Deepinder Goyal unveils Temple, the screen-free AI wearable shipping in 2027 at Rs 85,000

Deepinder Goyal Introduces Temple as Privacy-First AI Wearable

Deepinder Goyal, founder of Temple and former Eternal CEO, has unveiled Temple, an AI wearable he describes as humanity's last personal device1

1

. The device represents a departure from conventional wearables by eliminating screens, microphones, and cameras entirely. Goyal announced the device on X on Friday, revealing that Temple emerged from a health wearable project he developed as a weekend experiment while leading Eternal. An engineering breakthrough during that project prompted him to return to building full-time and launch Temple1

The screen-free microphone-free AI wearable is designed to attach near the wearer's temple using medical-grade adhesive tapes called Grips1

1

. Pre-orders opened on November 1, with the price reportedly set at Rs 85,000, which includes lifetime software access and the Grips2

2

. Temple 01 is expected to begin shipping in early 2027 with AI and health-tracking features1

How Vibration-Based Listening Technology Works

Temple uses motion sensors to detect vibrations generated by the wearer's voice and convert them into text, eliminating the need for a conventional microphone1

1

. Goyal has described the technology as the world's first roomdeaf AI companion, saying it can distinguish the wearer's voice from surrounding conversations and noise1

1

. Unlike other devices that record conversations happening around them, it reads the voice vibrations to understand what the user is saying2

.

The device is activated through a double tap, with a small vibration confirming when it starts listening and another signaling when the interaction is complete1

. Goyal said the device is designed for continuous, multi-day wear, including during showers, swimming, workouts and sleep, and needs to be recharged approximately once a week1

Privacy-First Approach with End-to-End Encryption

The privacy proposition is central to the product. Goyal emphasized that the absence of a microphone means Temple cannot capture conversations happening around its wearer1

1

. He also said conversations would be protected with end-to-end encryption and would never reach an external model company, adding that even Temple's own team would be unable to read them1

. However, these privacy claims have not yet been independently verified2

.

The device is intended to let users record thoughts, set reminders, remember personal details, send messages and track everyday activities without reaching for their phones1

1

. Users could ask it to remember birthdays, medication schedules or details from conversations, or log meals, workouts and health-related observations1

1

. Goyal said Temple is being positioned as a companion rather than an assistant because it will focus on tasks suited to its screen-free form factor and will not handle activities such as shopping1

AI Companionship with Health Tracking Capabilities

Beyond AI interactions, Temple is being developed as a health monitoring wearable. Goyal said it already supports tracking metrics including heart rate, heart-rate variability (HRV), sleep tracking and VO2 max1

. The company is also working on additional capabilities, including automatic chewing detection for calorie tracking, snoring patterns, sleep positions, jaw-clenching detection, rapid eye movement (REM) tracking and continuous core body temperature monitoring1

Goyal said the device's position near the superficial temporal artery could allow it to capture health and wellness signals that conventional wrist and finger wearables may not be able to detect1

. He also referred to ongoing research and validation work, including a project called Entropy, without providing further details1

Medical Community Raises Concerns About Health Claims

Deepinder Goyal received backlash from doctors and the wider medical community over his wearable project Temple, which began as a health-tracking device and is now being expanded into an AI companion2

2

. Critics, including AIIMS Delhi radiologist Dr Suvrankar Datta and hepatologist Dr Cyriac Abby Philips, have questioned the scientific validation behind its health claims2

2

. Despite this criticism, Goyal has positioned Temple as a continuing research and development project rather than a finished consumer product, saying the device would keep evolving as new capabilities emerge1

1

. He stated that Temple 01, shipping early 2027 with both AI and health features, is just the start, adding that he was looking forward to what future iterations, including Temple 20, could become1
