## Overview

Grammar Guru is a lightweight Chrome extension for anyone who writes in the browser — emails, social posts, blog drafts or community replies. Once installed, it activates as you type and surfaces suggestions on grammar, punctuation, style and tone, which you can accept selectively so your own voice stays intact.

The extension's standout feature is tone transformation. Rather than only fixing mistakes, it lets you reframe the same message as professional, casual, persuasive or informative, which is useful when the same idea has to land differently with a manager, a customer or a friend. It integrates directly into the pages where you already write, so there is no switching between apps or copy-pasting into a separate editor.

The listing describes Grammar Guru as suited to professionals polishing emails and reports, students working on essays and assignments, content creators writing posts and articles, and non-native English speakers navigating the subtleties of the language. It reports a small user base of around 184 users and a 3.0 rating from two reviews, and the developer discloses handling personally identifiable information while stating that data is not sold to third parties and not used for unrelated purposes.
