The idea
AI systems shouldn't guess at databases. Zyrn is an append-only fact log where agents talk in typed calls instead of SQL, corrections supersede rather than overwrite, and every fact carries mandatory provenance — who said it, when, on what basis. The knowledge base describes itself to the agent reading it.
What's built
A shipped, self-hostable server with a one-line install, 800+ tests, and throughput measured in thousands of facts per second. Compliance postures (data residency, deletion, audit) compose through the substrate instead of being bolted on.
Where it stands
Open source and live at zyrn.ai. If you're building agents that need to remember things correctly, start there.
