Proofr

Private AI that proofreads, rewrites in any tone, and translates. Works on your device, no account needed. Proofr is an AI proofreader, rewriter, and translator that lives in your right-click menu. Select any text on a page, then pick what you want: fix the grammar, rewrite it in a different tone, or translate it. You get a cleaner version in a second, right where you were typing.

Most writing tools send everything you type to their servers and make you sign in first. Proofr works differently. By default it runs on your own computer using Chrome's built-in AI, so your text never leaves your machine. There is no account, no login, and no API key to set up.

What you can do:

• Proofread. Fix grammar, spelling, and punctuation while keeping your own wording and voice.
• Rewrite in a tone that fits: Professional, Friendly, Concise, Plain English, LinkedIn, Marketing, Executive, Academic, or News.
• Translate into English, Spanish, French, German, or Japanese.

How it works: 1. Install it. There is nothing to sign up for. 2. Select some text on any page. 3. Right-click and choose Proofr, then pick proofread, a tone, or translate. You can also press Ctrl+Shift+R for a quick fix.

In an editable field like a Gmail draft or a comment box, Proofr replaces your text in place. Everywhere else it shows the result in a small panel you can copy from.
