PostPolish is a Chrome extension that instantly converts rough social media replies into fluent, natural English. Designed for non-native English speakers, it allows users to write in their native language or mixed English and then polish their text into clear, ready-to-post messages without leaving the social platform. The extension offers three core features: Polish Reply transforms any draft into smooth English via right-click; Expand Reply naturally lengthens short drafts to make responses more thoughtful; Auto Generate Reply creates fitting replies by highlighting any post on Twitter or LinkedIn. All actions happen within the same window, eliminating the need to switch tabs or apps. Users simply drag their draft text, right-click, and select the desired option. The tool works directly on LinkedIn, X (Twitter), Reddit, and other social sites. It preserves the user’s original voice while ensuring grammatical accuracy and natural phrasing, making global engagement effortless. PostPolish is ideal for non-native English speakers who want to participate confidently in English-language social media conversations. It removes the friction of manual translation and proofreading, enabling faster, more authentic engagement across professional networks and online communities. The extension is built as a lightweight Chrome add-on and integrates seamlessly with existing social platforms. A one-month free coupon (FORPH01) is available at checkout, allowing new users to test the full feature set before committing.
