persistent-ai-memory vs subcog

persistent-ai-memory: Persistent AI Memory is a sophisticated memory management system for AI assistants that provides intelligent memory extraction, storage, and retrieval across multiple platforms. It features OpenWebUI-native integration, semantic search, conversation tracking, and tool call logging. The system ensures multi-user isolation and supports various embedding providers.; subcog: Subcog is a persistent memory system for AI coding assistants that captures decisions, learnings, and context from coding sessions. It features a single-binary distribution, three-layer storage architecture (SQLite, FTS5, usearch HNSW), MCP server integration, and Claude Code hooks. It achieves high accuracy on factual recall benchmarks.
