The Model Is Not the Product: A Dual-Pillar Architecture for Local-First Psychological Coaching
The paper introduces Psych LM, an iOS application designed for psychological coaching using a local-first architecture. This system aims to provide persistent context and emotional support through an innovative memory corpus. The research emphasizes the importance of architectural control in achieving reliable, context-aware interactions in mobile environments.
- ▪Psych LM runs a local, on-device language model for behavioral and life-coaching applications.
- ▪The system features an automated memory corpus that converts conversations into structured memory cards.
- ▪It prioritizes privacy and architectural control over simple model size to enhance user interaction.
