AI 分析

痛点:CapCut 把自动字幕功能收进 Pro 付费墙后,免费替代品要么每月 $10-20,要么在免费版加水印;而且上传视频到云端还让创作者担心隐私,用户只想单独完成“字幕”这一步。

目标用户:做 Reels/Shorts/TikTok 的短视频创作者、注重隐私不愿上传素材的剪辑者、需要 Hinglish 等多语种字幕的印度及非英语市场用户

证据:CapCut moved auto captions behind Pro, and most alternatives are $10-20/month or put a watermark on the free tier. I only wanted the caption step, so I built it. ... There's also a desktop app for Mac/Windows (launching soon, one-time price) for long videos, batches, 4K and Hinglish. ...

变现:浏览器免费版(60 秒以内、1080p、无水印)用于获客,桌面版一次性买断(支持长视频/批量/4K/多语种);也可做“一次性买断 + 一年更新”或团队批量授权

MVP:用 whisper.cpp/Whisper WASM 在浏览器本地做语音转录,对齐输出逐词时间轴,提供 3-4 套字幕样式模板,用 WebCodecs/ffmpeg.wasm 渲染并导出 1080p 无水印 MP4 和 SRT,全程不上传;先只做 60 秒以内竖屏视频这一个场景

竞品:CapCut、Veed.io、Submagic、Opus Clip、Descript、Whisper Web / whisper.cpp、Happy Scribe

摘要:作者因 CapCut 将自动字幕移入 Pro、而替代品普遍 $10-20/月或免费版带水印,做了纯浏览器本地运行的逐词字幕工具,免费版支持 60 秒内 1080p 无水印导出并附 SRT,无需账号;后续将推出 Mac/Windows 桌面版,一次性收费,支持长视频、批量、4K 和 Hinglish。帖子本身是产品发布而非用户抱怨,但 CapCut 付费墙变动确实制造了真实需求缺口,且作者已用一次性买断定价验证变现路径。
