, the math beats every subscription on this list.
Where it loses: no mobile keyboard, the free tier's 500-word cap makes it a demo rather than a tool, and the browser extension historically struggles with Google Docs performance on long documents. We compared it head-to-head with Grammarly in Grammarly vs ProWritingAid if you want the full breakdown.
Verdict: if you write manuscripts, theses, or reports, this is the upgrade, not the alternative.
3. Hemingway Editor — the anti-Grammarly
Hemingway barely checks grammar at all. It highlights long sentences, passive voice, adverbs, and needlessly complex words, and gives you a readability grade. That's the whole product — and for a certain kind of writer, it's more useful than any grammar checker, because their problem was never commas, it was flab.
Two more things make it a genuine Grammarly alternative rather than a toy: it runs locally (paste text into the web app and nothing leaves your browser; the desktop app is a $10 one-time purchase), and it costs less than a single month of Grammarly Premium.
Where it loses: it won't catch your typos, agreement errors, or misused homophones. Most people pair it with something else — Hemingway for style, a grammar checker underneath.
Verdict: not a replacement, a complement. Buy the desktop app once, keep it forever.
4. QuillBot — for paraphrasing and ESL fluency
QuillBot built its name on the paraphrasing tool and added grammar checking, summarizing, and citation features around it. Its grammar checker is competent but not the reason to switch — the reason is the rewrite engine, which is stronger than Grammarly's for rephrasing awkward sentences, especially for non-native speakers who know what they mean but can't find the natural English shape for it.
Where it loses: the free tier is thin, the grammar engine flags less than Grammarly's (let alone ProWritingAid's), and the product increasingly positions itself as an AI writing suite, which is either a plus or a red flag depending on why you're leaving Grammarly.
Verdict: the right pick if rewriting, not correcting, is the job.
5. Microsoft Editor — the free one you already have
If you have a Microsoft 365 subscription — or just use Edge — you already have Microsoft Editor. It checks spelling, grammar, clarity, conciseness, and formality across Word, Outlook, and (via the browser extension) the whole web. The corrections are solid for everyday business writing, and the price is unbeatable: it's bundled.
Where it loses: the suggestions are shallower than Grammarly's premium tier, the style feedback is sparse, and the privacy story is "governed by Microsoft's data policies," which is fine for most people and disqualifying for some. It also has no meaningful presence on Google Docs, which rules it out for a lot of teams.
Verdict: before paying for anything, spend a week with the tool already in your taskbar. For email-and-documents work, it may be enough.
6. Google Docs' built-in checker — the minimum viable option
Google Docs ships with spelling and grammar suggestions that quietly improved from rules to machine learning over the past few years. It catches the common stuff — agreement, confusables, tense drift — with almost no setup and no cost.
Where it loses: it catches less than everything else on this list, there's no style feedback, no reports, no explanations, and your text is processed under Google's standard terms. If you're writing in Google Docs anyway and your needs are modest, it's the zero-effort option; if you were ever paying Grammarly for its deeper suggestions, you'll notice the gap immediately.
Verdict: the floor. Fine for casual writing, not a Grammarly replacement for anyone who relied on Premium.
7. Scribbr — for academic papers specifically
Scribbr's AI proofreader targets academic text: it scans for the errors that matter in papers (academic style, hedging, citation-adjacent issues) and returns corrections with tracked-changes-style review. It's built by a company whose main business is human proofreading and plagiarism checking for theses, and the tool inherits that focus.
Where it loses: it's document-upload based, not as-you-type; there's no browser extension worth mentioning; and it's priced per document or as part of a broader academic service, which makes no sense for email or blogging. This is a specialist, not a generalist.
Verdict: if your "Grammarly use case" is actually your dissertation, start here instead.
8. Harper — the open-source, private, offline option
Harper is the outlier: a free, open-source grammar checker that runs entirely on your machine — as a command-line tool, a language server for your editor (VS Code, Neovim, Obsidian), or a library. No account, no cloud, no telemetry, no subscription. Because it's in-process, it's also instant: single-digit-millisecond checks while you type.
The trade-off is capability. Harper is rule-based, not neural, so its corrections are narrower than Grammarly's — it excels at the mechanical layer (typos, agreement, repeated words, common confusables) and doesn't attempt tone rewrites or fluency suggestions. For developers and privacy-sensitive writers who were leaving Grammarly over data practices rather than price, that trade is often exactly what they want.
Verdict: the only option on this list where "Grammarly alternative" and "no cloud, ever" are both literally true. If you live in a code editor, it's not even close.
9. AmberPen — if what you actually need is an API
Here's the case none of the consumer tools cover: you're not a writer looking for a checker — you're building a product that needs proofreading inside it. Your own editor, your own UI, your own users. Grammarly can't do this at all (its developer APIs return scores, not corrections — we documented that in Does Grammarly Have an API?), and neither can ProWritingAid, Hemingway, or QuillBot. Their products are the interface; the interface is not for sale.
AmberPen is a neural proofreading API: you send text, you get back structured edits — exact offsets, replacements, and explanations — and render them however you want in your own product. It streams corrections as the model generates them (which is what makes as-you-type checking feel instant), supports custom dictionaries per request so your product names never get "corrected," and doesn't train on your text.
Pricing is usage-based: €5/month for the Starter plan (500K characters included, then €9 per million) or €49/month for Pro (9M characters included, then €6 per million). For scale context: 500K characters is roughly a 70,000-word novel, or about 25,000 typical emails. There's a free test key on the homepage — no card, paste text, see the corrections.
Verdict: if you searched "Grammarly alternative" because you want to build rather than write, this is the section you were looking for. Our best grammar checker APIs roundup compares AmberPen against Sapling, LanguageTool, GrammarBot, and others if you want the developer-grade version of this list.
How to choose, in one decision tree
- Leaving Grammarly over price, want the same experience? → LanguageTool.
- Writing a book, thesis, or long reports? → ProWritingAid.
- Your problem is style, not grammar? → Hemingway.
- You mostly need paraphrasing / ESL fluency help? → QuillBot.
- You write academic papers? → Scribbr.
- You want free and already pay for Microsoft 365? → Microsoft Editor.
- You want free and live in Google Docs? → Google's built-in checker.
- You want private, offline, open source? → Harper (or self-hosted LanguageTool).
- You're building a product that needs corrections in it? → AmberPen.
One honest closing note: no tool on this list matches Grammarly on surface area. The browser extension, the desktop apps, the mobile keyboards, the Office integration, the tone rewrites — Grammarly's coverage of everywhere-you-write is still the widest, and the polish of its suggestions is still the benchmark everyone else is compared against (including here). If none of the specific frustrations above are yours, staying is a defensible choice. But if price, privacy, or the conservative corrections pushed you to search for an alternative, one of the nine above is almost certainly a better fit — and most of them cost less.
