Show HN: Turn any webpage/video into a summary, podcast, or mindmap

2 rriley 0 7/3/2025, 10:59:40 PM unrav.io ↗

This is a small tool called unrav.io. It's a bookmarklet that lets you transform any webpage in place using AI.

No extensions, no copy/paste. Just click and choose what you want to do:

- Summarize the page

- Turn it into a podcast

- Visualize it as a mindmap

- Chat with the content

Demo: https://www.youtube.com/watch?v=c5QdRBykxFU

Try it here: https://unrav.io

It’s early, but surprisingly useful already. Curious what people think.
