The engine beneath every world

The Kawabunga Architecture

Voice, knowledge, memory, orchestration, and rendering work together to make every world respond in real time.

Responsive world direction

Orchestration

The Orchestrator brings characters, narration, and the world together in real time, deciding who speaks, what happens next, and how the story responds to you.

Your story, your style

Shape the Experience

Turn it on for a dynamic, narrator-led experience or turn it off for a direct, character-focused conversation. Change its personality and the entire experience changes with it.

Character voice system

Sound Library

Pick your character’s voice from our library of unique voices, or clone a voice of your own. Give every character a distinct voice and bring your world to life. When creating your initial scene, select or create objects and assign each one a sound from our sound library. The Orchestrator then intelligently deploys those sounds throughout the scene to make the experience feel completely immersive.

A personal touch

Or Clone Your Own Voice

It’s easy: record a short sample of your voice, and Kawabunga does the rest. Create your voice in minutes and use it for any character or experience.

Traceable knowledge

Transparent Sources

Our architecture lets users see every uploaded source and page, distinguishing primary and secondary sources, as well as synthetic material that users can use to change or create character personalities for fantasy worlds or other unique creations.

Creator control

Users Can Create More Accurate, Fully Curated Characters

Given our transparent sources architecture, users can trace each source and build fully curated, more accurate characters, such as real historical figures.

The Kawabunga Experience

Create a setting, step into history, begin with source material, or enter a story that keeps moving around you.

Source to Story

Start With Anything

Begin with an idea, book, document, or research. Kawabunga transforms your source material into characters, stories, and interactive experiences.

Character Design

Shape a Cast That Evolves

Define each character’s knowledge, goals, emotions, and relationships. They remember events, enter or leave scenes, and respond to one another in real time.

World Design

Create Any Setting

Build a fantasy kingdom, mystery, pirate ship, historical period, or universe of your own. Set its challenges, stakes, boundaries, and rules.

Persistent Worlds

A World That Remembers

Every action becomes part of the world’s history. Characters remember, relationships evolve, and future scenes respond to earlier choices.

Sound that responds

Adaptive Spatial Audio

We built adaptive spatial audio into our architecture, so you can hear characters become quieter as they move away, louder as they approach, and shift naturally through the world around you.

Scene atmosphere

Bring Your World to Life

Add sounds to your world and let Kawabunga trigger them naturally as the story unfolds.

Choose the kind of world

Education

The best way to learn is Socratically. Study for a test or step into history through conversation, like an audio time machine.

For Creators

Create Historically Grounded Characters

Upload and curate the sources that shape what a historical character knows, believes, and says. With carefully selected historical material, creators can build richly grounded figures—from Napoleon and Shakespeare to George Washington—then speak with them, question their ideas, and experience history in an entirely new way.
