Goyal’s Temple: ‘Humanity’s last personal device’

By · Published by Everything Blog

In short

The Temple 01 wearable attaches directly to the user's temple using medical-grade adhesive tape and features week-long battery life without screens or cameras. Motion sensors detect voice vibrations to transcribe audio into text, completely avoiding ambient sound capture. Users operate the system by double tapping, accompanied by haptic feedback, to log notes, send messages, and set reminders securely. Placed near the superficial temporal artery, the device tracks heart rate, sleep, VO2 max, and is being developed to monitor core temperature and chewing.

Temple 01 is expected to begin shipping in early 2027 with AI and health-tracking features.

Announcing the device on X on Friday, Goyal said Temple emerged from a health wearable project he had been developing as a weekend experiment while he was still leading Eternal. An engineering breakthrough during the project prompted him to return to building full-time and launch Temple, he claimed.

The device uses motion sensors to detect vibrations generated by the wearer's voice and convert them into text, eliminating the need for a conventional microphone. Goyal has described the technology as the world's first “roomdeaf” voice AI companion, saying it can distinguish the wearer's voice from surrounding conversations and noise.

No microphone, no camera: How Temple works

Temple is designed to attach to the wearer's temple using medical-grade adhesive tapes called Grips. It has no microphone, camera or screen and is activated through a double tap. A small vibration confirms when it starts listening, while another signals when the interaction is complete.Goyal said the device is designed for continuous, multi-day…
