01 / OUR VISION
Your words.
A world that responds.
We envision games where talking to an AI character is part of playing. Characters respond through their own personalities and relationships, and what a player says has meaningful consequences within the game.
From a conversation to a changing relationship and an unfolding story. This is the experience we are working toward.
- 01
Characters with context
Conversations grounded in a character’s personality, the current relationship, and events the player has experienced.
- 02
Interaction with consequences
Connecting dialogue to character expressions and relationship state, so the interaction becomes part of play.
- 03
Stories shaped together
Our goal is to let a player’s words and choices carry forward into relationships and the wider story.
02 / FEATURED GAME
Preparing for launch with AI character chat
Office Princess
The story continues
after work.
A mobile simulation about career growth and relationships with four distinct characters. Reply to an evening message and continue a conversation rooted in the events of your day.
- Dialogue informed by experienced scenes and relationships
- Distinct character voices and expressive reactions
- In-conversation behavior reflected in relationship state
We are preparing AI character chat for the first release. Our longer-term goal is to extend these interactions into more of the game’s experiences.

Start small.
Build hands-on.
Keep improving.
Founded in 2024, BNRB is an independent app and game studio based in South Korea. We take products from concept to development and ongoing operation, improving them through real user experience.
We use Claude Code to develop our apps and games. That hands-on experience informs how we explore AI as a part of game interaction.
