Zikkaron vs Cortex

Zikkaron: Zikkaron is a persistent memory engine for Claude Code, built on computational neuroscience principles. It remembers your work, decisions, and context across sessions, using techniques like thermodynamic decay, predictive coding, and hippocampal replay to intelligently retrieve and consolidate memories. It runs entirely locally with 26 subsystems and 24 MCP tools.; Cortex: Cortex is an MCP server that gives Claude Code persistent memory inspired by neuroscience. It automatically captures, consolidates, and surfaces relevant context, achieving state-of-the-art retrieval benchmarks across multiple datasets.
