Grammarly's premium plan costs $12–$30 per month — which adds up fast. The good news? For most everyday writing needs, free alternatives work just as well. Here are the five best free grammar and writing tools available in 2025.
1. AILabForce Grammar Checker (Free)
Our built-in grammar checker catches the most common mistakes: confused words (their/there/they're), double spaces, passive voice overuse, redundant phrases, and more. It works entirely in your browser with no data sent to any server. Perfect for quick checks on short documents.
2. LanguageTool (Free Tier)
LanguageTool is one of the most powerful free grammar tools available. The free version checks grammar, spelling, and style in over 30 languages. It also offers browser extensions for Chrome and Firefox, making it easy to check text anywhere you write online.
3. Hemingway Editor (Free Web Version)
The Hemingway Editor focuses on readability rather than grammar. It highlights long, complex sentences, passive voice, and adverbs — helping you write more clearly and confidently. The web version at hemingwayapp.com is free to use.
4. ProWritingAid (Free Tier)
ProWritingAid offers a surprisingly powerful free tier that includes basic grammar and spelling checks, a readability analysis, and a word explorer. The free version has usage limits, but for occasional editing it is more than sufficient.
5. Google Docs Built-in Spell Check
Often overlooked, Google Docs has significantly improved its grammar checking in recent years. It catches comma usage errors, subject-verb agreement problems, and even some style suggestions — all for free as part of Google Workspace.
