Subtle isolates clear voice in any background environment, and at any volume.

Private

Speak softly to friends or AI without being overheard, even in public.

Natural

Use voice to be more productive, yet more present than ever.

Hear the Difference

Compared to today’s top voice tech, Subtle is faster, clearer, and more accurate in real-world conditions. We train Subtle Voice™ models end-to-end and optimize for real-time processing on-device. The result is world-leading audio quality and reduced word error rates¹ by up to 10x in real-world settings.

OUR VISION

Do more without
looking down at a screen.

More Present

Computing has been trapped in the same paradigm for decades. Our devices force us to do every task click-by-click and letter-by-letter, all while staring at a screen. We believe a better computing experience should operate in the background, helping people become more capable and more grounded than ever.

More Productive

At its best, technology expands our abilities and unlocks entirely new experiences. We're leveraging our silent speech models to build a voice-first computing experience that breaks free of the endless doomscroll, letting us do more outside of apps while providing all the tools for immense productivity.

Subtle Computing

We are developing a new generation of subtle, powerful computing interfaces to help us access information with near-telepathic speed, while staying deeply present in the real world. We are currently testing prototypes in a private Beta (apply below).

JOIN THE BETA

We’re working on the next generation of intuitive voice-first interfaces.

Our first experience launches late 2025. Sign up to receive updates and apply to become a beta tester.
