hmem vs Ombre-Brain

hmem: hmem is a memory system for AI agents that persists project context across sessions, devices, and AI providers. It uses a 5-level lazy loading architecture to minimize token usage while retaining full details. It supports auto-logging, background checkpoints, and cross-platform sync.; Ombre-Brain: Ombre Brain is a long-term emotional memory system for Claude. It tags memories using Russell's valence/arousal coordinates, stores them as Obsidian-compatible Markdown, connects via MCP, and implements a forgetting curve. It features natural decay and active surfacing of unresolved memories.
