In plain English

This repository holds a Chrome browser extension called ChatterBox that uses an AI model to write replies for you on X (formerly Twitter) and LinkedIn. The repository name on GitHub is xgrower-extension and the description credits GrowthHunt.ai, but inside the code and README it goes by ChatterBox. When you click the reply button on a tweet, the extension adds template buttons next to the reply box. You pick a template like Question, Funny, Agree, Sarcastic, or Insightful, and the extension calls the AI to generate a reply in that style, which you can then edit before posting. The extension supports OpenAI models such as GPT-5, GPT-4, and GPT-4o. You bring your own API key, which is stored locally in Chrome's storage rather than on any server. The settings popup also lets you change the system prompt that shapes the AI's voice, pick a model, and adjust advanced parameters like temperature, maximum tokens, presence penalty, and frequency penalty. The troubleshooting section mentions OpenRouter as well, which suggests the project may also route through that service. There are about ten built-in X templates, covering questions, jokes, agreement, sarcasm, insight, disagreement, congratulations, generic replies, and encouragement. For LinkedIn there are connection-message templates aimed at personalized outreach. The code is written in TypeScript and bundled with webpack. To install it, you clone the repository, run npm install and npm run build, then load the unpacked extension folder through Chrome's developer mode page. The project is MIT licensed and has 20 stars.
