Why Use Our Grammar Checker

Writing Scores & Tone

Get scores for clarity, engagement, delivery, and correctness. See a visual tone indicator showing whether your writing is formal or casual.

Grouped Error Categories

Errors are organized by type, including grammar, spelling, punctuation, style, and clarity, so you can focus on the areas that need the most improvement.

Frequently Asked Questions

Our grammar checker catches grammar errors (subject-verb agreement, tense consistency, misplaced modifiers), spelling mistakes, punctuation errors (commas, semicolons, apostrophes), style issues (passive voice, wordiness, repetition), and clarity problems (ambiguous phrasing, overly complex sentences).

We support American English (US), British English (UK), Australian English (AU), and Canadian English (CA). Select your dialect in the dropdown to get region-specific suggestions, like "color" vs "colour" or "realize" vs "realise."

The writing scores rate your text on four dimensions: Clarity (how easy it is to understand), Engagement (how interesting and compelling), Delivery (tone and voice consistency), and Correctness (grammar and spelling accuracy). Each is scored from 0 to 100.

The tone indicator analyzes your writing style on a spectrum from Formal to Casual. It considers factors like sentence length, vocabulary complexity, use of contractions, and overall voice. This helps you ensure your writing matches your intended audience.
