Cog

A plain-text memory system for AI agents

Cog stores preferences, project context, and long-term goals in plain-text files shared across Claude Code, Codex, Cursor, Gemini CLI, Windsurf, Copilot, Opencode, Cowork, and other agents. An optional pipeline can run on a schedule to archive stale data, consolidate patterns, audit the architecture, and surface strategic nudges.
