How It Works

This tool uses a rule-based approach to detect common writing errors. It checks your text against multiple rule categories:

1. Spelling — Compares words against a built-in dictionary of commonly misspelled words and their corrections.
2. Grammar — Detects frequent grammar mistakes such as subject-verb disagreement, incorrect word usage (e.g., "their" vs "there"), and doubled words.
3. Punctuation — Identifies missing capitalization at the start of sentences, repeated punctuation, and spacing issues around punctuation marks.
4. Style — Suggests improvements for wordiness, passive constructions, and informal language in formal text.
