Button Computer makes a wearable button that activates voice AI on demand. When pressed, it captures audio via a dual‑mic array, sends the query over Bluetooth to a paired phone for processing by cloud language models, and plays the response through a built‑in speaker, with all‑day battery life and privacy‑by‑design (no passive listening). The device is sold for $179 with an optional $7.99 / month subscription for managed API access or a BYOK option for custom endpoints.

Problem
Accessing generative AI on a smartphone requires multiple steps—unlocking the device, launching an app, and waiting for a response—introducing latency and friction that discourages frequent use. Additionally, many voice‑activated wearables continuously listen, raising privacy concerns for users who want on‑demand assistance without constant audio monitoring.
Solution
Button Computer delivers a wearable hardware button that provides instant, on‑demand voice AI interactions. The device activates only when the user presses the physical button, ensuring that audio capture occurs solely on request. A dual‑mic array and integrated speaker deliver high‑fidelity capture and playback, while Bluetooth connectivity routes queries to cloud‑based language models via the paired phone. All‑day battery life and a detachable clip or magnetic mount let users keep the device accessible in any context. Privacy is enforced by design: the system does not listen passively and stores no conversation data locally. Users can subscribe to Button AI Pro for managed API access or supply their own API key for a self‑service model. The solution integrates with iOS at launch, with Android support planned for a future release.
