Eposyne Architect narrative structure view showing entities and branching storylines

What is Eposyne?

Eposyne is an AI-powered narrative design platform for game developers, writers, and TTRPG creators. Eposyne Architect turns your existing lore into structured, engine-ready narrative data. Eposyne Director is a runtime AI Game Master that drives dynamic stories in your game. It is built to run on-device through its native SDK, which is not yet available; today, developers use the hosted Director beta.

Two tools. One pipeline.

This is amazing! One file, very generic, and it mapped it out perfectly.
