Ask HN: Is there a list of startups building on top of ChatGPT out there?

IMHO the ChatGPT startup scene is a house of cards. There is so little known about the longevity of any of these particular models, the internal R&D of the big players, the eventual cost, etc. that as an early stage investor I see too much risk at this point in time.

There's also https://theresanaiforthat.com/ which is extremely comprehensive

Curious as to how does one monetize a directory website without ads?

Matt Wolfe (YouTuber) keeps up with the scene... https://www.futuretools.io/ -- there's a lot of them.
