I hope to add an AI summary function to video subscriptions

Clear and concise description of the problem

有些视频知识密度比较低，或者没有太多的时间从头到尾看完，又不想落下里面的知识点。所以希望能够给视频添加一个ai总结功能。

Suggested solution

目前视频转文字相对成熟。可以使用必剪之类视频的api将视频转为文字，然后预处理为书面化的文本，最后进行整理总结。

The issue names no files, tests, or existing entry points. Start by reviewing how Folo represents video subscriptions and handles existing AI or external API integrations, then clarify the transcription provider, summary workflow, and user-facing result. Done would require an agreed scope and a working summary feature for supported video subscriptions.
