Question 1

Is it available now?

Accepted Answer

Yes. The Windows app is in the Microsoft Store and available as a direct download, the Chrome extension is live in the Chrome Web Store, and the checker is free to use. Create an account and connect it in a minute.

Question 2

What's free and what's Pro?

Accepted Answer

Spelling and grammar checking is free, in every app, with a plain reason for each fix. Pro is $20 a month and adds one-tap rewrites and natural-tone suggestions, with no daily cap on everyday use. Month to month; you will never discover a price change on a renewal notice.

Question 3

Do I have to pay?

Accepted Answer

No. The checker is free and stays free, with honest daily limits rather than a nag screen. You only pay for Pro if you want the rewrites and the natural-tone help.

Question 4

Is Owlproof a Grammarly alternative?

Accepted Answer

Yes, for the people who want the original job done. In late 2025 Grammarly rebranded and repositioned around AI productivity tools. Owlproof stays a spelling and grammar checker: it checks as you type, explains each fix in plain English, keeps your voice, and costs $20 a month month to month, with a free tier that stays free.

Question 5

Do I need an account?

Accepted Answer

Yes. A free account is what connects the app and extension to you. Sign up with an email and password or with Google. We don't sell it or use it for anything but running your checks.
