I made a small site to make shadowing YouTube videos easier

I practice English by shadowing YouTube videos, and I kept dragging the timeline back to repeat a sentence. So I built a site that plays one sentence at a time, pauses for you to repeat, and shows which words came through clearly.

AI 分析

痛点:用YouTube练英语影子跟读时,需要反复拖动进度条回放同一句,且缺少逐句停顿跟读和发音清晰度反馈的工具。

目标用户:用YouTube视频练口语/听力的英语学习者,尤其是采用shadowing跟读法的自学者(非英语母语者、备考雅思托福人群)。

证据:I practice English by shadowing YouTube videos, and I kept dragging the timeline back to repeat a sentence. So I built a site that plays one sentence at a time, pauses for you to repeat, and shows which words came through clearly. / Built with Vue and Cloudflare Workers (Whisper for speech). Free, no sign up.

变现:Freemium订阅:免费每日N句/限时长,付费(约$5-9/月)解锁无限视频、发音打分报告、生词本与学习进度追踪;或按年买断的终身授权;也可做面向雅思/托福口语培训机构的B端授权。

MVP:2周MVP:粘贴YouTube链接→用Whisper按句切分并生成时间轴→逐句播放并在句尾自动暂停留白跟读→浏览器录音回放对比+基于Whisper词级置信度的发音清晰度打分。前端Vue/Svelte + Cloudflare Workers,缓存转写结果降低Whisper成本,先不做账号体系。

竞品:Language Reactor、Trancy、Migaku、LingQ、YouGlish、eJOY English、Glossika

摘要:开发者为了自己练英语影子跟读时反复拖进度条的麻烦,用Vue + Cloudflare Workers + Whisper搭了shadow-ez.com:逐句播放、自动停顿等待跟读,并显示哪些词发音清晰,免费且无需注册。痛点真实且是自用验证过的重复性工作流,独立开发者复刻成本低;但语言学习赛道已有Language Reactor、Trancy、LingQ等成熟付费竞品,且原帖未出现任何付费意愿或收入数据,需求强度仍属个人级。
