The irony of this article being fully AI generated...
Anyway, it's over for Perplexity. They never had a great a product and the only reason for using them, was when they offered Pro accounts for free. Many people joined. Me included. But with a "meh" product and the general AI business not being very sticky, they lost quite harshly.
I thought they might be able to make money as a search api/index, but this article closed the book.
