Frequently asked questions
Is my text stored anywhere?
No. The checks run in your browser, so your writing never leaves your device.
Does it replace a full grammar checker?
It catches the most common slips quickly. Always read your work aloud once more: it is the best way to catch missing words and awkward sentences.
Why is passive voice flagged?
Passive sentences are not wrong, but active sentences are usually shorter and clearer. Use passive voice when the person doing the action is unknown or unimportant.
