About Owlproof

Owlproof checks your spelling, grammar, and punctuation as you type on any web page, in any text box, comment field, or web email. That is the whole product. An owl pin appears at the corner of the box you are typing in, with a count of what it found. Hover the pin, or Tab to it and press Enter, and every suggestion is listed with the fix beside it and a plain-English reason. Accept one, accept them all, or dismiss the ones you meant. - Spelling, grammar, and punctuation, caught and clearly explained - Underlines right in the field, including plain text boxes and text areas - Add words to your own dictionary - Keyboard friendly: the pin and every button work with Tab, Enter, and Escape - One pin, not two: if you also use the Owlproof desktop app, it steps aside on web pages the extension covers Spelling and grammar checking is free. Pro ($20 a month, cancel any time) adds Rewrite, which makes a paragraph sharper or more natural in one click. Owlproof is made by Mako Logics LLC. Privacy policy: https://owlproof.app/privacy
