Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureCalcAI lets merchants create interactive calculators for any product page without writing code. Use the AI builder to describe what you need in plain English, or build manually with the visual editor. Create pricing calculators that update cart prices at checkout, estimation tools that help customers plan purchases, or product recommendation flows that guide buyers to the right option.
Plomly is the only Shopify app that combines a measurement calculator with an AI shopping assistant — built for stores selling tile, paint, flooring, wallpaper, concrete, fence, and materials sold by m² or ft². Customers describe their project — "I'm tiling a 5m² bathroom" — and Plomly reads YOUR catalog, recommends the right products with quantities, and builds the cart in one click. Most calculators are generic.

- Calculators update cart totals at checkout automatically
- Embed on any product page using a theme block in minutes
- Create estimation tools and product recommendation flows
- Calculator widget on product pages for area, volume, linear, or unit math
- AI chat answers customer questions about quantity in natural language
- Project planner suggests complementary products based on the primary item
- AI wizard reads the catalog and proposes a configuration per variant
