# Product data

> Connect product feeds so your assistant recommends from your live catalog, and manage feeds over time.

Product data is the catalog your assistant recommends from. You connect it as a **product feed** — a structured source such as a Google Shopping, XML, or CSV feed — or by connecting your **Shopify store**, whose catalog then syncs automatically. Either way, product data stays separate from your general [knowledge stores](/en/user-guide/knowledge/knowledge-stores), so catalog updates flow in without touching your policies, FAQs, or other knowledge.

<Note>
  Knowledge stores answer questions about your business. Product data answers "which product?" — it is what the assistant draws on to make recommendations.
</Note>

## How product data feeds recommendations

When a shopper describes what they're looking for, the assistant matches their intent against your connected product feeds and suggests the best fits. Because feeds reflect your live catalog, recommendations stay aligned with what's actually available — including titles, descriptions, and other attributes you provide.

## Connect a product feed

<Steps>
  <Step title="Open Product data">
    In the [homie platform](https://app.yourhomie.ai), go to **Product data**.
  </Step>

  <Step title="Add a product data source">
    Click **Create** and choose **Product data feed** in the **Add product data source** dialog. (If you sell on Shopify, choose **Shopify store** to connect your catalog through the Shopify integration instead.)
  </Step>

  <Step title="Connect the feed">
    Enter your feed URL (Google Shopping, XML, or CSV), connect it, match the feed fields to homie's product fields, and give the feed a clear name.
  </Step>

  <Step title="Review the connected products">
    After the feed is processed, confirm your products appear as expected so the assistant has an accurate catalog to recommend from.
  </Step>
</Steps>

<Check>
  Once a feed is connected and processed, the assistant can recommend those products in conversations and on product pages.

## Keep a feed up to date

homie keeps each feed in sync automatically on the interval you choose, so recommendations stay aligned with your catalog. Open a feed to change its name, field mapping, or sync interval, or to trigger an update yourself with **Refresh** (available again a few minutes after each run). Changing the field mapping re-imports the full feed.

<Tip>
  Keep your feed current. An assistant that recommends out-of-stock or discontinued products erodes shopper trust.
</Tip>

## Delete a feed

Deleting a feed removes its products from the assistant's recommendation pool.

<Warning>
  After you delete a feed, the assistant can no longer recommend those products. Make sure the catalog is covered by another feed if those products should still be recommendable.
</Warning>
