On June 5, Jianan Technology unveiled its K2 AI glasses priced at RMB 2,350. Centered on an ultra-lightweight design, the full device weighs merely 25.8 grams.
According to Jianan Technology, to enable all-day wear for spectacle users, smart glasses need to weigh under 40 grams, ideally below 30 grams for the frame. At 25.8 grams, the K2 hits this benchmark, delivering a wearing experience comparable to regular prescription eyewear.

AI Message Digest & Quick Note Functions
The AI Message Digest analyzes incoming notifications and generates optimized reply suggestions automatically. The AI Quick Note lets users capture key moments and information by long-pressing the right temple without taking out their phone, acting as a personal digital assistant.
The gadget also supports music playback and first-person video recording. Its audio delivers ambient immersive sound, while the camera enables instant first-person footage sharing.

No Redundant Status Alerts or Physical Buttons
Unnecessary status notifications and physical buttons have been eliminated on the K2. The device stays inconspicuous like ordinary glasses until manually activated. All interactions rely on tap and long-press controls on the temple, embodying the design philosophy of human-centric tech that fades into daily use.
Software Ecosystem
Features including AI Message Digest, Quick Note and AI assistant will roll out progressively as users wear the device. Starting this September, Jianan will open its AI application ecosystem and SDK for developers to build third-party applications.
