Covalence is a macOS application that provides persistent memory across different AI clients (Claude, Cursor, and MCP) by maintaining a local SQLite database with embeddings and search capabilities. It's interesting because it enables continuity in AI-assisted workflows while maintaining complete privacy through fully local, on-device processing without cloud dependencies.

Target audience: developers, technical writers, researchers using AI coding assistants
