Your Vault. Verified.

Obsidian stores your knowledge. VerifiedState verifies it and makes it queryable by AI agents.

The Problem

Obsidian is where you think. 300M+ downloads. Massive plugin ecosystem. But your AI agents can't access your vault. Even if they could, they'd treat notes as raw text — no structure, no verification, no temporal queries like "what did I believe about X in January?"

Your vault becomes queryable by any AI agent.

Receipt: rct_8b2c · source: obsidian_bridge

Your notes. Verified. Queryable everywhere.

The Fix

npm install @verifiedstate/obsidian

typescript
import { ObsidianBridge } from '@verifiedstate/obsidian';

const bridge = new ObsidianBridge({
  apiKey: 'vs_live_...',
  vaultPath: '/path/to/vault',
  namespaceId: 'my_knowledge',
});

// Watch for changes, extract assertions, verify automatically
await bridge.start();

// Your notes are now verified, structured, and queryable
// by any AI agent via the VerifiedState API or MCP server
// Frontmatter, wikilinks, and tags are all preserved

FAQ

Does it move my notes out of Obsidian?

No. The bridge reads your vault and syncs assertions to VerifiedState. Your vault stays local and untouched.

What gets extracted?

Frontmatter fields, wikilinks, tags, and content assertions. Each note can produce multiple verified assertions.

Can I query my vault from other AI agents?

Yes. Once synced, any MCP-compatible agent or API client can query your knowledge.
