Frequently asked questions
Is Proofread Bot free?
Yes. You get a free daily allowance of proofreading checks in Chrome, Google Docs, the web editor, and the mobile apps. Premium costs $5/month and removes the limit.
Where does Proofread Bot work?
The Chrome, Firefox, and Edge extensions check the text field you are typing in, such as Gmail, Messenger, and web forms. There is also a Google Docs add-on, a web editor, and Android and iOS apps.
How do I check a text field with the extension?
Right-click in the field or press Alt+Shift+P. Issues are underlined in orange, and you can accept or ignore each fix without leaving the page.
Does the Chrome extension work in Google Docs?
No. Google Docs needs the separate Proofread Bot add-on from the Google Workspace Marketplace.
Can I proofread without installing anything?
Yes. Open the web editor, paste or type your text, and review the suggestions in your browser.
