Grammar correction and document analysis are separate jobs
Start with LanguageTool for browser-based grammar and style checks, especially if you write in more than one language. Add ProWritingAid when its 500-word free window and report limits suit the draft. Grammarly Pro is easier to justify when full-sentence rewrites, tone adjustment, and plagiarism checking must live in one interface; basic correction does not require that bundle.
Daily caps and editing depth drive the switch
Grammarly Free covers spelling and grammar correction, displays writing tone, and includes a limited monthly allowance for generated text. Grammarly Pro adds full-sentence rewrites, tone adjustment, fluency suggestions, plagiarism checks, and a larger generation allowance. Grammarly lists the current split on its plans page.
The paid plan has to save enough editing work to justify a recurring subscription. Occasional letters and emails rarely need the whole bundle, while frequent rewrites, plagiarism checks, or shared writing standards can make the paid features more relevant.
Most users need grammar checks, clarity flags, and word-choice suggestions. The free tools below cover those jobs, but some require more setup or offer fewer browser integrations than Grammarly.
Four free Grammarly alternatives
1. LanguageTool: best for multilingual writers and everyday grammar checking
LanguageTool is an open-source grammar and spell checker that supports over 30 languages, available as a browser extension, desktop app, and web editor.
What you can use for free:
- Grammar, spelling, and punctuation checking in 30+ languages
- Browser extension for Chrome, Firefox, Edge, and Safari
- Integration with Google Docs, Gmail, and most web text editors
- A free text-length allowance for grammar checks, with the exact cap varying by product surface and current plan terms
- Basic style suggestions
The practical limit:
- Advanced phrasing suggestions and synonym recommendations (Premium)
- Longer text checks without splitting usually require Premium
- AI-powered paraphrasing tool
- Personal dictionary on some platforms requires an account
LanguageTool fits multilingual writing and everyday spelling or grammar checks within its free limits.
Where it makes the biggest difference: LanguageTool’s browser extension works in Gmail, Google Docs, WordPress, Notion, and other web editors. Its clearer advantage is multilingual support: the same extension checks German, Spanish, French, Portuguese, and English. Choose it when your writing crosses languages; that is a more concrete reason than simply wanting a second English grammar checker.
Who might find the free tier limiting: LanguageTool’s free text-length allowance is not a problem for email and social media, but very long documents may need to be checked in sections. For a 5,000-word article, that can mean splitting the text multiple times, which adds a small but real extra step. Writers who regularly edit long pieces in a single session should check LanguageTool’s current free limit before relying on it as their only editor.
2. ProWritingAid: best for long-form writers who want structural feedback
ProWritingAid is a writing analysis tool that checks grammar, style, readability, and sentence structure. The free tier covers its core editing workflow.
What you can do for free:
- Grammar and spelling checks
- Style and readability reports
- Up to 500 words checked per session on the free web editor
- Browser extension with basic checks
- Integration with Google Docs and Microsoft Word (with limitations on free)
Where the paywall sits:
- Unlimited document length (free caps at 500 words per check)
- Unlimited runs of its 25-plus writing reports
- Advanced style suggestions and broader integrations
- Plagiarism checker
ProWritingAid fits longer drafts that need reports on sentence variety, pacing, and repeated words, within its word and report caps.
Where it helps most: ProWritingAid includes reports for repeated sentence openings, passive voice, readability, and overused words. Free users can run each report twice a day on up to 500 words at a time; paid plans remove those two boundaries. The current plan comparison lists the report and rephrase allowances.
3. Hemingway Editor: best for improving readability and cutting clutter
Hemingway Editor is a web-based editor that highlights hard-to-read sentences, passive voice, adverbs, and overly complex phrasing, with a simple readability grade.
What you can do for free:
- Full readability analysis in the browser: completely free
- Color-coded highlights for different types of issues
- Readability grade score
- Word and sentence count
- No account or login required
Where the paywall sits:
- No grammar or spelling checking
- The desktop app (which adds Word and Google Docs export) requires a one-time purchase
- No browser extension: you must paste text into the Hemingway web editor
Hemingway fits a final readability pass on prose that needs shorter sentences and less clutter. It does not replace a grammar checker.
Where it helps most: Hemingway Editor focuses on readability rather than grammar or word choice. Its color-coded interface marks complex words, very hard sentences, hard sentences, and adverbs. The highlights show where to review a draft, but the writer still has to decide whether each suggested change improves the meaning. Pair it with LanguageTool when you also need spelling and grammar checks.
4. Google Docs built-in tools: best for writers already using Google Docs
Google Docs built-in tools is the grammar, spelling, and smart compose features built into Google Docs, available to anyone with a free Google account.
What you can do for free:
- Real-time spelling and grammar checking
- Smart Compose: predictive text suggestions as you type
- Smart Reply suggestions in Gmail
- Basic style suggestions in newer Docs versions
- Works across all devices with no additional setup
Where the paywall sits:
- No dedicated browser extension for other platforms
- Style analysis is basic compared to LanguageTool or ProWritingAid
- No readability scoring
- Suggestions are less detailed than dedicated writing tools
Google Docs fits writers who want its built-in spelling and grammar checks without installing another extension.
Where it helps most: Google Docs includes real-time spelling and grammar checks plus Smart Compose. A Docs-first writer may not need another extension for ordinary emails and business documents, and using the built-in checks requires no additional account. If you are considering leaving Microsoft Word, see our free Microsoft Office alternatives guide.
Compare daily limits and editing depth
| Tool | Free word limit | Languages | Style suggestions | Best for |
|---|---|---|---|---|
| LanguageTool | Text-length cap varies | 30+ | ✅ Basic on free | Multilingual writers, everyday grammar |
| ProWritingAid | 500 words per session | English (primarily) | ✅ Deep on free | Long-form writers, structural editing |
| Hemingway Editor | Unlimited (web) | English | ⚠️ Readability only | Cutting clutter, improving clarity |
| Google Docs | Unlimited | Multiple | ⚠️ Basic | Writers already using Google Docs |
| Grammarly free | Unlimited | English | ⚠️ Limited on free | Quick grammar checks, familiar UX |
Which tool for which writing task
The free tools above are not competing replacements: they work better in combination than any single one does alone. A practical stack for most writers:
- LanguageTool as the always-on browser extension: catches grammar and spelling across every text field, every day, automatically.
- Hemingway Editor for a final readability review: paste in the finished draft and inspect the red and yellow highlights before publishing.
- ProWritingAid for essays, articles, and reports where structure and sentence variety matter as much as grammar.
For email writing specifically: Google Docs’ Smart Compose or LanguageTool’s extension is sufficient. Running email drafts through ProWritingAid’s 500-word limit adds work without much benefit for a message that will be read once.
For academic writing: ProWritingAid’s structural reports (passive voice, sentence variety, readability per paragraph) are more useful than grammar checking alone. The 500-word session cap on the free plan is a genuine inconvenience for long papers, but editing in sections, introduction, body, conclusion, makes it workable without a subscription.
For multilingual writers: LanguageTool supports more than 30 languages. Hemingway Editor and ProWritingAid focus on English, while Google Docs supports spelling and grammar features for selected languages.
When Grammarly Pro makes sense
Grammarly Pro makes sense when full-sentence rewrites, tone adjustment, fluency suggestions, and plagiarism checks need to stay inside the same editor. Grammarly Free already displays writing tone, so tone visibility alone is not a reason to upgrade.
The paid rewrite tools may help someone who frequently reworks phrasing in English. Compare that feature with the manual editing time it replaces rather than assuming every draft needs it.
The plagiarism checker bundled with Pro is relevant to students, researchers, and editors who are permitted to upload the document to the service. Check institutional rules and Grammarly’s data controls before sending unpublished or sensitive material.
LanguageTool first, then specialist checks
Use LanguageTool for multilingual correction, ProWritingAid for report-based review in 500-word sections, and Hemingway Editor for readability highlights. Pay for Grammarly Pro when full-sentence rewrites, tone adjustment, and plagiarism checking need to stay in one interface.
