Hivemind for Obsidian


Your canon is the source of truth. AI stays inside the lines.

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.

Features

- Timeline View — Visualize events chronologically with filtering and search
- Graph View — Explore entity relationships with interactive visualization
- AI Integration — MCP-compatible server for Claude, GitHub Copilot, and other AI tools
- Pluggable Templates — Built-in templates for worldbuilding, research, people management, and more
- Canon Workflow — Draft → Pending → Canon approval system with consistency validation
- Obsidian Native — Works with standard markdown, YAML frontmatter, and wikilinks
- Local-First — Your data stays on your machine

Quick Start

1. Choose a template — Open Hivemind settings in Obsidian and select a template (worldbuilding, research, etc.)

2. Create entities — Use Obsidian's note creation as usual. Add YAML frontmatter to define entity types:
``yaml
---
entity_type: character
canon_status: draft
---
`

3. Visualize — Open the Timeline view or Graph view from the ribbon icons

4. Connect to AI — Follow the MCP Setup Guide to let AI tools query your vault
