🧠 Tweak AI Prompts – Chrome Extension

Boost your productivity by injecting a ✨ Tweak button into AI input boxes (ChatGPT, Claude, Gemini, DeepSeek) that optimizes your prompts for better AI responses.

✨ Features

• Injects a "Tweak Prompt" button directly into supported AI chat UIs.
• Uses the OpenRouter API to optimize the written prompt.
• Works with:
  • ChatGPT (chat.openai.com)
  • Claude (claude.ai)
  • Gemini (gemini.google.com)
  • DeepSeek (chat.deepseek.com)
• Prompt output is returned as plain optimized text — no clutter.

🧩 How It Works

1. On AI input boxes, a ✨ button appears once you start typing.
2. When clicked, your prompt is sent to OpenRouter using the deepseek-chat model.
3. You get back a smarter, more specific version of your prompt, which replaces the original input.

🚀 Installation (Dev)

1. Clone this repo:

   git clone https://github.com/yourname/tweak-extension.git
   cd tweak-extension

2. Create a .env file:

    VITE_OPENROUTER_API_KEY=your_openrouter_api_key_here
    VITE_BACKEND_URL=your_backend_url

3. Run the dev build:

npm install
npm run build

Go to chrome://extensions/, enable Developer Mode, click Load unpacked, and select the /dist folder.

🔧 Configuration Make sure to include your OpenRouter key in the .env file as:

    VITE_OPENROUTER_API_KEY=your_key
    VITE_BACKEND_URL=your_backend_url

You can get one from https://openrouter.ai/
