The Problem

Vercel AI SDK is stateless by design. Each request starts fresh. Your AI features don't remember users, don't persist context, and can't prove what they knew.

Step 1

Connect

→

Step 2

Ingest + Extract

→

Step 3

Verify + Receipt

The Fix

npm install @verifiedstate/vercel-ai

Beta: tagging-level integration. Ingestion works via @verifiedstate/sdk with Vercel AI SDK-specific source tagging. Native Vercel AI SDK features coming.

typescriptBeta
import { verifiedMemory } from '@verifiedstate/vercel-ai';

const memory = verifiedMemory({
  apiKey: 'vs_live_...',
  namespaceId: 'webapp',
});
