7 Best Grammarly Free Alternatives in 2026 (Ranked)

1. LanguageTool — best overall free alternative

LanguageTool is the closest thing to a free Grammarly, and for multilingual writers it is better than Grammarly's free plan. It is a German-built tool, running on an open-source engine that has been going since 2003, and it checks grammar, spelling, punctuation and style in more than 30 languages — English, German, French, Spanish, Portuguese, Dutch, Polish and more. The free Basic plan works on the LanguageTool website with no account and no card: paste your text, get corrections. That combination — genuinely free, no signup, many languages — is why it takes the top spot.

The free limits are small but honest, and they are the thing to understand before you build a workflow around them. LanguageTool's own comparison page lists a 2,000-character limit per text field on the free Basic plan, with 3 AI sentence rephrasings a day. Some 2026 reviews describe a higher limit, but the vendor's own page is the number to trust: a long document has to be checked in pieces. Since March 2026, the browser extension has also been Premium-only, so free users check text on the website rather than inside the apps where they write. Premium removes those limits — up to 150,000 characters per text field, unlimited AI paraphrasing, the stricter Picky Mode style rules, a personal style guide, and 20,000-plus additional checks for selected languages — at a list price of $24.90 a month, or $69.90 a year (about $5.83 a month), with the help centre quoting €59.89 a year in euros. Prices vary by country, so check the official site before paying.

The honest limits follow from that. LanguageTool is a checker, not a rewriter: it flags errors and suggests fixes, but it will not rewrite a paragraph in your voice the way QuillBot or Wordtune will, and it has no plagiarism checker. The free plan's 2,000-character cap also means a 3,000-word essay becomes a dozen pastes. But for the core job — "is this correct?" — in any of 30-plus languages, at $0, with no account, nothing else on this list comes close.

2. QuillBot — best free rewriting

QuillBot is not a Grammarly replacement on its own, and this list would be dishonest if it pretended otherwise. It does not check a whole document the way Grammarly does, and it has no tone detection or plagiarism check on the free plan. What it does — better than any other free tool here — is fix the draft you already have. Paste in a clumsy paragraph, and QuillBot rewrites it in Standard or Fluency mode, checks its grammar, and can summarise source material of up to 1,200 words so you can research faster. That is why it belongs in a Grammarly-alternative stack: Grammarly's output still needs editing, and QuillBot is the free editor.

The free limits are small but workable if you respect them. The paraphraser handles up to 125 words at a time according to QuillBot's help documentation, though some of its pricing pages now show 100 words, so expect the lower figure and split longer drafts at paragraph breaks; there is no daily cap on paraphrasing runs, only the per-run length. Free users get two of the nine paraphrase modes — Standard and Fluency — while the other modes, unlimited word counts, custom modes and the plagiarism checker sit on Premium at $19.95 per month, or $99.95 billed annually (about $8.33 per month). The free summarizer, grammar checker, citation generator and a limited AI detector round out a genuinely useful free toolkit. Use QuillBot as the second step in your workflow — check the grammar in LanguageTool, rewrite here — and its limits stop mattering very much.

The honest limits are about scope. QuillBot polishes text you bring; it cannot draft from a topic, and it will not catch every grammar error in a long document the way a full-document checker would. But as the rewriting layer on top of LanguageTool's grammar checks, it is the strongest free combination on this list — and the one most likely to make your writing actually sound better, not just more correct.

3. Hemingway Editor — best readability

Hemingway Editor does one thing, and it does it instantly: paste your text into the free web app and it highlights long sentences, very hard sentences, adverbs, passive voice and words with simpler alternatives, in colour, with a reading grade level for the whole piece. It is not a grammar checker — it will not catch a misplaced comma — and that is the point. Grammarly tells you whether your writing is correct; Hemingway tells you whether it is readable. For blog posts, marketing copy, emails and anything meant to be skimmed, readability is the harder problem, and Hemingway is the free tool that solves it.

The pricing is the simplest on this list. The web editor is free, with no account needed. The desktop app for Mac and Windows costs a one-time $19.99 — no subscription — and adds offline use plus export to Word, PDF, HTML and Markdown, with no AI features. Editor Plus is the newer subscription tier: it adds AI fixes for the issues Hemingway highlights, plus grammar and tone, from $100 a year for 5,000 AI sentences a month, with a two-week trial — though Hemingway's own billing pages have shown conflicting monthly figures, with one showing $25, so verify before paying. The classic free and desktop versions remain the core product, and for most writers they are all you need.

The honest limits are about what Hemingway is not. It does not check grammar or spelling on the free tier, it has no browser extension and no direct integration with Google Docs or Word, and it will flag long sentences that are perfectly fine in academic or technical writing — its advice is a guide, not a rule. Use it after LanguageTool and QuillBot, as the final readability pass: correct, then rewrite, then simplify. In that order, the three free tools together do most of what Grammarly Pro does.

4. ProWritingAid — best long-form editing

ProWritingAid is the manuscript tool on this list. Where Grammarly fixes sentences, ProWritingAid reads your whole document and reports on the things a grammar checker never sees: sticky sentences, overused words, sentence variation, pacing, dialogue tags, clichés and consistency. It runs more than 20 reports on your writing, and it integrates with Google Docs, Microsoft Word, Scrivener and Chrome, as well as its own Windows, Mac and web editors. For anyone revising a book, a thesis or a long report, those reports find problems that no sentence-level tool catches — which is why it is a favourite among grad students and authors.

The free plan is deliberately a demo in practice: 500 words per check, basic reports, 10 rephrases a day and 2 line-editing runs per report per day. That is enough to test whether the reports are useful on your writing, and not enough to edit a book. Premium costs $10 per month billed at $120 a year, or $30 month to month, with full access and all integrations; Premium Pro is $12 per month billed at $144 a year and adds AI Sparks and more coaching features. It also sells lifetime licenses — $399 for Premium and $699 for Premium Pro — which no other tool here offers, and which pays for itself in about three years against the annual plan. Plagiarism checking is a paid add-on, not included in Premium.

The honest limits are about fit. ProWritingAid checks English only, so multilingual writers need LanguageTool alongside it. Its free tier is the tightest on this list for long work, and its interface is heavier than Grammarly's — it is a deep desktop tool for long-form writers, so light or mobile-first writers will fight the friction. But if your writing is long enough to need structural feedback, nothing free here comes close, and the $120-a-year Premium plan undercuts Grammarly Pro while doing a job Grammarly does not attempt.

5. Wordtune — best free sentence rewriting

Wordtune works at a smaller scale than anything else on this list, and that is exactly its value. It lives in your browser as an extension, and when you highlight a sentence — in an email, a doc, a social post — it offers alternative phrasings: shorter, more formal, more casual, or simply clearer. For everyday writing, that sentence-level control is often where the work actually happens: the email is fine except for the opening line, the product description is fine except for one clunky sentence. Wordtune fixes that sentence without regenerating the whole piece, which keeps your voice intact in a way that full-draft rewriters do not — and it is the closest free match to Grammarly's full-sentence rewrite suggestions.

The free Basic plan gives you 10 rewrites and AI suggestions per day, three AI summaries per month, and unlimited spelling and grammar checks. Ten rewrites disappear quickly in a heavy writing day, so this is a daily allowance for light use, not a production quota — and Wordtune writes in English only, which matters if your audience is multilingual. Paid plans are comparatively cheap: 2026 listings put Advanced at around $7 per month on annual billing with 30 rewrites a day, and Unlimited at around $10 per month on annual billing with no caps, though monthly rates vary by listing, so check the official site. Wordtune will never replace Grammarly's full-document checking, and it should not be your only tool. As the polishing layer on top of LanguageTool, though, ten thoughtful rewrites a day is often the difference between copy that reads as corrected and copy that reads as yours.

6. Scribens — best no-account grammar check

Scribens is the quiet workhorse of this list: a free online grammar checker that asks for nothing. Open the website, paste your text, and it checks spelling, grammar, punctuation and style, with explanations for each correction and a dictionary and style suggestions alongside. There is no account to create for the basic check, which makes it the easiest tool here to try — and the only one that will take a long text without forcing you to split it into small pieces the way LanguageTool's free plan does. Independent 2026 comparisons note that its free checks handle far longer texts than LanguageTool's 2,000-character website limit, which is the practical difference that matters.

Scribens also covers more than English: it checks French as well, which is useful if you write in both languages, and it offers browser extensions and integrations for Word, Outlook and Google Docs on its paid plans. The paid Premium tier adds the integrations, a larger dictionary and more detailed style reports — check the official site for current Premium pricing, since 2026 listings quote it inconsistently. The free checker itself is the product here, not a demo of the paid one: the corrections, explanations and style suggestions are the same engine, and for a one-off check of a long document it is the fastest free answer on this list.

The honest limits are about depth and polish. Scribens is less well known than Grammarly or LanguageTool, so its suggestion quality on subtle style questions is harder to verify against independent reviews, and its interface is plainer and older-feeling than the modern tools here. It also has no paraphrasing, no summarising and no plagiarism check on the free tier. Use it for what it is: the no-account, long-text grammar check you open when LanguageTool's character cap gets in the way.

7. Trinka — best for academic writing

Trinka is the specialist on this list: an AI writing assistant built specifically for academic and technical English. Where Grammarly corrects general writing, Trinka checks whether your paper sounds like a paper — formal tone, correct technical terms, consistent use of discipline-specific vocabulary, and the formal style journals expect. It also checks for publication readiness, flagging issues that would slow down peer review, which is a job no general grammar checker attempts. For a student writing a thesis or a researcher preparing a journal submission, that focus is worth more than a general tool's broader feature list.

The free Basic plan gives you a monthly word allowance for grammar and academic-style checks — the exact allowance is not published as a single stable number, so check your account after signing up — with the deeper features, higher limits and plagiarism checks sitting on paid plans. Trinka works in the browser and as an add-in for Word, and it is designed for non-native English speakers writing in academic contexts, which is a large share of the people who search for Grammarly alternatives in the first place. Its suggestions are tuned to the conventions of research writing rather than marketing copy, so it will not tell you to shorten a methods section the way Hemingway would.

The honest limits are about scope. Trinka is an academic tool: for emails, blog posts or business writing, LanguageTool or QuillBot will serve you better, and its free allowance is small enough that a heavy writing month will push you toward a paid plan. It also has the smallest community and fewest independent reviews of any tool here, so its suggestion quality is harder to verify than LanguageTool's or QuillBot's. But if your writing is a paper, a thesis or a journal submission, Trinka is the only free tool here built for that job — and that is a real difference, not a marketing line.
