The Technology Behind fitnai

fitnai Smart Glasses is engineered at the intersection of optics, AI, and wearable design. Every feature is built to enhance your movement — not interrupt it. Learn about our story →

First-Person POV Recording

An integrated 8MP camera captures 1200P video directly from your point of view. With EIS (Electronic Image Stabilization), footage stays smooth even during high-intensity movement like cycling, running, or hiking.

AI Visual Recognition

Point at anything — a landmark, a plant, a road sign — and ask fitnai's AI what it is. Powered by real-time visual intelligence, fitnai gives you instant answers without reaching for your phone.

AI Voice Assistant & Translation

Speak naturally to fitnai. Ask for directions, translate foreign signs, check the weather, or get information about what's in front of you — all hands-free, all in motion.

Open-Ear Audio

fitnai's directional open-ear speakers let you hear music, calls, and AI responses while keeping you fully aware of your surroundings. Designed for safety on the road and trail.

Lightweight Sport Design

At just 49.3g, fitnai is built for all-day active wear. Anti-slip nose pads, ergonomic temples, IP54 water resistance, and optional RX insert support make it as practical as it is powerful.
