Cortex Overview

Cortex provides a local persistent memory system for AI coding agents such as Codex, Gemini CLI, and Claude Code. It implements 36 computational neuroscience mechanisms to consolidate, update, and retrieve relevant context dynamically as projects evolve. It supports both SQLite (default, zero setup) and PostgreSQL with pgvector for larger or shared databases. Cortex integrates with Claude Code via a plugin that adds automatic lifecycle hooks, while other hosts can use its memory through explicit tool calls.
