1. Grammarly Free — Start Here
Before looking elsewhere, Grammarly’s own free tier catches most grammar and spelling errors across every text field in your browser. No word limits. 100 AI prompts per month for basic rewrites.
What’s missing vs Premium: No full-sentence rewrites, no tone adjustment, no plagiarism detection, no vocabulary enhancement. But for catching errors? Free is 80% of the value.
2. LanguageTool — Best for Non-English Writers
LanguageTool supports 30+ languages. The free tier checks up to 10,000 characters per text with grammar, spelling, and style suggestions. Browser extension works in most text fields.
Why it wins: If you write in German, Spanish, French, or any non-English language, LanguageTool is significantly better than Grammarly, which primarily supports English.
Paid upgrade: $7/month (annual) for longer text checks and advanced style suggestions. Cheaper than Grammarly Pro.
3. ProWritingAid Free — Deepest Analysis
ProWritingAid’s free tier limits you to 500 words per check, but the depth of analysis is unmatched: 20+ reports on style, readability, sentence variation, overused words, pacing, and more.
Best for: Writers who want to understand their writing patterns, not just fix errors. The reports teach you to write better over time.
Workaround: Check your document in 500-word chunks. Tedious but functional for longer pieces.
4. Hemingway Editor — Best for Clarity
Hemingway doesn’t check grammar. It checks readability. Paste your text and it highlights hard-to-read sentences, passive voice, adverbs, and complex words. The web version is free forever.
Best for: Making dense, academic, or corporate writing more readable. Pair it with Grammarly Free: Grammarly catches errors, Hemingway improves clarity.
5. ChatGPT or Claude Free — AI-Powered Editing
Paste your text into ChatGPT or Claude and ask it to “edit this for clarity and tone” or “rewrite this more concisely.” Both free tiers handle this well.
Why it works: More flexible than any grammar tool. You can ask for specific tone (formal, casual, persuasive), restructure paragraphs, or get alternative phrasings. No word limits per check.
Limitation: Doesn’t work inline in your browser like Grammarly does. You need to copy-paste.
Best free combo: Grammarly Free (real-time error catching) + Hemingway (readability) + ChatGPT/Claude (AI rewriting). Together they cover 90% of what Grammarly Pro does, for $0.
Non-English writers: LanguageTool. No contest.
Fiction/long-form writers: ProWritingAid Free for deep analysis, despite the 500-word limit.
Still worth paying for Grammarly Pro? Only if you write professionally every day and value the seamless, always-on experience. The free alternatives require more effort but save $144/year.
