PPIO Sandbox: Equip Personal Agent with a dedicated 'cloud computer'.

Personal Agent is user-centric and needs to support long-term operation and proactive advancement, therefore it must be equipped with a dedicated 'cloud computer'. Current mainstream solutions include local operation (involves security risks and offline issues) and cloud operation (self-built by large companies or third-party hosting). PPIO Sandbox provides a ready-to-use, secure isolation, supports long-term operation and large-scale users cloud execution environment as an API for developers to use, helping to develop Agents for scenarios such as personal office, research, and programming assistants.
