+## 🤖 模型与功能增强 (Day 15 晚)
+
+### 1. GLM-4.7-Flash 升级
+
+**文件**: `backend/app/services/glm_service.py`
+
+将文案洗稿模型从 `glm-4-flash` 升级为 `glm-4.7-flash`：
+
+```python
+response = client.chat.completions.create(
+    model="glm-4.7-flash",  # Upgrade from glm-4-flash
+    messages=[...],
+    # ...
+)
+```
+
+**改进**:
+- 响应速度提升
+- 洗稿文案的流畅度和逻辑性增强
+
+### 2. 独立文案提取助手
+
+实现了独立的文案提取工具，支持从视频/音频文件或 URL 提取文字。
+
+#### 后端实现 (`backend/app/api/tools.py`)
+
+- **多源支持**: 文件上传 (MP4/MP3/WAV) 或 URL 下载
+- **智能下载**:
+  - `yt-dlp`: 通用下载 (Douyin/TikTok/Bilibili)
+  - `Playwright`: 智能回退机制 (Bilibili Dashboard API, Douyin Cookie Bypass)
+- **URL 自动清洗**: 正则提取分享文本中的 HTTP 链接
+- **流程**: 下载 -> FFmpeg 转 WAV (16k) -> Whisper 识别 -> GLM-4.7 洗稿
+
+#### 前端实现 (`frontend/src/components/ScriptExtractionModal.tsx`)
+
+- **独立模态框**: 通过顶部导航栏打开
+- **功能**:
+  - 链接粘贴 / 文件拖拽
+  - 实时进度显示 (下载 -> 识别 -> 洗稿)
+  - **一键填入**: 将提取结果直接填充到主输入框
+  - **自动识别**: 自动区分平台与链接
+- **交互优化**:
+  - 防止误触背景关闭
+  - 复制功能兼容 HTTP 环境 (Fallback textArea)
+
+### 3. 上传视频预览功能
+
+在素材列表 (`frontend/src/app/page.tsx`) 中为上传的视频添加预览功能：
+- 点击缩略图弹出视频播放模态框
+- 支持下载与发布快捷跳转
+
