Wax vs Context-Engine

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.; Context-Engine: Context-Engine is an open-core, self-improving code search tool that integrates with AI coding assistants. It allows developers to search their codebase, get answers with citations, and enhances AI agents' ability to explore code using its MCP tools.
