Open Zk Kb

Open Zk Kb is an open-source personal and agent memory system that provides AI agents with persistent, local, human-readable memory and knowledge management. It lets agents (and users) store preferences, corrections, and context across sessions, with hybrid semantic search, atomic notes in Markdown (Zettelkasten style), and support for multiple clients like Claude, Cursor, OpenCode, Zed, Pi, and more. The system runs fully locally, requires no cloud or API key, and enables context-sharing across agents and tools for reliable, cumulative learning.
