A browser service is convenient, but it normally places the provider between the user and every task. Installable software makes a different architecture possible.
The device becomes the default boundary
Local models can process prompts and files where they already live. After the model is downloaded, supported workflows can continue without a network connection.
Hardware becomes a product choice
Local performance depends on the selected model and device. That constraint should be visible. A useful free model provides a real starting point, while Pro can add larger models or broader choice.
Cloud remains a choice, not a hidden requirement
Where an app supports a third-party cloud model, the user can choose that path for its capabilities. The interface should make the changed boundary clear before use.
