Game AI Done Better


At Kythera AI, our mission is to empower studios to create unique and compelling game AI tailored to their needs. We do not believe in a one-size-fits-all approach; all our solutions are built to be extendable and customisable to fit a studio's specific needs. Furthermore, Kythera AI’s core library and AI tools enable developers to create custom and sophisticated AI solutions faster and more cost-effectively.

Our latest toolset, Kythera 2, is developed by industry-leading experts, reflecting years of collaboration with studios to understand and address developers' challenges. This is reflected in our core design pillars.

Highlighted Features


Surface Navigation

Allows entities to crawl on walls, cling to ceilings, and move naturally across surfaces of any orientation.

Kythera can analyze walls, ceilings, and complex geometry, plan sensible routes across them, and move entities smoothly along those paths, with natural changes in orientation and speed when transitioning between surfaces.

AI Planning

Kythera AI ships with a state-of-the-art AI Planning system. This is more expressive than the well-known Goal-Oriented Action Planner, enabling your NPCs to deliberate about their actions and environment.

Combined with Kythera AI's other features and tight integration with Unreal's AI system, such as behavior trees, developers can create much more intelligent NPCs and exciting gameplay.

Moving NavMesh

Kythera AI makes it effortless to generate navigation meshes on moving geometry. Our library functions enable navigation meshes to merge, allowing for exciting gameplay moments such as boarding sequences between moving ships.

It also supports all of our other ground navigation mesh features.

NavMesh Extensions

Kythera AI provides support for multiple-sized entities on a single NavMesh out of the box. Our NavMesh generation pipeline is built with flexibility in mind, allowing you to access, modify, and extend its capabilities - for example, allow characters to conform to their wading depth constraints when moving through water, or create entities that avoid well-lit areas to better hide from players.
