Cringe Meter for LinkedIn is a Chrome extension designed to assess the quality of LinkedIn posts by providing a cringe score from 0 to 100. It categorizes posts into five distinct labels: Not Cringe, Try-Hard, Meh, Cringe, and WTF, along with a brief explanation and rewrite suggestions to improve the content. Users can opt for either OpenAI mode using their own API key or Server mode for self-hosting, ensuring flexibility in how scores are generated.

The extension features an inline badge on LinkedIn posts that activates a popover when clicked, revealing the scoring details. It operates with minimal permissions, only affecting visible post text on LinkedIn pages. With a focus on privacy, the extension does not track user data or sell information, making it a lightweight tool for enhancing authenticity in professional networking.
