Frequently Asked Questions
Is this grammar checker really free?
Yes. Unlimited checks, no signup, no character cap (per request up to 20,000 chars), no watermark.
How is this different from Grammarly?
Grammarly's paid plan offers tone rewriting and longer context. Our free checker covers the same core fixes — spelling, grammar, punctuation, and style — without an account or a download.
Does it support British English?
Yes — pick en-GB above and it'll prefer 'colour' over 'color', 'organise' over 'organize', and UK punctuation rules.
Is my text private?
Yes. Text is sent to the LanguageTool API for analysis and immediately discarded. We don't log, store, or train on your content.
Will it catch every mistake?
It catches most spelling, grammar, and punctuation issues plus common style problems. It won't fact-check, restructure paragraphs, or rewrite for tone.
