Free Grammar and Punctuation Checker

Standard editors check for errors against a dictionary. Our service is powered by an advanced language model that understands context and meaning.

This allows it to:

• Find mistakes in complex sentences common in contracts, reports, and academic papers.
• Correctly place commas where their use depends on meaning, not just a simple rule.
• Suggest better phrasing and identify stylistic issues to make your text more readable.

Simply put: Word is a dictionary. Punctuator.org is your AI-powered writing partner.

Accuracy is our top priority. For formal and business writing (reports, memos, essays, official letters), our service is your perfect first line of defense. It will catch up to 98% of the errors and typos that you might have missed.

However, it's important to understand: for mission-critical documents where an error could have legal or financial consequences (like a signed contract or a doctoral dissertation), our service should be used as an indispensable assistant, not a substitute for final expert review. It won't replace a lawyer or a PhD advisor, but it will make their job much easier by giving them a clean, polished text to work with.

We understand the difference between a mistake and style. Our goal is to fix grammar, not kill creativity.

• For bloggers and social media managers: It won't touch your emojis 🥳, your conversational tone, or your slang if it's used correctly. But it *will* catch that embarrassing typo that can ruin the impact of even the most engaging post.
• For writers and poets: This tool is your proofreader, not your co-author. It might flag unconventional punctuation as an error. Your job is to look at the suggestion and decide if your deviation from the rules was an intentional artistic choice.

If you disagree with a correction, just ignore it. The author always has the final say.

Your privacy is fundamental. Your texts are processed automatically, and no human ever has access to them. Immediately after you check your text, all data is permanently deleted from our servers.

We do not store, analyze, or share what you check. Whether it's a business memo, a legal document, a personal email, or a new blog post—it remains yours and yours alone. You can check any document with complete peace of mind.

It's simple: your history is stored locally on your device, in your browser's memory (using a technology called localStorage). This means only you can access it. It's a secure way to combine convenience with complete privacy.

The service is completely free, with no limits on the number of daily checks. We are supported by a small amount of advertising on the page, which allows us to cover the costs of our powerful servers and make a high-quality tool accessible to everyone: from a student writing an essay to a professional drafting a business report.

To ensure fast performance for all users, there is a character limit per check (see below the input field). This allows us to guarantee high processing speeds for everyone.
