AI agents need more than conversation history to avoid repeating mistakes. This guide compares five memory systems: Hindsight for retention, recall, and reflection; Mem0 for application-integrated memory; Graphiti for temporal knowledge graphs; Letta for persistent, stateful agents; and Cognee for configurable graph-oriented pipelines. Learn how to test cross-session recall, project-level isolation, memory updates, deletion, and resistance to malicious instructions before choosing an architecture.
