Pebble Index 01 $99 2-Year Zero-Charge Whisper Ring, LivingAI AIBI 42g Pocket Pet & KEYi Loona 3D ToF Teardown
Eric Migicovsky's $99 Pebble Index 01 smart ring runs for 24 months without a charger via zero-leakage silver-oxide power gating and local Whisper STT, while LivingAI AIBI (42g) and KEYi Loona (5 TOPS BPU + 3D ToF) advance personal companion robotics.
⚡ Key Engineering & Supply-Chain Takeaways
- Pebble Index 01 ($99, 4.2g 316L steel) uses a physical liquid-silicone thumb switch (0.00 µA standby leakage) and a sealed silver-oxide cell to capture daily whispered notes for 2 full years without charging.
- Index 01's open-source companion app runs Whisper STT and local LLM intent routing on your phone (2.9% whisper WER at 35 dBA) with $0 subscription fees.
- LivingAI AIBI Pocket ($249, 42g) clips magnetically onto shirts with back-to-back optical pet pairing, while KEYi Loona ($449) pairs a 5-TOPS BPU and 3D ToF SLAM for 31.5ms visual tracking and autonomous self-docking.

Zero-Charge 2-Year Smart Rings & Pocket-to-Floor Companion Robots
Product disclosures from Core Devices (Pebble), LivingAI, and KEYi Tech highlight three distinctive personal AI hardware designs:
- Pebble Index 01 ($99, 4.2g): Engineered by Pebble founder Eric Migicovsky's Core Devices, this 316L stainless steel ring places a physical silicone button in series with a silver-oxide primary cell (
0.00 µAstandby draw,1.8mscold boot), delivering 2 full years of whispered voice notes processed by local open-source Whisper STT with zero charging and zero subscription fees. - LivingAI AIBI Pocket ($249, 42g) & KEYi Loona Petbot ($449, 1.1kg): While the 42g AIBI snaps magnetically onto your shirt collar and pairs optically back-to-back with friends' AIBIs, the floor-roaming KEYi Loona leverages a 5-TOPS BPU and 3D ToF depth camera for 31.5ms local visual tracking, GPT-4o games, and 96.5% reliable autonomous self-docking.
