Your library.
Your choices.

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.
