Cortex – Agent-native knowledge OS on Markdown (Karpathy's LLM Wiki)

Cortex is an open-source, agent-native knowledge operating system that organizes information as a Markdown-based wiki, inspired by Andrej Karpathy's LLM Wiki concept. It is designed for developers and AI researchers who need a structured, LLM-friendly knowledge base that AI agents can autonomously read, write, and query. Its interesting because it bridges human-readable documentation with machine-interpretable data, enabling seamless collaboration between humans and AI agents on evolving knowledge.
