Synapse is a personal AI chat with a Neo4j knowledge graph for deep, persistent memory across therapy, coaching, and wellbeing personas.

How does Synapse handle long-term memory?

Via 'Sleep Cycle': ingests chats into graph, compiles key hubs (~30K tokens) with waterfill for instant retrieval, evolves with timestamps.

Will Synapse work for non-devs?

Yes—no config. Notion UI optional. But costs scale with usage; best for committed users.
