Ever wondered what it is like to be...?
...be their muse and guide their story.
Ever wondered what it's like to fight a dragon?
Let's find out, with MUSE.
A simulation of living worlds with endless possibilities.
MUSE Living Worlds will be our first medium built on MUSE, where you influence what characters notice, remember, and choose — and the world responds with consequences.
A living world in motion, where dopamine, weather, and memories all shape what happens next
You do not control the character.
You are their muse. You suggest — the rest emerges.
MUSE allows for realistic behaviors, but more importantly, by playing the role of a muse, and not simply controlling a character, it enables experiences where perspective-taking isn't optional—it's inevitable. Anyone can embody any character: different ages, abilities, identities, or even fantastical beings.
The MUSE Ecosystem—or MUSE for short—is our core platform. A scientifically grounded multi-tool platform for authoring, compiling, and running living worlds. Designers and researchers build modular systems of psychology, biology, and environment; MUSE compiles these into deterministic simulation logic that drive emergent character behavior over time—designed to bring many thousands of characters to life all at once.
At the core is our FONT Simulation Engine, powering applications ranging from interactive fiction and narrative media, like MUSE Living Worlds, to research-grade behavioral modeling and applied simulation in education, healthcare, and beyond.

MUSE is built on transparent, scientifically grounded system models—not AI word matching or branching scripts—that we can modify as human understanding grows.
Behavior isn't generated. It emerges.
When a character snaps at you, it's because they're exhausted and hungry and you just reminded them of something painful. Not because a language model calculated that "snapping" was statistically likely. This is why MUSE characters feel real.
