Close the laptop. It keeps writing.
A bulk run lives on our servers, not in your browser. Walk away and it finishes anyway. Stop it whenever you like and pay only for what was written.
- Keeps going if you close the tab
- Come back to the live progress
- Billed as each one lands, nothing prepaid
- Cancel any time, the rest is never billed
AFTER THE RUN
Your final say on every word
A bulk run never publishes on its own. Check each product, push what you want, and roll back anything later.
Review updates
Nothing goes live until you push it.
Each finished product lands in Review updates with its description and SEO. Compare it with what is live, keep what you want, then push.
- Every run lands in Review first
- SEO title, meta description and image alt text included
- Compare the new copy with what is live
- Push one, a few or all, now or on a schedule

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.
