Check and correct grammar, spelling, punctuation, and style in your text instantly
Our AI grammar checker achieves approximately 95% accuracy for standard English text. It uses advanced natural language processing algorithms to detect grammar errors, spelling mistakes, punctuation issues, and style problems. While highly accurate, it's recommended to review suggestions, especially for complex or specialized texts.
The tool detects: spelling mistakes (typos, misspellings), grammar errors (subject-verb agreement, tense consistency, sentence structure), punctuation issues (missing commas, incorrect apostrophes, semicolon usage), style problems (wordy phrases, passive voice, informal language), and capitalization errors (proper nouns, sentence beginnings).
Yes! The grammar checker works well with technical, academic, business, and creative writing. It adapts to different writing styles and maintains proper terminology. For highly specialized fields (medicine, law, engineering), it focuses on general grammar rules while preserving domain-specific vocabulary and formatting.
The grammar score (0-100) evaluates your text based on error frequency, sentence complexity, vocabulary usage, and readability. Scores above 90 indicate excellent writing, 80-90 is good, 70-80 needs improvement, and below 70 requires significant revision. The score updates in real-time as you make corrections.
