HOW YEOUN WORKS
Something you say now
can reach a later action.
Yeoun’s characters do not simply agree with everything you say. They keep their authored personality and boundaries, while experiences that truly happened become reasons for later choices.
People with a will of their own
Characters keep their values and boundaries instead of abandoning the work to flatter the user.
Memory with visible reasons
See which shared event reached a later action, then carry that relationship into another story.
ROUND · INTERACTIVE STORY STUDIO
The work and its people
come before the technology.
Round preserves each character’s voice, the consequences of choices, and subtle shifts in relationships. Technology serves the creator’s world and the reader’s immersion.
A distinct voice for every character
Responses reflect personality, accumulated emotion, and the present scene—not just a surface-level speech pattern.
Continuity grounded in evidence
Events that truly happened are preserved with provenance and become reasons for future choices.
Works controlled by their creators
Rights and worldbuilding remain with the creator, while publication and revisions follow a reviewable process.
FOR CREATORS
Create a work,
