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.
- Friend Always-on AI companion pendant
Pendant necklace (~2 inches). Always-on listening feeds a persistent AI companion persona. Companionship-framed rather than productivity / recall. Cloud LLM backend; no detailed encryption claims.
- Granola Mac/iOS meeting notepad — system-audio tap
Mac/iOS app (no hardware). Captures meeting audio via system-audio tap (no bot joining); generates notes from your shorthand + audio. Local audio processing claim; cloud for summaries. Enterprise tier opts out of model training.
- Limitless Wearable pendant + screen capture lifelog
Continuously captures screen + audio + wearable input; AI search across the timeline. Privacy-first (local-first storage). Originated as Rewind macOS app; pivoted to wearable + lifelog product.
- Omi Open-source wearable orb + memory graph
Wearable orb (necklace or clip) with open-source hardware + firmware. Continuous audio capture; real-time GPT-4o transcription; searchable memory graph. Supports app screen capture too. Hybrid privacy: cloud by default (SOC 2/HIPAA/AES-2…
- Otter.ai Meeting bot + browser extension + app
Joins Zoom / Meet / Teams as a meeting bot. Real-time transcription, speaker identification, searchable archive across past meetings. SSO + admin controls at Business tier.

- 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…
