Second Brain — AI memory assistant that models the three-layer human memory system (iOS)

Just launched on the App Store. It's a memory app where AI classifies your inputs into instant/short-term/long-term memories, builds connections between them, and helps you recall by meaning.

Key features:

• Text + voice capture with AI classification and tagging
• Semantic search (ask questions in natural language)
• People cards (track what everyone said/promised)
• Weekly AI reflections (finds patterns in your thinking)
• Memory connection graph
• Ebbinghaus forgetting curve visualization

Tech: SwiftUI, on-device classification (Apple NLP), Claude Haiku for search, Claude Sonnet for reflections (Pro).

Free with limits, Pro $4.99/month.
