Omi

Omi is a necklace from Based Hardware, catalogued as Wearable AI pendant in the Wearable voice capture meta-category. Its primary job is wearable voice capture for builders who need an inspectable path rather than a sealed appliance. In practice it targets: BLE pendant ambient conversation capture; Realtime transcription, summaries, action items; and Plugin / persona ecosystem; mobile + desktop apps.

Openness is listed as firmware+hardware+app. Technology notes in this catalog point to: nRF Zephyr firmware on wearable; Flutter apps + FastAPI backend; and Phone/desktop as STT/LLM compute. Heavy models usually sit on a phone, SBC, or edge box; the device itself is the sensor, array, camera, brain, or actuator surface depending on class.

For an agentic operating system this is an observe path without typing twice: ambient or buttoned audio becomes private STT and ledger-ready context for cases and proposals. Catalog possibilities include Self-hosted memory / second brain without Limitless lock-in; Custom personas for domain workflows; and Audit and fork the whole stack.

Limit: No clear finished-product Amazon listing; buy via omi.me / specialty channels; Open pendant.
