HippocampAI
Enterprise Memory Engine for Intelligent AI Systems
HippocampAI is a production-ready, open-source memory engine that transforms how AI systems remember, reason, and learn from interactions. It provides persistent, intelligent memory capabilities with 102+ API methods covering knowledge graphs, hybrid retrieval, multi-agent collaboration, and more.
Named after the hippocampus — the brain region responsible for memory formation — it gives AI systems human-like memory capabilities: storing preferences, tracking facts, detecting behavioral patterns, and delivering personalized experiences across sessions.
Current Release: v0.5.0
Knowledge graph, graph-aware retrieval, feedback loops, triggers, procedural memory, and embedding migration.
Key Features
Knowledge Graph
Real-time entity & relationship extraction on every remember() call. Graph-aware retrieval with 3-way RRF fusion.
Hybrid Retrieval
Vector similarity + BM25 keyword + graph traversal combined via Reciprocal Rank Fusion for 40% better accuracy.
Multi-Agent Collaboration
Shared memory spaces for agent coordination. Multiple agents can remember and recall from collective knowledge.
Sleep Phase Consolidation
Bio-inspired memory consolidation: merge related memories, decay importance scores, prune low-value data.
Memory Triggers
Event-driven webhooks, websocket, and log actions that fire on memory creation, updates, or retrieval.
Procedural Memory
Self-optimizing prompts via learned behavioral rules. AI learns to communicate better over time.
Predictive Analytics
Pattern detection, habit tracking, and behavioral insights with cross-session temporal reasoning.
Auto-Healing
Automatic detection and repair of memory issues. Health monitoring and quality tracking built in.
Plugin System
Custom processors, scorers, retrievers, and filters. Custom schemas, tiered storage, export/import.
SaaS Platform
Full multi-tenant platform with auth, rate limiting, Celery background tasks, and React dashboard.
Architecture Overview
HippocampAI follows a pipeline architecture with knowledge graph integration:
Package Structure
HippocampAI is organized into two packages for flexibility:
- hippocampai.core — Core memory engine (lightweight, no SaaS deps). For library integration and embedded use.
- hippocampai.platform — SaaS platform (API, auth, Celery, monitoring). For self-hosted SaaS deployment.
