PublicAI is a platform that uses your input to improve on AI, and pays you to do so.
When I say "pays you", obviously I'm talking about micro income that you can earn by completing tasks.
They call themselves a "distributed AI training network".
The main goal is to train AI with diverse data, because according to PublicAI, data used to train AI can be a bit monotone.
PublicAI doesn't specify where you'd actually be doing that anonymously or not but, I suspect, complete anonymity wouldn't be possible.
But remaining pseudonymous might.
