Wax vs brain-mcp

Wax: Wax provides persistent, searchable, and private on-device memory for iOS and macOS AI agents, eliminating the need for servers or cloud services. It integrates document storage, semantic search (HNSW), full-text search (BM25), and token budgeting into a single, crash-safe .wax file.; brain-mcp: Brain-mcp is a local-first AI memory system that allows users to search, synthesize, and reconstruct their cognitive state from thousands of past AI conversations. It addresses the problem of losing valuable insights and context accumulated across various AI assistants, providing an external 'hard drive' for your thought processes.
