Voice-first / wearable AI memory

11 systems in the voice-first / wearable ai memory category of the AI Agent Infrastructure Landscape, grouped by maturity tier.

Tier 1 — battle-tested (8)

  • Bee Audio pendant — never stores raw audio

    Small wearable (pendant / clip / bracelet). Continuous capture; converts speech to text immediately; never stores raw audio . Daily summaries, personal fact sheet, to-do suggestions. Cloud processing on derived text only.

Tier 2 — production-ready (2)

  • Memories.ai LVMM 2.0 / Project LUCI On-device Large Visual Memory Model for wearables

    Developer-first reference platform for AI wearables. LVMM 2.0 captures visual data through video, encodes it into frames on-device, and stores moments as searchable memories; companion app surfaces past conversations/decisions/experience…

  • Sandbar Stream Smart ring + voice-activated capture

    Smart ring with voice-activated capture (tap to record, not always-on). Personal knowledge graph with companies, people, meetings; pulls context from past meetings and shared interests. Ex-Meta engineering team.

Tier 5 — theoretical / informal (1)

  • Era Computer User-sovereign pluggable memory layer for wearable OS

    Software platform / OS layer for AI wearables (glasses, rings, pendants, speakers) that abstracts hardware from AI orchestration. Memory and model providers are pluggable and user-controlled rather than cloud-locked; supports 130+ LLMs f…
