altk-evolve vs ctx-open

altk-evolve: Evolve is a system designed to help agents improve over time by learning from their trajectories. It uses an MCP server for tool integration, vector storage for memory, and LLM-based conflict resolution to refine its knowledge base.; ctx-open: 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.
