The AI Assistant That Never Spies on You

Hustler Words – Silicon Valley is witnessing the rise of a new kind of artificial intelligence—one that refuses to trade your personal secrets for profit. Sigil Wen, a self-taught coding prodigy who cut his teeth in elite AI hacker houses alongside industry titans like Andrej Karpathy and the founders of Perplexity, has officially unveiled Underdog. This invite-only beta represents a radical departure from the current AI landscape, prioritizing absolute user privacy through local, on-device processing.

Unlike the massive, data-hungry models hosted in remote cloud data centers, Underdog lives entirely on your hardware. Currently available for Mac and Windows users—with mobile and Linux versions on the horizon—the assistant utilizes Wen’s proprietary "Husky" inference engine. This specialized software is engineered for high-speed performance by minimizing the data movement between a computer’s central processor and its graphics chip, a common bottleneck in local AI execution.

While Underdog utilizes a more compact 27-billion parameter model fine-tuned from Qwen3.8 27B, Wen argues that performance does not have to suffer for the sake of security. In fact, the model reportedly rivals the benchmarks set by Claude Opus 4.6 just months ago, making it more than capable of managing daily complexities like financial research or academic assistance.

The most disruptive element of Underdog, however, is its economic architecture. Most AI giants rely on harvesting user data to fuel advertising engines or train future models. Underdog breaks this cycle by adopting a fintech-inspired revenue model. Backed by Stripe co-founder Patrick Collison, the startup, Conway Research, plans to forgo subscriptions and ads. Instead, it will take a microscopic transaction fee when the AI facilitates a purchase via secure payment rails. This ensures the company’s interests remain aligned with the user, much like a traditional banking institution.

The pedigree of Conway Research is nothing short of stellar. Beyond Collison, the venture has secured backing from heavyweights including Andreessen Horowitz, Khosla Ventures, and SV Angel. The investor list reads like a "who’s who" of the tech world, featuring names like Guillermo Rauch and Noam Brown.

As Wen puts it in his recent manifesto, the era of surrendering intimate medical, financial, and personal data just to use a helpful tool must end. For Wen, Underdog isn’t just a business venture; it is a product he intends to be proud enough to let his own children use. In a world of digital surveillance, Underdog is positioning itself as the first true ally in your pocket.
