Underdog Launches as a Leading Privacy-Centric AI Assistant

Silicon Valley — Underdog, a new AI assistant by Sigil Wen, launched in an invite-only beta on October 6, 2026. This innovative product stands out by prioritizing user privacy through on-device processing, setting it apart from competitors like Instinct and Muse.

Underdog keeps user data on personal devices, including Macs and Windows PCs, with plans for Linux, iPhone, and Android versions in development. This approach enhances privacy and reduces data transfer between a computer’s main chip and its graphics chip, addressing common concerns with many AI tools today.

Privacy Features of Underdog

Underdog operates entirely on-device, meaning sensitive user data remains on the user’s hardware rather than being sent to cloud servers. This is a key difference from competitors like Instinct and Muse, which rely on cloud-based processing that may expose user data to threats. Wen’s approach utilizes a custom-built inference engine, Husky, allowing AI models to function efficiently without compromising security.

In contrast, Instinct and Muse have faced criticism for their data handling practices, often collecting user data to improve their services at the cost of privacy. Underdog addresses these issues by ensuring it does not need to collect personal data to operate effectively.

Another significant aspect of Underdog’s privacy features is its encryption protocols. Users’ keys for email and other accounts accessed by the assistant are encrypted, adding an extra layer of security. This contrasts sharply with the more traditional data handling of Instinct and Muse, which do not offer such strong encryption measures by default.

Moreover, Underdog employs a smaller yet efficient model — a 27-billion parameter reasoning model fine-tuned from Qwen3.8-27B. This model is optimized for everyday tasks like shopping assistance and homework help, demonstrating that privacy does not have to sacrifice functionality. Wen claims this model performs similarly to larger models like Claude Opus 4.6 in various benchmarks.
