PlugClaw functions as a self-contained workstation housed within a 15-gram USB-C stick. It features a MediaTek Helio G80 processor, up to 6 GB of RAM, and 128 GB of encrypted storage. When connected to a host device—be it a Mac, Windows PC, iPhone, or Android handset—the host serves strictly as a display and input interface. The AI agent, its credentials, and all active applications execute entirely within PlugClaw’s privacy-hardened operating system, PlugOS.

This architecture creates a physical security boundary, ensuring that autonomous agents cannot access the host device's local files, contacts, or system-level settings. The agent interacts with applications through a GUI-based framework, mimicking human input to perform tasks like file organization, message drafting, and multi-step workflows. For cloud-based tasks, the device utilizes a Trusted Execution Environment (TEE) to ensure that sensitive data remains encrypted even during remote processing.

Retailing from US$149, the hardware arrives without a mandatory subscription, allowing users to leverage pre-installed models or integrate their own via API keys. TrustKernel is also providing free confidential-model inference on its newly deployed server infrastructure to encourage secure, private AI adoption.
