🤖 PromptBuddy — Chrome Extension

PromptBuddy is a Chrome Extension that helps you write better prompts on ChatGPT.
It automatically analyzes what you type and provides instant feedback and contextual hints, right above ChatGPT’s input box.

✨ Features

🧩 How It Works

1. As you type a message in ChatGPT, the extension automatically sends your text to the backend API.
2. The backend analyzes your prompt using a trained classifier model.
3. If potential improvements are found, a popup appears above the input box with feedback.
4. Clicking the ℹ️ button shows a short hint explaining the reasoning behind that feedback.

🚀 Installation (Manual / Developer Mode)

1. Clone this repository:

git clone https://github.com/robbype/PromptBuddy-Chrome-Extension.git

2. Change Backend Endpoint

By default, the extension connects to the backend API through a local FastAPI server at:

const res = await fetch("http://localhost:8000/analyze", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ text })
});

If your backend is deployed elsewhere (for example, on Render, Vercel, or via Ngrok), you need to replace the endpoint URL with your own API address inside content.js.

Example:

const res = await fetch("https://your-backend-domain.com/analyze", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ text })
});

3. Open Google Chrome, then go to:

chrome://extensions/

4. Enable Developer mode (top right corner).

5. Click “Load unpacked” and select the folder you cloned.

6. Visit chat.openai.com or chatgpt.com

The extension will automatically activate when you start typing!
