codesearch vs memem

codesearch: codesearch is a token-efficient MCP server for AI agents that enables local semantic code search. It integrates with OpenCode, Claude Code and other AI assistants to perform intelligent code searches with minimal token usage, all running locally with no external API calls.; memem: memem is a Claude Code plugin that gives persistent memory across sessions. It automatically extracts durable lessons from completed sessions, stores them as markdown in an Obsidian vault, and surfaces relevant ones as an Active Memory Slice. It is local-first with no cloud services.
