Omi is a wearable AI pendant and smart glasses device developed by Based Hardware, a San Francisco-based open-source hardware company founded by Thiel Fellow Koky Shevchenko. The product positions itself as a “2nd brain” that captures your screen and conversations, transcribes them in real time, creates tasks, reminders, memories, and advice, and works across desktop, phone, and wearable form factors. Unlike most AI wearables that lock users into expensive subscriptions, Omi is built on fully open-source hardware and software, allowing users to self-host, use their own AI API keys, or route processing to a local LLM for complete privacy and cost control. The device is roughly the size of a coin, can be worn as a pendant, clipped to clothing, or attached to the forehead, and connects to a companion app available on iOS, Android, Mac, and web.
Omi Pendant (Consumer Version)
The flagship wearable AI device in a compact round orb form factor, available in multiple colors. Captures conversations, transcribes in real time across 25+ languages, creates tasks and memories, and offers a searchable “Brain Map.”
Omi Dev Kit 2
An earlier developer-focused hardware version available for approximately $70, designed for developers who want to build custom apps, connect their own AI models, or experiment with local processing. The fully open-source platform has already spawned 250+ developer-built apps.
Omi Glass Dev Kit
A smart glasses form factor currently in development, signaling Omi’s expansion beyond the pendant into augmented reality and ambient computing. Listed on the site as a separate product for early adopters and developers.
Omi Wrist Band
A wrist-worn accessory version of the Omi platform, extending the always-listening AI functionality to a wearable band form factor.
Omi Wireless Charger
A branded wireless charger accessory for the Omi pendant.
Omi App (Free, Mobile and Desktop)
A companion app available on iOS, Android, Mac, and web that serves as the hub for all Omi-captured data, including transcripts, memories, tasks, reminders, and third-party app integrations. Free to download and use.
Omi App Store (Thousands of Apps)
A curated marketplace of third-party apps built on the Omi platform covering productivity, relationships, health, companionship, sales, healthcare, and more, all accessible through the Omi device.
Omi’s core differentiator is its radical commitment to openness and user control in a market dominated by closed, subscription-heavy AI devices. Because the device is designed to offload processing to your own smartphone and potentially your own API keys, ongoing costs are controlled by the user, not the manufacturer. The hardware is fully open-source on GitHub, meaning developers can inspect, modify, and extend everything about how the device works, including routing all data to a local LLM for a truly private and free experience. At $89 with no mandatory subscription, Omi is strategically positioned to undercut major competitors like Limitless and Humane who charge $20 to $30 per month for cloud services on top of device costs. The companion app works across every major platform, and the growing library of 250+ developer-built apps means the device gets more capable over time without the user paying more. For privacy advocates, biohackers, and productivity professionals who want ambient AI without vendor lock-in, Omi represents a genuinely different approach.
