This might be interesting if it pulled data from Meta properties (e.g. the Instagram accounts I am following) in order to personally contextualize its responses.
I'm surprised the chatbot on Instagram doesn't already have that. Giving an LLM access to a highly personalized search tool (the scroll algorithm) would make asking for recommendations so much better.
Meta can turn this App into a sort of my assistant. I can dump any link into it. And since those links form the basis of my worldview helping the assistant understand me better. Currently only Google has a monopoly on such a possible futuristic assistant.
