Best Grammarly Alternatives for Writing in 2025
Looking for Grammarly alternatives for proofreading and writing improvement? Here are the best options across different use cases in 2025.
Best Grammarly Alternatives for Writing in 2025
1. Claude Pro ($20/month) — Best for Rewriting
Claude Pro is not a direct Grammarly replacement — it does not live in your browser checking grammar as you type. But for editing entire documents, rewriting paragraphs, and improving prose quality, Claude Pro is significantly more capable than Grammarly’s suggestions. Best for professionals who edit in dedicated sessions rather than inline.
2. LanguageTool (Free – $4.99/month) — Best Free Grammar Check
LanguageTool is the strongest free Grammarly alternative. Open-source, supports 25+ languages (critical for non-English writers), and the browser extension works across most websites. Premium adds style improvements, rephrasing suggestions, and team features.
3. ProWritingAid ($10-30/month) — Best for Long-Form Writers
ProWritingAid is the writing tool for serious authors and long-form writers. 20+ reports including readability, sentence structure, pacing, dialogue tags, and cliche detection go far beyond Grammarly’s scope. Integrates with Word, Scrivener, and Google Docs. Better for book-length projects.
4. Hemingway Editor (Free) — Best for Clarity
Hemingway highlights complex sentences, passive voice, and adverbs with color coding. No grammar checking — purely focused on readability. Free, no account required. The best complement to any grammar tool for professionals who need clear, direct writing.
5. Microsoft Editor (Free with Microsoft 365)
Built into Word, Outlook, and Edge. If you already pay for Microsoft 365, you have a capable grammar checker included. Less sophisticated than Grammarly Premium but adequate for most professional needs.
