Build a rule from the details already on your Shopify products. Combine conditions, exclude what you don’t want, and see how many products match before you save.
- Tag, product type, vendor, collection, category or status
- Price, stock level and product title
- AND, OR and “is not”, in any combination
- Metafields and scanned trading cards too
PRIORITY & FALLBACK
A clear order, no surprises
Rules are checked top to bottom and the first match wins. Anything no rule catches gets your store’s default template.
Priority
Drag to reorder. Top match wins.
Your list order is the priority. A more specific rule beats the broader rule it refines, wherever it sits.
- Drag any rule up or down the list
- More specific rules win automatically
- Pause a rule without deleting it
- Limit a rule to a date range

Rules match on the product itself, so anything you add later that fits a rule is written in that rule’s template. Nothing to remember, nothing to pick.
- Every generation checks your current rules
- Works for one product or a whole bulk run
- See each product’s template before you generate
- Rules only choose the design. You decide when to generate.
DESIGNED TEMPLATES
Rules point at real designed templates
Every rule picks a designed template family, each with its own layout, type and brand art, or a template you built yourself in the editor.

The Template Editor is where you design your product description layouts. You build sections and elements visually, and the AI writes into the right slots, so every product gets a consistent, designed description that's written specifically for that product.
Descriptions are written by the MerchUp AI Engine from your real product data (titles, variants, options and tags) into your designed template, so it doesn't invent specifications or prices, and structured facts like pricing stay locked. Choose a writing quality level (Standard, Polished or Premium), and review or edit everything before it's published.
Yes. The Template Editor gives you full visual control — start from one of our professionally designed template families or build your own layout with sections, elements, backgrounds, effects, and typography controls. Every part of a template can be restyled to match your brand, no code required.
Yes — MerchUp includes a library of professionally designed template families, each a genuinely distinct design system with its own layouts, typography, and artwork. Five families are free and included on every plan, and the rest can be bought individually at any time — there is no plan restriction on which ready-made templates you can use. Separately, your plan sets how many custom templates you can build and save in the Template Editor: Starter 1, Growth 5, Pro and Scale unlimited. That allowance applies only to templates you create yourself — it never limits the ready-made families available to you.
Descriptions are published to Shopify by MerchUp, so your storefront always reflects what you generated and approved. When you update a template, descriptions generated or regenerated from that point use the updated design — you stay in control of what gets pushed to your store.
You don't need to write CSS — the Template Editor exposes deep visual styling controls (layout, spacing, typography, colours, backgrounds, and effects) on every plan. The styling is baked into each description when it's published, so your designs render faithfully inside your Shopify theme.
