The Assistant you actually own.
Modular. Private. Open.
A composable agent system that you own and control. Speak or type to automate your daily workflows. By default every app, model execution, and learning loop runs 100% locally.

Ship nothing to the cloud.
Develop web Zeug, plug it into hirn's ecosystem, and forget about everything else. No servers, no deployment pipelines, no cloud bills.
Zero infrastructure
No servers to run
Zeug runs on the user's device. No backend to operate, no database to secure, no rate limits to manage.
Custom interface
Your own UI
Ship a full HTML and JS interface that opens inside hirn using a bidirectional, real-time, fully offline SDK.
Ecosystem
Plug in, not build out
Focus on what your skill actually does. Deployment, security, and data infrastructure are not a worry.
Everything stays on your local hardware. No corporate telemetry, no data collection, no exceptions. Not now, not ever. Your data, your models, your decisions.
