Why Hivemind?
When building fictional worlds — whether you're writing a novel, designing a game, or running an RPG campaign — AI tools can be powerful collaborators. But they hallucinate. Ask your AI assistant about a character you created last week, and it might invent details that contradict your established canon.
Hivemind solves this by giving AI tools structured access to your Obsidian vault. Think of it as an AI Firewall: your worldbuilding notes become a truth anchor that keeps AI grounded in facts you control. Ask about a character, and the AI reads your actual notes — not a hallucinated version. Query a timeline, and it references your established events — not invented dates.
Beyond AI integration, Hivemind provides powerful visualization tools:
Timeline View — See your story's events laid out chronologically
Graph View — Explore relationships between characters, locations, factions, and more
Canon Workflow — Track which content is approved, in review, or still draft
Hivemind is built for worldbuilders, but the same principles apply to research vaults, people management, software architecture — anywhere you need AI to respect your established knowledge.
