# Aria — the companion

> A consumer health companion built on Carry: it only remembers what you allow, and proves it on every reply.

**Aria** is the human face of Carry — a health companion that only recalls what you've authorized, and proves it live. It runs on the exact same engine as everything else: the same gate, the same Answer Receipt, the same on-chain proofs.

  carrysui.vercel.app/companion — the live companion.
</Card>

## Why it exists

An access matrix is abstract. A person who asks *"am I allergic to anything?"*, gets a caring answer, then **watches the vault lock** when they revoke access — that's the moment Carry's whole thesis becomes something you feel.

## The screen

Aria is a two-column console:

<CardGroup cols={2}>
  <Card title="The conversation" icon="comments">
    Ask Aria anything. Every answer drops an Answer Receipt beneath it — the memory used, verified on Walrus, with an **Anchor on Sui** action.
  </Card>

  <Card title="The live vault rail" icon="database">
    A **Memory Vault** (each blob, its Walrus status), the **Access Gate** toggle, and a streaming **Gate Log** that shows the retrieval decision as it happens.
  </Card>
</CardGroup>

## The moment

<Steps>
  <Step title="It knows you">
    Ask *"Am I allergic to anything?"* → Aria answers from your `health` vault; the receipt shows `verified ✓ on Walrus`.
  </Step>

  <Step title="Revoke">
    Flip the **Health Vault** toggle. The vault cards lock red; the gate log streams `policy … → revoke`.
  </Step>

  <Step title="Proof of the block">
    Ask the same question again. Aria truthfully can't see it — the receipt turns red: `health — never fetched, the gate ran before Aria saw it`. Your most sensitive data never reached the model.
  </Step>

  <Step title="Anchor + verify">
    Hit **Anchor on Sui** under any receipt → a real transaction mints a proof object and hands back a `verify` link. Open it: three green checks, no wallet.
  </Step>
</Steps>

<Note>
  Aria runs on Anthropic **Claude** with a warm, health-companion persona, over the same gated vault the CLI and MCP server use. One vault, every surface.
