Right point, thanks for the feedback. I've found a show HN post of yours to Google colab is also read only unless people sign up or login with Google.

I am assuming read only links are allowed so this is now public to read. Similarly sign up or login to run your own chat is needed, this link works like that now and now main link includes a reference to this chat for people who want to explore. : https://pingu.audn.ai/chat/3fca0df3-a19b-42c7-beea-513b568f1...
