Submit any English text (50-2000 characters) and our AI analyzes it for grammar, spelling, vocabulary, style, and punctuation errors. You get a score (0-100), CEFR level assessment, corrected text with highlighted changes, detailed error explanations, an improved version, and personalized writing tips.

Each correction costs 1 credit. New users receive free credits upon signup. Subscribers get unlimited corrections. No account is needed to view the page, but you must sign in to submit text.

The AI detects five categories of errors: grammar (tense, agreement, article usage), spelling (misspelled words), vocabulary (word choice, collocations), style (awkward phrasing, wordiness), and punctuation (commas, periods, semicolons).

Based on your vocabulary range, grammar complexity, and error patterns, the AI estimates your writing proficiency on the CEFR scale from A1 (Beginner) to C2 (Proficiency). This helps you understand your current level and track improvement.

Yes! The detailed error analysis and scoring help you identify weaknesses in your writing. Regular practice with the correction tool can improve your grammar accuracy, vocabulary range, and overall writing quality for English proficiency exams.
