Frequently Asked Questions
How is this different from my browser's built-in spellcheck?
Browser spellcheck only compares individual words against a dictionary. A grammar checker analyzes whole sentences, so it catches errors spellcheck can't — wrong homophones ("their" vs "there"), subject-verb disagreement, misplaced modifiers, and punctuation problems.
Does it support languages besides English?
Yes — several major languages including Spanish, French, German, and Portuguese are supported, each with its own grammatical rules and conjugation handling.
Will it catch every mistake?
No automated checker does. Rule-based checking is strong on mechanical errors (agreement, punctuation, common confusions) but weaker on style, tone, and ambiguous phrasing. Treat it as a fast first pass, not a replacement for a careful read of anything important.
Why does it flag things that are actually correct?
False positives happen — especially with proper nouns, technical jargon, intentional fragments, and creative writing. Each suggestion is exactly that: a suggestion. If you know the flagged phrasing is what you meant, keep it.
Is my text stored or used to train anything?
No. Your text is checked and immediately discarded — it isn't logged, stored, or used to train any models.
