Who this article is for: Merchants using Plug in AI whose products have no category set.
What you'll learn: Why the category matters for AI shopping agents, and how to get a suggestion and apply it.
Shopify syncs products to AI shopping agents by category. A product with no category doesn't get synced properly, which is why the app flags it as an agent readiness issue.
You don't have to work the category out yourself. The app suggests one, you review it, and apply it.
1. Open the product and find "Suggested category"
It's in the right-hand column of the product page, just below Agent readiness issues.
2. Click "Suggest a category"
3. Pick the one that fits
You'll get category paths to choose from, for example Sporting Goods > Outdoor Recreation > Winter Sports & Activities. Select the one that describes your product best.
4. Click "Apply category"
The button stays greyed out until you've selected one.
If none of them fit: Click "Suggest again" for a fresh set of suggestions.
If the suggestions still don't match, set the category yourself on the product's page in your Shopify admin. The app reads it from there either way — what matters is that the product has a category, not where you set it.
