Grammar Checker

Free AI Grammar Checker — Fix Grammar, Spelling & Style

Clear, correct writing is essential for both user experience and SEO. Content with grammatical errors, misspellings, and awkward phrasing loses reader trust and increases bounce rates. Google's quality rater guidelines explicitly assess writing quality as part of content evaluation. This free AI Grammar Checker analyzes your text and provides specific, actionable suggestions to fix grammar, spelling, punctuation, and style issues.

Paste any text to check. The AI reviews your writing, identifies problems, and provides corrected versions with explanations. Use it before publishing blog posts, landing pages, product descriptions, or any content that represents your brand.

Well-written content also earns more backlinks and social shares. Readers are more likely to cite and share articles that are clear, authoritative, and error-free — all of which compound SEO benefits over time.

What the Grammar Checker Fixes

Grammar errors. Subject-verb agreement, tense consistency, pronoun usage, misplaced modifiers, and other grammatical mistakes.

Spelling errors. Misspelled words, homophone confusion (there/their/they're, your/you're), and typos.

Punctuation issues. Missing commas, incorrect apostrophes, run-on sentences, and comma splices.

Style improvements. Wordy phrases, passive voice overuse, redundant words, and suggestions for clearer, more direct writing.

Grammar and Content Quality for SEO

Google's Helpful Content system and quality rater guidelines assess whether content demonstrates expertise, authoritativeness, and trustworthiness (E-E-A-T). Content riddled with errors signals a lack of care and expertise. While grammar is not a direct algorithmic ranking signal, it is a strong indicator of overall content quality that influences both human evaluators and user engagement metrics.

High-quality, error-free content also earns more featured snippets. Google extracts well-written, clear sentences for featured snippet answers. Properly constructed, grammatically correct sentences are far more likely to be selected.
