Engineering for virtual worlds and AI-native chat.
Polyverse OÜ develops tooling at the intersection of game engines, GPU & CPU emulation, and AI chat systems. The focus is on low-level engineering that enables artists, designers, and communities to build worlds, characters, and interactive experiences.
Current Focus
Development of AI chat friends that live naturally across group chats, livestreams, and communities. Characters like Ruri and Aoi test new behaviour systems, memory models, and service architectures.
What Polyverse Builds
Bridging low-level engineering with creative tools.AI chat friends & tooling
Infrastructure and frontends for AI characters that participate naturally in group chats: long-context KV-cache continuity, Discord integrations, Twitch chat tooling, and X/Twitter interfaces used by Ruri and Aoi.
Game engine & dev tools
Contributions and extensions to large C++ codebases, asset build pipelines, exporter tools, and other supporting systems. Focus on practical improvements that make iteration faster for designers and programmers.
Embedded GPU & MCU emulation
Emulators and visual development tools for embedded display controllers and microcontrollers, enabling hardware vendors and studios to iterate on firmware and UI flows more quickly during development.
Flagship
Polyverse AI Chat Platform — real-time characters for communities and games.The Polyverse chat platform treats AI as participants inside shared spaces. Characters like Ruri and Aoi operate across Discord, Twitch, and X/Twitter, using long-running context and platform-specific signal filters to maintain conversational presence instead of single-shot replies.
The same architecture can power community bots, creative tools, or in-game NPC dialogue. It's built around distributed dispatch, persistent character state, and platform-specific behaviour layers.
Open Source & Long-Running Work
Engines, infrastructure, and community projects.
Polyverse OÜ maintains testing servers and contributes directly to the development of the Ryzom Core open-source MMORPG engine, including the audio engine, asset build pipeline, exporter tools, and technical documentation.
More information: wiki.ryzom.dev. Example work can be found in the Ryzom Core GitHub history.
Jan also contributes fixes and improvements to open-source projects that Polyverse uses in production.
About the Developer
Systems engineering, engines, and AI chat architecture.Polyverse OÜ was founded by Jan Boon (Kaetemi), a developer with a background in large-scale game engine codebases, rendering systems, embedded GPU tooling, and persistent AI characters. His work connects low-level performance engineering with practical tools that empower artists and interactive systems. Jan is available for contract work on AI chat infrastructure, game engine tooling, and embedded graphics.
The goal behind Polyverse is consistent: build infrastructure that feels invisible to creators while enabling complex behaviour, continuity, and fluid interaction.
- Long-term contributor to the Ryzom Core open-source MMORPG engine.
- Developer of GPU and CPU emulation tools used for embedded hardware and UI prototyping.
- Designer of the distributed infrastructure powering Polyverse AI chat characters.
- Contributor to open-source tools used in Polyverse's custom inference and serving stack.
