+## 🌐 Web Application (Next.js)
+
+In addition to the command-line script and FastAPI service, this project also provides a fully functional web user interface. This interface aims to provide a more intuitive and convenient podcast generation and management experience, exposing complex backend functions through friendly frontend operations to users.
+
+### ✨ Core Features
+
+*   **Web Operation Interface**: Intuitive and friendly web interface that makes the podcast generation process clear at a glance.
+*   **Micro User System Integration**: Supports user login, registration, points and billing functions, building a complete user ecosystem.
+*   **Podcast Creation and Configuration**: Allows users to enter topics through forms and configure TTS characters, volume and speed parameters.
+*   **Real-time Progress Tracking**: Displays the status and progress of podcast generation.
+*   **Podcast Playback and Management**: Integrates an audio player for users to listen to generated podcasts and may provide functions for managing historical podcasts.
+*   **API Interaction**: Seamless communication with the backend Python service through APIs, including podcast generation, status queries, and audio streaming.
+
+### 🚀 Quick Start (Web)
+
+1.  **Install Node.js**: Please ensure Node.js is installed on your system (LTS version recommended).
+2.  **Install Dependencies**: Enter the `web/` directory and install all frontend dependencies.
+    ```bash
+    cd web/
+    npm install
+    # or yarn install
+    ```
+3.  **Start Development Server**:
+    ```bash
+    npm run dev
+    # or yarn dev
+    ```
+    The web application will start at `http://localhost:3000` (default).
+4.  **Build Production Environment**:
+    ```bash
+    npm run build
+    # or yarn build
+    npm run start
+    # or yarn start
+    ```
+
+### 🐳 Docker Deployment
