Okay devs, this one caught me off guard.

I was testing out Google's NotebookLM, expecting it to be another AI summarizer. Cool, but whatever.

Instead, I found this "Studio panel" with something called Video Overview — and in less than 3 minutes, it literally turned a block of copied text and a YouTube transcript into a fully narrated explainer video with slide transitions, quotes, and everything.

No Adobe Premiere. No voiceover. Not even a script.

Check out the full video on my Youtube Channel

How it works:

You can paste copied text, link a YouTube video, or add docs

Then you hit “Generate Video Overview”

It gives you a narrated breakdown of the content

Bonus: you can customize tone, style, and export it right away

I tested it with AI tools and quantum networking stuff, and the result was clean enough to use in an actual client pitch or course video.

Maybe not perfect yet, but honestly? As someone who’s spent hours editing screencasts — I’m not complaining.

Anyone else tried this?
