Deployment

Omi, by Based Hardware (founder and CEO Nik Shevchenko, a Thiel Fellow, in San Francisco, with about $700,000 raised), is a shipping AI necklace in the ambient-recording 'second brain' category: a small circular orb worn on a neck lanyard that captures conversations and runs them through GPT-4o for ambient transcription in more than 25 languages, auto-summaries and tasks, a searchable memory database, daily recaps, and a Brain Map. It sells for $89 as a consumer unit or about $70 as a dev unit, with a free tier of unlimited on-device transcription plus 1,200 cloud minutes a month and an Omi Unlimited plan from $16 a month, on a hardware-sale-plus-subscription model where the user owns the device. It is one of the few genuinely open-hardware entries in the cohort, with an MIT-licensed GitHub repository of around 12,700 stars containing firmware, mobile and desktop apps, a backend, and open hardware designs, actively maintained into 2026. A disambiguation worth recording: Omi is distinct from Friend, Avi Schiffmann's AI companion pendant already in the registry, since Shevchenko's device was originally also called Friend and was renamed Omi after Schiffmann's competing device acquired the friend.com domain. The AI is genuine cloud functionality rather than veneer. A significant cap-flag applies to the aspirational marketing: CES 2025 headlines describing a brain interface that reads your mind via neural signal are unverified, with TechCrunch explicitly unable to verify the brain interface, the shipping product being audio-only, and the brain-computer-interface module remaining a 2026-2027 roadmap item with no EEG implementation in the open repository, so all neural and mind-reading claims are treated as aspirational.
