Deep Dive
Epitome runs on your own PostgreSQL instance with full schema isolation per user. Mem0 is a managed cloud service where your memory data lives on their infrastructure. With Epitome, you own your data pipeline end-to-end.
Epitome builds a structured knowledge graph with typed entities, weighted relationships, and recursive traversal. Mem0 stores memories as flat key-value pairs with basic tagging. The graph lets agents reason about connections between people, places, and concepts.
Every memory in Epitome has a confidence score that increases through reinforcement and decays over time. Mem0 memories are either stored or deleted. Confidence scoring means agents naturally prioritize trustworthy information.
