AI Grammar & Style Checker

Yes! Our AI grammar checker is completely free to use with no signup required. You can check up to 5,000 characters at a time, which covers most documents, emails, and essays.

Our grammar checker uses advanced AI models (GPT-4o-mini) to detect grammar, spelling, style, and clarity issues with high accuracy. However, AI is not perfect. We recommend reviewing all suggestions and using your judgment, especially for context-specific writing.

Our tool detects four main types of issues:

• Grammar Errors: Subject-verb agreement, tense consistency, sentence fragments, etc.
• Spelling Errors: Misspelled words and typos
• Style Suggestions: Passive voice, wordiness, repetition, and tone improvements
• Clarity Improvements: Confusing phrasing, ambiguous references, and readability enhancements

Yes, but always check your institution's policies on AI tool usage. This tool is designed to help you identify and fix errors in your own writing - not to generate content for you. Think of it as a writing assistant that highlights potential issues you should review.

No. Your privacy is our priority. We never store, log, or share your text. Processing happens via secure AI APIs, and the text is immediately discarded after analysis. Your history is saved locally in your browser only (using IndexedDB) and never sent to our servers.

Our tool is completely free, requires no account signup, and respects your privacy by never storing your data. We use advanced AI models to provide grammar checking capabilities similar to premium tools, but with a focus on simplicity and privacy. It's perfect for quick checks without the need for subscriptions or extensions.

Currently, our grammar checker is optimized for English text. The AI model can handle various English dialects (American, British, Australian, etc.) and will provide appropriate suggestions based on the context of your writing.

You can check one document at a time (up to 5,000 characters). For longer documents, we recommend breaking them into sections and checking each part separately. Your recent checks are saved in your browser's history, making it easy to revisit and compare previous analyses.
