When to use
Optimised for: always-on capture + lifelog timeline + voice UX
Anti-fit: not for enterprise compliance-regulated environments without explicit consent flows
Pros & cons
Pros
Local-first lifelog architecture (originated as Rewind) is privacy-stronger than competitors; Meta acquisition gives it deep funding.
Cons
Recent platform pivot from Rewind macOS; product direction post-acquisition uncertain.
Claims & capabilities
Rebranded from Rewind (April 2024). Acquired by Meta December 2025.

Similar systems
Other voice-first / wearable ai memory in the catalog, ranked by inbound references.
- Granola T1
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.
- Bee T1
Acquired by Amazon (Jul 2025); bee.computer is now © Amazon and sells the Bee Frontier wearable ($74.99), with a Bee Eclipse device marked coming soon. 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.
- Era Computer T5
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 from 14+ providers. Founded 2025 by ex-Humane team.
- Friend T1
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.
- Memories.ai LVMM 2.0 / Project LUCI T2
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/experiences. Hardware-level security via Qualcomm partnership; cloud sync for enterprise tiers.
- Omi T1
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-256), full local/self-hosted available under MIT.
