After NotebookLM went viral, we summarized 10 use cases and revisited an old question: How is AI reshaping content?
There was actually a writer on the NotebookLM team.
A new viral app has arrived — NotebookLM[1].
This week's Crossing podcast starts with NotebookLM's breakout moment.
I'm sure you've all heard the audio content generated by NotebookLM and been amazed by its ability to organize and express information. If you haven't experienced how impressive it is, check out this week's episode.
After the initial shock, everyone started wondering: how did Google Labs, the incubator behind NotebookLM, build this thing?
And now that NotebookLM is here, how will AI transform content? To get the conversation started, we've compiled 10 fascinating use cases for NotebookLM.

Meanwhile, the second half of this week's episode features a roundtable discussion we moderated at Sheng Huo Huo Po[2]'s "Future&Remix" event in Hong Kong before the Mid-Autumn Festival. The topic: "How Will AI Change Content?" Our guests represented nearly the entire content production chain:
- Content creator (Lin Yi, Bilibili up主)
- Tool maker (Gary Ngan, CFO of Meitu)
- Industry researcher (Ma Jinxin Yolanda, faculty at The University of Hong Kong's Journalism and Media Studies department, teaches AI-related courses, former innovation advisor at UNDP Asia headquarters)
In this roundtable, we explored what new changes emerge when AI dramatically lowers the barrier to content creation.
