1st out of 160 teams · UofTHacks · Jan 2026

An online game world where your character keeps living after you log off. It learns how you talk and act, so your friends can still hang out with a version of you while you're away.

Why it won: The hard part was memory: the team built a system that keeps learning from every conversation, storing both the big things you care about and the small quirks in how you type. That is what makes the copy feel like you instead of a generic chatbot wearing your name. And the world runs live with many players at once, so your friends can actually go test whether it fooled them.
