dense-mem vs celiums-memory

dense-mem: Dense-Mem is a self-hosted, durable memory layer for AI agents designed to preserve evidence, detect conflicts, and prevent silent rewriting of facts. It provides typed claims, verification gates, server-side embeddings, and structured recall, enabling host LLMs to focus on conversation and judgment while Dense-Mem manages memory state.; celiums-memory: Celiums Memory is a cognitive memory engine designed to be embedded within other software like agents and assistants, providing persistent memory, journaling, and an auditable ethics engine. It speaks the Model Context Protocol (MCP) to offer these advanced cognitive capabilities without requiring developers to build them from scratch.

Features

dense-mem logodense-mem
01First-class evidence provenance, tracing memories from source fragments to facts.
02Facts pass through typed claims, verification, and promotion gates.
03Explicit conflict detection where comparable conflicts return clarification tasks, preventing silent overwrites.
04Clear responsibility boundary: host LLM judges, Dense-Mem manages durable state, gates, and audit metadata.
05Self-hosted with operator control over storage, team isolation, API keys, and data egress boundaries.
celiums-memory logoceliums-memory
01Cognitive Memory with Hybrid Retrieval (vector + full-text + affective/PAD resonance)
02Append-Only Hash-Chained First-Person Agent Journal
03Auditable 4-Layer Ethics Engine for moral evaluation
04Per-User Biological Clock modulating arousal and recall
05Flexible Storage Adapters (SQLite for local/embedded, Postgres+Qdrant+Valkey for clustered)
