I just tried accessing it. When you visit bard.google.com on Firefox it just gives you a generic intro after logging in. I was a little confused and logged in with Chrome, where I now saw a "join waitlist" button. Guess they don't want Firefox user using it.

Overall this just seems underwhelming. Most HN comment's I've read are people saying it doesn't work with their account, doesn't work in their country, doesn't work for some other reason, or works and is very limited compared to ChatGPT.

Google what have you been up to?
