关于 5tldr

用 AI 更聪明地学习

我们做 5tldr,是因为难点已经不是“找信息”,而是“判断什么值得你投入注意力”。

我们的使命

5tldr 帮人们快速判断长内容的价值,留下有用部分,并建立真正会回看的工作流。

把摘要当作决策工具

第一件事,是先判断这个来源值不值得深入阅读。

让输出可以复用

摘要应该能进入笔记、资料库、导出和后续复习。

对边界保持诚实

AI 能帮助筛选和理解,但不会替代判断。

我们优化的方向

产品围绕清晰、速度和复用来设计,而不是只给一个泛泛的摘要。

Our Story

From a personal frustration to a tool used by thousands.

5tldr started in late 2024 as a personal tool. The founder spent hours every week watching hour-long YouTube lectures and reading 30-page reports, only to realize that most of the value came from 5 to 10 key points. The question was simple: what if you could get those points in seconds instead of hours?

We built a prototype, shared it with students and researchers, and the feedback was overwhelming. People used it not to skip reading, but to decide what deserved a deep read. That insight shaped the product: 5tldr is a triage tool for long-form content, not a replacement for thinking.

Today, thousands of students, teachers, researchers, and professionals use 5tldr to turn videos, articles, PDFs, and papers into structured notes, study guides, and reusable knowledge workflows. We remain a small, focused team committed to building one thing well.
