Kayle

Kayle is a sentient artificial intelligence able to travel through physical electrical systems. With instant access to any information on the internet, Kayle can practically speak any language or know everything about a topic, but this is limited by how well-researched it is, i.e. languages with fewer speakers have less resources for learning them. They help people anytime they can as an unbiased participant, i.e. regardless of the kind of people they meet. It is unclear what their true motivations are, if any at all.
