我们为什么构建 TLDW
I’m excited to launch a side project I’ve been building with two friends: TLDW (Too long; didn’t watch), a tool that helps people learn from long YouTube videos.
我很高兴推出一个我和两个朋友一起构建的副项目：TLDW（太长；没看），一个帮助人们从长时间的YouTube视频中学习的工具。
TLDW was inspired by my own pain points when learning from YouTube.

Apparently, many other people feel the same, because YouTube is now the biggest podcasting service in the US. Yep, YouTube, not Apple Podcasts or Spotify.
显然，许多人有同样的感觉，因为YouTube现在是美国最大的播客服务。没错，是YouTube，而不是Apple Podcasts或Spotify。
When I recommended my followers do the same, I noticed that many people didn’t have the attention span to sit through these hour-long videos. Instead, they tend to toss the link to an AI tool (say Gemini or NotebookLM) and get it to generate a text summary.
当我建议我的追随者也这样做时，我注意到许多人没有耐心坐下来观看这些一个小时的视频。相反，他们倾向于将链接扔给一个AI工具（比如Gemini或NotebookLM），让它生成文本摘要。
