What's SensAI Hack?

SensAI Hackathons give you early access to devkits, wearables, and expert-led courses.
Join our community and team up with top XR, AI, CV, and mobile developers in year-round online and in-person hackathons and events. We bring together leading engineers, researchers, and creators to collaborate, learn, and push the boundaries of wearable technologies—accelerating the future of immersive, intelligent experiences.

Explore

Navigating the rapidly evolving XR/AI tech stacks can be daunting. With new products, SDKs, and LLMs emerging constantly, the learning curve stays steep. But don’t worry—our live workshops will quickly get you up to speed on the latest developements, ensuring you’re hack-ready in no time.

Collaborate

It’s more than just connecting with other hackers from all around the world—it’s about complementing skillsets. That’s why we accept both teams as well as individual hackers. Get excited about unlocking synergies that drive the creation of groundbreaking XR & AI Apps.

Innovate

Participants will team up with enterprise product leads to understand specific use cases deeply, then sprint hand-in-hand with subject matter expert mentorship and support. The results of our hackathon will showcase the transformative potential of the latest XR and AI technologies.
