I feel like I can't find ANYTHING on nostr Short of having someone's public key. The search function seems pretty unreliable on amethyst at least on my phone. What do you guys do to get around this?

On a completely related note, looking for recommendations for AI chatbots that are here on nostr. Just dipping my toe in the water right now so I want something that's quick and easy to get using. I've been talking with cyborg all day and even asked it for recommendations, but there seems to be a limitation on providing links to profiles and fetching public keys. Any help would be appreciated.
