CTX is a cognitive version control system for AI agents, preserving structured reasoning artifacts as durable state instead of ephemeral chat transcripts. It enables agents to maintain continuity across sessions, track decisions, and reproduce reasoning paths. The system includes a CLI, a local MCP server, and a web viewer.

CTX is the standard Cognitive Version Control System for AI. Structured working memory for AI agents. CTX preserves goals, tasks, evidence, decisions, conclusions, runbooks, and origins so agents can continue work instead of restarting from scratch.
