Runtime
The local process that runs speech models and exposes the voice workflow boundary.
Product
Izwi is the layer between raw speech models and the applications that need them. Use the desktop app to evaluate, the API to integrate, and Enterprise Runtime when deployment boundaries become operational requirements.

Product surfaces
Desktop helps teams explore. Server gives applications an API boundary. Enterprise Runtime supports controlled production deployment.
The local process that runs speech models and exposes the voice workflow boundary.
A familiar /v1 shape for applications that already use modern AI client patterns.
A native evaluation surface for testing models, audio files, and speech workflows.
A practical control surface for models, services, and local developer workflows.
Supported packaging, rollout guidance, and operational controls for production environments.
Runtime boundary
Izwi sits close to the application and data boundary, where speech workflows can be controlled and deployed deliberately.

API
Use a local host, a familiar client shape, and a private runtime boundary.
Applications can keep a familiar integration pattern while the runtime moves closer to the data. Izwi keeps the external shape familiar and changes the deployment boundary underneath.

Izwi stays focused on runtime infrastructure, so teams know exactly where it fits.
Start with docs if you are integrating. Start with sales if the deployment boundary is already real.
