Other Polyverse Projects

Outside of Ryzom Core, Polyverse works on several other projects.

AI Chat Characters

Polyverse builds AI characters that hang out in group chats. Ruri is a catgirl who lives on simulated Mars. Aoi is a cute anime girl you can invite to your Discord server to chat with you and your friends. They're both used to explore how memory, personality, and group dynamics work for AI in social settings. You can also make your own AI friend for your Discord server.

Embedded GPU & MCU Emulation

Polyverse develops emulators and development tools for Bridgetek's BT8xx and FT9xx embedded display controllers, used for prototyping firmware and UI flows without requiring physical hardware.
