codesearch vs memex

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.; memex: memex provides persistent memory for AI coding agents using atomic knowledge cards with bidirectional links. It stores insights from each session and recalls relevant cards before starting new tasks, enabling agents to build on previous knowledge. No vector database or embeddings needed—just markdown files.
