About

Nosy is a pioneering project at the intersection of biology, technology, and community science.

We are on a mission to build the world’s largest open database of smells by equipping users with an innovative, handheld scent-sampling device. Using a cutting-edge sensor chip and secure cryptographic validation, the device allows anyone to collect and submit scent signatures from the world around them—capturing the hidden layer of reality that scent represents.

Whether you’re a curious technophile, a purpose-driven citizen, an artist, or a researcher, Nosy invites you to participate in this sensory revolution.

But we’re not just building hardware—we’re building a movement.

Each scent sample contributes to our growing, decentralized scent map, a living atlas of molecular experiences. Contributors are rewarded with Web3 incentives that drive participation, data quality, and innovation. Our vision is bold and grounded: by understanding the invisible world of scent, we can unlock breakthroughs in health, safety, emotional memory, AI, and the environment.

At Nosy, we believe smell is not just a sense—it’s a signal. And it’s time to start listening.
