痛点：字幕工具强制把视频上传到云端，且月费20-40美元；用户需要多个工具才能完成转录、样式编辑和字幕烧录，隐私素材也不能离开本地。

目标用户：需要给视频加字幕的视频创作者、自媒体、剪辑师，尤其是注重素材隐私、同时使用Windows/macOS、希望本地一次性完成转录和烧录的用户。

证据：the tools wanted the file uploaded to their servers first and $20-40 a month after.

变现：一次性买断授权为主，例如29-49美元；可增加批量处理、团队授权、高级样式包等付费升级，避免强制订阅。

MVP：2周MVP：做一个Windows/macOS桌面端，支持拖入视频、本地Whisper转录、基础字幕时间轴编辑、导出SRT/VTT和烧录MP4。先不做多语言翻译和复杂样式，验证“本地隐私+一站式字幕”需求。

竞品：MacWhisper、Descript、Submagic、VEED、Kapwing、Opus Clip、Whisper + ffmpeg 脚本、Aegisub

摘要：作者因现有字幕工具强制上传视频且月费20-40美元，开发了本地运行的Sablate，用Whisper转录，支持翻译、字幕样式和烧录，覆盖Windows/macOS。它验证了隐私优先、本地处理的字幕工具存在付费替代空间，但市场已有MacWhisper、Descript、Submagic等较多竞品。
