AI 分析

痛点：现有 YouTube 字幕下载工具大多按单视频收费、强制注册或限制批量导出，用户需要免费/低价地整频道批量获取字幕并转成文本、Markdown、SRT 等格式。

目标用户：内容研究者、AI/RAG 开发者、Obsidian/Notion 知识管理用户、营销人员、记者、YouTube 频道运营者。

证据：every tool I tried did one video per paste, or charged per video, or made me sign up first. They all say "free", but it's more like freemium, y'know?

变现：Freemium：基础免费限制少量视频/单次批量；Pro 订阅解锁整频道批量、更高配额、优先队列、API/MCP 访问、团队协作和云同步。也可做一次性买断的桌面版或按 API 调用量计费。

MVP：2 周内用 Next.js + yt-dlp/YouTube Transcript API 做网页版：粘贴视频/播放列表/频道 URL，批量拉取字幕，支持 TXT、SRT、VTT、Markdown、JSON，打包 ZIP 并生成 manifest；免费 50 个视频，付费解锁 500+/频道全量。

竞品：DownSub、NoteGPT、Tactiq、YouTube Transcript、yt-dlp、Kome.ai、Supadata

摘要：发帖人因现有 YouTube 字幕工具按单视频收费、强制注册或限制批量，自建了免费整频道字幕下载工具 ScriptHaul，支持一次 500 个视频、7 种格式、浏览器扩展和 MCP。该需求真实存在且竞品已在收费，但免费工具多、差异化有限，变现需靠高频批量、API/MCP 或团队订阅。
