Frequently Asked Questions
Our grammar checker achieves over 95% accuracy using advanced AI models trained on millions of professionally edited documents. It categorizes errors into 6 specific types (Grammar, Spelling, Punctuation, Clarity, Formality, Conciseness) and provides detailed explanations for each correction. Unlike basic tools, it understands context and meaning to detect complex errors.
The tool detects and categorizes 6 types of errors: Grammar (subject-verb agreement, tense errors), Spelling (misspellings, typos), Punctuation (missing commas, apostrophes), Clarity (unclear phrasing), Formality (inappropriate tone), and Conciseness (wordiness). Each error includes the original text, corrected version, and explanation.
Our system uses transformer-based neural networks that analyze entire sentences for context. This enables detection of complex errors like dangling modifiers, pronoun-antecedent agreement across sentences, tense consistency in narratives, and context-dependent word choices that simple rule-based checkers miss.
All text processing occurs in real-time with no storage. Your content is never saved to our servers, used for AI training, or shared with third parties. The analysis happens during your session only, and we use enterprise-grade encryption for all data transmission.

Absolutely. The tool is particularly helpful for ESL learners with features like error categorization, detailed explanations, and example-based learning. It helps identify common ESL errors like article usage, preposition errors, verb conjugation, and sentence structure issues with clear corrections.
The tool supports up to 5,000 characters per analysis. For longer documents, we recommend breaking them into sections. The system provides real-time character counting and handles common text formats. For optimal performance, ensure your text has proper spacing and avoid excessive formatting.
