I just tried CHAT GPT-4 for the 4-5th time.

ME:

What do you know about Nostr?

ChatGPT:

I'm sorry, but I'm not familiar with "Nostr" as a specific term or concept. It's possible that you may be referring to something else that I'm not aware of, or it could be a misspelling or abbreviation of a longer term.

If you can provide more context or information about what you're referring to, I would be happy to try and help you to the best of my abilities.

[ED Note: Grammarly tried to remove the unnecessary 'that' in the middle of the sentence.]
