Frequently asked questions
Is this grammar checker really free?
Yes. You can check about 3,000 words at a time, as often as you like (with a short pause if you make many checks per minute).
Does it work for British English?
Yes. Choose English (UK) and it uses British spelling such as colour and organise.
Is it as good as Grammarly?
It catches most common grammar and spelling errors. Premium tools add rewriting and tone suggestions, which this free checker does not.
