In your hands
Your library.Your choices. 01 Bring what you’ve made. Import supported characters, lorebooks, personas, and presets. Check what a conversion keeps before you export.
Import your first piece ↗ 02 Choose who you write with. Connect your own AI provider. Provider access and usage costs are separate from Bunzai.
Set up the studio ↗ 03 Keep your work close. Your library is stored locally and encrypted at rest. Selected content is sent to the AI provider and connected services you use.
How local storage works Key protection depends on your setup. Some fallback configurations store a key file beside the library. Bunzai has no account or telemetry service.
Your first scene
A place to begin. Set up the studio, bring in a character, and choose a connection.
