nocturne_memory vs locus

nocturne_memory: Nocturne Memory is a persistent memory system for AI agents, designed to overcome AI amnesia by anchoring their "soul" to permanent storage. It enables LLMs to retain long-term knowledge, maintain identity, and evolve their understanding beyond single conversation contexts.; locus: Locus provides persistent project-aware memory for AI coding tools, using three memory layers: structural, semantic, and episodic. It works with any MCP-compatible client and offers 14 tools and 3 resources for exploring, searching, and managing memory. Carbon Copy enables passive conversation capture for later recall.

Features

nocturne_memory logonocturne_memory
01Long-Term Persistence: AI memories are no longer limited by token count or session boundaries, stored permanently on disk.
02Identity Anchoring: A priority-weighted system ensures AI consistently "recalls" core memories upon startup, reinforcing its identity.
03Associative Recall: Memories are interconnected via URI paths and aliases, forming a human-like associative network for flexible recall.
04Version Control: Automatic snapshots for every memory modification allow human owners to review changes and perform one-click rollbacks.
05Content-Path Separation: A unique architecture separates memory content from its access paths, enabling flexible aliases, versioning, and secure deletion.

0314 MCP tools for exploring, recalling, searching, remembering, and managing memory
04FTS5 full-text search across all memory layers and conversation events
