How the site describes itself:
Zettelkern · knowledge that maintains itself
Zettelkern is the Quellkern method for living knowledge: plain-markdown wikis that LLM agents build, cross-reference, and keep current. Built on Karpathy's LLM Wiki pattern and the Open Knowledge Format. The manual and the starter kit are free; help migrating existing knowledge bases is not.
