Key Takeaways

  • Grammarly Free covers spelling, basic grammar, and punctuation — but no style suggestions, no tone detection, no plagiarism check. The free tier is deliberately limited to push upgrades.
  • LanguageTool is the strongest free Grammarly alternative. It's open source, supports 30+ languages, works as a browser extension, and can be self-hosted for privacy-conscious users.
  • Google Docs includes free real-time grammar and spelling checking for any Google account user — no extension needed, no character limits, and it catches the most common writing errors.
  • Hemingway Editor is not a grammar checker. It checks readability — sentence length, passive voice, adverb density. Use it alongside a grammar tool, not instead of one.
  • Grammarly Premium genuinely earns its price for certain users: full sentence rewrites, tone adjustment, plagiarism checking against 16B+ pages, and real-time checking across every website via extension.

Grammarly Premium costs $12 per month billed monthly, or $144 per year billed annually, per Grammarly’s pricing page (2026). The free tier — which a significant portion of Grammarly’s user base uses — covers spelling, basic grammar, and punctuation. It does not include style suggestions, tone detection, plagiarism checking, sentence rewrites, or generative AI features. Those are Premium-only.

For a lot of users, that gap between free and paid is the entire reason they’re looking for alternatives. This post covers what actually works for free in 2026, what the trade-offs are, and where Grammarly Premium still earns its price.

What Grammarly Actually Does

Understanding exactly what sits behind the paywall is the first step to figuring out whether you need it.

Grammarly Free covers: spelling errors, basic grammar mistakes (subject-verb agreement, incorrect word forms, common typos), and basic punctuation issues. The browser extension applies these checks across websites and apps. This is genuinely useful for catching simple errors in emails, forms, and documents.

Grammarly Premium adds: advanced grammar suggestions (clarity, conciseness, word choice), full sentence rewrites, style suggestions (formality, tone adjustments), vocabulary enhancement, detection of unclear phrasing, plagiarism checking against 16 billion web pages, tone detection, and GrammarlyGO (generative AI for drafting, replying, and content suggestions).

Grammarly Business ($15 per member per month) adds team admin features, a shared style guide, brand tone settings, and centralized billing.

The practical difference between free and Premium is substantial. Free Grammarly is a spell-checker with some grammar awareness. Premium Grammarly is closer to a writing assistant. Whether that distinction matters depends entirely on what you write and how often.

Why People Look for Alternatives

The most common reasons are straightforward.

First, the price. $144 per year is not trivial for a writing tool, particularly for students, freelancers, or anyone who writes occasionally rather than professionally.

Second, the free tier’s limitations are felt immediately. Grammarly surfaces Premium suggestions in the sidebar but blocks them behind a paywall lock. For some users, this feels more like a sales mechanism than a product.

Third, privacy. Grammarly’s browser extension reads text from virtually every website you visit. Its privacy policy, per Grammarly’s policy page (2026), describes how it processes text to deliver its service. Users who work with sensitive documents — legal, medical, financial — often prefer a tool with different data handling, or one that can run entirely offline.

Fourth, the feature set for some users genuinely doesn’t require Premium. If you write clean prose and mostly want a safety net for typos and subject-verb errors, free tools deliver that without a subscription.

Citation capsule: Grammarly Premium costs $12/month (monthly) or $144/year (annual billing), per Grammarly’s pricing page (2026). Grammarly Business is $15 per member per month. The free tier covers spelling, basic grammar, and punctuation only. Style suggestions, tone detection, plagiarism checking, sentence rewrites, and GrammarlyGO are Premium-exclusive features.

Free Grammar-Checking Tools

LanguageTool

LanguageTool is the most capable free Grammarly alternative available. It’s open source (github.com/languagetool-org/languageTool), actively maintained, and covers grammar, spelling, and style suggestions across 30+ languages including English, German, French, Spanish, Portuguese, Dutch, and more.

The free tier, detailed on LanguageTool’s pricing page (2026), allows up to 150,000 characters per check — far more than most documents. The browser extension works in Chrome, Firefox, and Edge, checking text across websites much like Grammarly does. There’s also a web editor at languagetool.org where you can paste text directly. Microsoft Word and Google Docs integrations are available.

LanguageTool catches common grammar mistakes, punctuation errors, incorrect word forms, redundant phrases, and some style issues (wordiness, overly complex constructions). It’s more conservative than Grammarly Premium in its suggestions, which can be a feature or a limitation depending on your workflow.

The privacy case for LanguageTool is stronger than for Grammarly. For users comfortable with self-hosting, LanguageTool can be run locally via Docker or a standalone server. Text never leaves your machine. The project maintains detailed documentation for self-hosted deployments, which makes it a realistic option for organizations with data handling requirements.

LanguageTool Premium costs $4.99/month or $48/year (per their pricing page, 2026), adding picky mode, style suggestions, and higher character limits. At that price point, it’s roughly a third of Grammarly Premium’s annual cost.

LanguageTool browser extension setup

Install the LanguageTool extension from the Chrome Web Store or Firefox Add-ons. It works in Gmail, Google Docs, LinkedIn, Twitter, WordPress, and most text input fields. You do not need an account to use the basic extension. Create a free account to sync settings and access the 150,000 character limit on the web editor.

Google Docs Built-in Grammar Checker

Google Docs includes automatic grammar and spelling checking for anyone with a free Google account. No extension, no third-party service, no character limit. It catches grammar errors in real time as you type, underlines them in colored squiggles, and suggests corrections on hover or via the “Tools” menu under “Spelling and grammar.”

Per Google’s documentation on Google Docs features (2026), the grammar checking covers common errors: incorrect word usage (affect vs effect), subject-verb disagreement, missing commas in compound sentences, passive voice (highlighted, not blocked), and run-on sentences. It also suggests rewrites for certain phrasing, though less aggressively than Grammarly Premium.

For users who already write primarily in Google Docs, this is the simplest path. It’s genuinely free, it requires no installation, and it works offline in certain modes once the document has loaded. The main limitation is that it only works within Google Docs — it doesn’t extend to your email client, browser forms, or other apps.

Microsoft Editor

Microsoft Editor is Microsoft’s grammar and writing assistant, available as a browser extension for Chrome and Edge, and built into Microsoft 365 applications including Word and Outlook. The extension works similarly to Grammarly: it reads text across websites and surfaces corrections in a sidebar.

The free tier of Microsoft Editor, per Microsoft’s Editor product page (2026), covers spelling and basic grammar in the Edge browser and in any browser with the extension installed. Advanced style suggestions — conciseness, formality, inclusive language, clarity — require a Microsoft 365 subscription at $6.99/month for Personal.

If you’re already paying for Microsoft 365, you’re getting Grammarly-comparable style suggestions at no additional cost via Microsoft Editor. For users on the free tier of Microsoft’s ecosystem, Editor’s grammar coverage is solid for catching common errors, but thinner than LanguageTool’s free feature set on style suggestions.

Microsoft Editor in Edge vs other browsers

In Microsoft Edge, the built-in Editor integration is more tightly connected to Microsoft’s services and checks spelling and grammar natively in any text field without a separate extension install. In Chrome or Firefox, the Editor browser extension delivers the same free grammar checks but requires manual installation from the respective extension stores.

Hemingway Editor

Hemingway Editor (hemingwayapp.com) is worth covering honestly because it’s frequently recommended alongside grammar checkers — and it doesn’t check grammar. It checks readability.

Hemingway highlights sentences that are hard to read (too long or structurally complex), sentences in passive voice, adverbs that could be removed, phrases with simpler alternatives, and overall reading grade level. It color-codes these issues and gives a readability score. It does not catch spelling mistakes, grammatical errors, incorrect word forms, or punctuation issues.

This distinction matters. Hemingway is useful for writers who want to tighten their prose and reduce complexity. It’s not a proofreading tool. Used together with LanguageTool or Google Docs’ grammar checker, it covers a different and complementary dimension of writing quality.

The web version at hemingwayapp.com is free to use with no account required, no character limit, and no file upload. You paste text directly into the editor. The desktop app for Windows and macOS is a one-time purchase of $19.99, per Hemingway’s product page (2026), and adds import/export features including direct publishing to WordPress and Medium.

Hemingway is a readability tool, not a grammar checker

Hemingway will not catch “your” vs “you’re,” subject-verb disagreement, or misplaced commas. If you’re using it as a Grammarly replacement, you’ll still need a separate grammar checker. Use Hemingway after you’ve already run a grammar pass — it works best as the final step to simplify dense writing, not as the first line of proofreading.

ProWritingAid

ProWritingAid is a writing assistant that combines grammar, style, readability, and detailed reports on things like cliché usage, sentence length variety, pacing, and overused words. It’s more comprehensive than Grammarly’s style suggestions in some dimensions, particularly for long-form writing like novels, academic papers, and technical documentation.

The free tier, per ProWritingAid’s pricing page (2026), limits checks to 500 words per document and restricts the browser extension to 2,000 characters per check. This is significantly more constrained than LanguageTool’s free offering, which makes ProWritingAid’s free tier a “try before you buy” rather than a working free tool for everyday use.

ProWritingAid Premium starts at $20/month or $79/year (per their pricing page, 2026). For long-form writers who want more detailed reports than Grammarly provides, it’s worth evaluating — but its free tier is not a practical Grammarly replacement at those limits.

Citation capsule: LanguageTool’s free tier supports 150,000 characters per check with grammar and style suggestions across 30+ languages, per LanguageTool’s pricing page (2026). ProWritingAid’s free tier limits checks to 500 words and 2,000 characters in the browser extension. Microsoft Editor’s free tier covers spelling and basic grammar; style suggestions require a Microsoft 365 subscription at $6.99/month. Hemingway Editor is free to use in browser for readability analysis, not grammar checking.

kordu.tools Text Utilities

kordu.tools does not have a grammar checker. Being direct about that matters. What it does have are text utilities that fit into a broader writing workflow — distinct from proofreading but genuinely useful at different stages.

Word Counter

Count words, characters, sentences, and paragraphs with reading time, speaking time, and keyword density.

Try it free

Word counter gives you word count, character count, sentence count, paragraph count, and reading time. Useful when you’re writing to a brief, trimming content to a target length, or need to check reading time before publishing.

AI Text Summarizer

Summarize articles, essays, and documents with AI. Choose length, get bullet points, see word-count reduction. Runs on-device.

Try it free

Text summarizer condenses long text into key points. Useful for checking whether your own writing communicates its main ideas clearly — if the summary misses your point, so might a skimming reader.

Sentiment Analyzer

Analyze text sentiment instantly — see positive, negative, and neutral scores with a per-word breakdown. No AI model required.

Try it free

Sentiment analyzer reads the emotional tone of a piece of text — positive, negative, neutral. This is a different axis from grammar or readability, useful for marketing copy, customer-facing emails, or content where tone management matters.

Case Converter

Convert text between UPPERCASE, lowercase, Title Case, camelCase, snake_case, kebab-case, and more — instantly.

Try it free

Case converter handles capitalization transformations: title case, sentence case, UPPERCASE, lowercase, camelCase, and more. Not a writing quality tool, but a practical time-saver when copying content between systems with different capitalization requirements.

These tools do not replace grammar checking. Use them alongside LanguageTool, Google Docs’ built-in checker, or Microsoft Editor — not instead of them.

Built-in and Offline Grammar Checking

LibreOffice Writer

LibreOffice Writer, the free and open-source word processor from The Document Foundation (current version 24.8 as of 2026), includes built-in spell checking via Hunspell and supports grammar checking via a LanguageTool integration.

Out of the box, LibreOffice Writer checks spelling and highlights errors in real time. Grammar checking requires installing the LanguageTool extension from the LibreOffice Extension Center and configuring it to connect to LanguageTool’s remote API or a locally hosted instance. Once configured, you get the same LanguageTool grammar coverage — 30+ languages, detailed suggestions — inside a full offline document editor.

For users who want a completely offline writing environment with grammar checking, LibreOffice Writer plus a self-hosted LanguageTool instance is the most privacy-preserving setup available. No text leaves your machine.

macOS and Windows Built-in Spell Checking

Both macOS and Windows include system-level spell checking that applies across most native apps.

On macOS, spell checking is active by default in Mail, Pages, Notes, and any app using native text input components. macOS also includes a grammar checker under Edit > Spelling and Grammar > Check Grammar with Spelling. It catches basic errors but is significantly less thorough than dedicated tools.

On Windows, Windows 11’s built-in spell checker works across apps that use the Windows spell checking API. The Microsoft SwiftKey-based suggestions in Windows 11’s touch keyboard include some grammar awareness, but system-level grammar checking is minimal compared to a browser extension.

These built-ins are the zero-effort baseline — they catch obvious typos — but they’re not a replacement for a dedicated tool if writing quality matters.

Set your language correctly in spell checkers

Most built-in spell checkers default to American English. If you write in British, Australian, or Canadian English, check your system and application language settings. Using the wrong dialect variant causes false positives — “colour” flagged as an error when it’s correct — which trains users to ignore legitimate corrections.

Citation capsule: LanguageTool is the only free tier option in this comparison that supports 30+ languages, offers self-hosting for privacy, and provides style suggestions without a paid plan. Grammarly Free is English-centric; its advanced multilingual support is limited to Premium. Google Docs grammar checking covers many languages and requires no additional installation for existing Google Docs users, per Google’s documentation (2026).

Which Alternative Is Right for You?

The right tool depends on what you write, where you write it, and how often.

Casual writers and students

You write emails, Google Docs, the occasional report. Your main concern is typos and obvious grammar errors before hitting send. The combination of Google Docs’ built-in checker for documents and LanguageTool’s browser extension for everything else covers most of what you need, for free. You do not need Grammarly.

Non-English writers

LanguageTool’s 30+ language support makes it the clear recommendation. Grammarly’s core strengths are in English. If you write primarily in German, French, Spanish, Portuguese, or another supported language, LanguageTool’s grammar checking in your language is stronger than Grammarly’s free tier in any language.

Privacy-conscious users or organizations

LanguageTool self-hosted, combined with LibreOffice Writer, is the only configuration in this comparison where text never leaves your machine. For legal, medical, or financial writing where you can’t upload documents to third-party cloud services, this is the practical path.

Long-form writers (novelists, academics, technical writers)

Start with LanguageTool for grammar. Add Hemingway Editor as a readability pass after you’ve drafted. ProWritingAid’s paid tier adds deeper analysis of long-form issues (pacing, sentence variety, cliché density) if you want that level of detail. Google Docs’ suggestion mode works well for collaborative editing on documents.

Professional writers and editors

If you write for clients, edit others’ work, or produce high-volume content where quality errors have real consequences, LanguageTool Premium at $48/year is the most cost-effective paid option. It’s a third of Grammarly Premium’s annual price with comparable grammar coverage. The main thing LanguageTool Premium lacks versus Grammarly Premium is the plagiarism checker — if that’s a requirement, Grammarly’s pricing becomes more defensible.

What You Actually Need Grammarly For

Being honest about where Grammarly Premium genuinely earns its price is more useful than dismissing it.

Full sentence rewrites. Grammarly Premium doesn’t just flag a problematic sentence — it rewrites it. For users who know something reads awkwardly but aren’t sure how to fix it, this is a meaningfully different capability than a tool that highlights the issue without offering a complete alternative.

Tone detection and adjustment. Grammarly identifies whether writing reads as formal, casual, direct, confident, or diplomatic, and suggests adjustments to match your intended tone. This works across emails, documents, and browser text fields. LanguageTool doesn’t offer this.

Plagiarism detection. The Premium plagiarism checker compares your text against Grammarly’s index of 16 billion web pages, per Grammarly’s feature documentation (2026). For academic writing, student submissions, or content marketing where duplicate content is a concern, this is a standalone valuable feature.

Enterprise style guides. Grammarly Business lets organizations define a custom style guide — brand terminology, preferred phrasings, words to avoid — and enforce it across all users via the extension. No free tool offers this.

Real-time checking across all websites. Grammarly’s extension works in essentially every text field: Gmail, Slack, Twitter, LinkedIn, Notion, your company’s internal tools. LanguageTool’s extension covers many of these too, but Grammarly’s coverage and integration depth is broader and more polished.

GrammarlyGO generative AI. The AI drafting, email reply generation, and content suggestions built into Grammarly Premium represent a category that free tools don’t touch. If you want AI writing assistance as a single integrated tool alongside grammar checking, Grammarly Premium is currently ahead.

Grammarly's 7-day free trial of Premium

Grammarly offers a free trial of Premium. If you’re genuinely on the fence, run the trial for a week on your actual writing. You’ll know within a few days whether the Premium features change how you work or whether LanguageTool plus Google Docs handles what you actually need.

Frequently Asked Questions

Is there a completely free grammar checker?

Yes. LanguageTool’s free tier is the most capable completely free grammar checker available in 2026. It covers grammar, spelling, and some style suggestions across 30+ languages with a 150,000 character limit per check. Google Docs also includes built-in grammar checking for free with a Google account. Both are genuinely usable tools, not crippled demos.

What is the best free alternative to Grammarly?

LanguageTool. It’s open source, supports the broadest range of languages, works as a browser extension across websites, and delivers grammar and style suggestions without a paywall. For users who work primarily in Google Docs, Google’s built-in grammar checker combined with LanguageTool’s extension is a strong no-cost setup.

Is LanguageTool as good as Grammarly?

For grammar checking specifically, LanguageTool free is competitive with Grammarly Premium. Per comparative analyses from sources including PCMag’s grammar checker roundup (2025), LanguageTool catches a high percentage of grammar errors and outperforms Grammarly in multilingual support.

Where LanguageTool trails Grammarly Premium: full sentence rewrites, tone detection and adjustment, the plagiarism checker, enterprise style guide enforcement, and the generative AI drafting features. For a user who primarily wants grammar and spelling errors caught, LanguageTool free performs at a comparable level. For a user who wants the full writing assistant experience, Grammarly Premium is more complete.

Does Google Docs check grammar for free?

Yes. Google Docs includes automatic grammar and spelling checking for all Google account users at no cost, with no extension required. It checks in real time as you type. The quality of its grammar checking covers common errors effectively. It doesn’t offer the style suggestions, tone analysis, or plagiarism checking that Grammarly Premium provides, but for catching grammatical errors in Google Docs, it works without paying for anything.

Is Grammarly worth paying for?

For most casual writers who write primarily in a few apps: no. LanguageTool free plus Google Docs’ built-in checker covers the core use case of catching grammar and spelling errors without a subscription.

For professional writers, content marketers, editors, or anyone writing high-stakes communications at volume: possibly yes. The sentence rewrites, tone adjustment, plagiarism detection, and all-sites extension coverage represent a meaningful quality upgrade over free tools. At $144/year, the question is whether the time saved and errors prevented justify the cost for your specific output level.

Conclusion

Grammarly built a strong product. It’s also built around a monetization model that gates its most useful features behind a $144/year subscription and surfaces them constantly on the free tier as upgrade prompts. For most users, the free alternatives in 2026 are good enough to avoid that entirely.

LanguageTool is the recommendation: open source, 30+ languages, self-hostable, free tier that actually works. Google Docs’ built-in grammar checker handles document writing for anyone already in that ecosystem. Add Hemingway Editor as a readability pass on important writing, and you have a complete free workflow.

The cases where Grammarly Premium genuinely pulls ahead — sentence rewrites, tone detection across all apps, plagiarism checking, enterprise style guides — are real. If those features are part of your actual workflow, the price is defensible. If they’re not, LanguageTool costs nothing and covers what matters.
