Is this grammar checker really free?
Yes. There is no sign-up, no word limit per day and no paid upgrade. Each check handles up to 20,000 characters.
Does grammar affect SEO?
Indirectly, yes. Spelling and grammar mistakes reduce trust and quality signals, increase bounce rates and can stop a page matching the searches you want. Google’s quality guidelines treat sloppy content as lower quality.
Can it check British English?
Yes. Choose English (UK) and it will accept British spellings such as “colour” and “organise” and flag American ones.
Is my text saved?
No. Your text is sent securely for checking and is not stored by us.
Why are some suggestions marked as style?
Style suggestions are not errors. They point out wordy or repetitive phrasing you may want to tighten. “Accept all” skips them so you stay in control.
