Shopify apps for every step of the sale.

BundleUp for the product page, Vouch for the questions before buying, Cartify for the cart and ExtraSale for the thank-you page. AI is built into how they work, from designing a cart in one sentence to answering shoppers.

149 reviews on the Shopify App Store, every one five stars

A product page on a phone with the BundleUp widget: 1, 2 and 3 bottle tiers with the 2-pack marked Most popular.
Cartify cart drawer on a phone: gift unlocked on the reward bar, a free sneaker cleaner in the cart and a "Complete the look" upsell.
The Vouch review widget on a phone: star summary, a Write a review button and review cards with customer photos.
ExtraSale offer card on the Shopify thank-you page: a back massager at a discounted price with accept and No thanks buttons and a countdown.

Four moments decide a sale. We built an app for each.

A shopper looks at the product, wonders if it's right, opens the cart and checks out. Each app owns one of those moments, and they work on their own or together.

Set up an offer or a cart by describing it.

In BundleUp and Cartify you describe what you want, or paste a screenshot of a design you like. The AI builds it in a live preview with your real products, and nothing reaches your store until you press Save.

  1. 1. Describe it

    Type the change in plain words, or paste a screenshot of a design you like.

  2. 2. Watch it build

    The AI edits the real cart with your products, and the preview updates after every step.

  3. 3. Save when it's right

    Undo any AI change in one click. Nothing reaches the store until you press Save.

Cartify Cart designer reply "Done. The checkout button is now green" with the preview showing a green Check out securely button.

Where the AI helps

  • BundleUp and Cartify

    Type the offer or the cart you want. The AI builds it with your real products, prices and currency, in a live preview.

    It answers shoppers from your product pages, your published knowledge and your reviews, recommends the right product and checks order status.

  • Vouch

    Reviews in your shoppers' language

  • Cartify

    Upsell ideas, researched

  • ExtraSale

    Offer graphics with prompts

    Fifteen ready-made offer graphics, each with a prompt you can use in ChatGPT with your own product photo.

Software merchants can trust with their store.

A store is someone's livelihood. Our apps preview every change before it goes live, plug into Shopify the way Shopify intends, and never make promises a store can't keep.

  • Preview first

    Every change shows in a live preview with your own products. Nothing reaches your store until you save or publish.

  • Works with your theme

    Our apps install through Shopify app embeds and blocks, with no code edits. Cartify replaces the cart drawer on any theme.

  • No made-up promises

    Vouch's agent never invents discounts, urgency or delivery promises. ExtraSale says plainly that the shopper pays in a new checkout.

  • English and Hebrew

    Every app's admin works in English and Hebrew, with right-to-left support, and every storefront text is yours to write.

One team, four apps.

Rofsky Solutions is a software company that builds apps for Shopify merchants. We make four, each for one moment of the sale, and we design, build and support them ourselves.

We build AI into the work merchants already do: setting up offers, designing carts, answering shoppers and translating reviews. Then we write the guides and record the videos that explain every screen.

Our YouTube channel has full app guides and short explainers, all made by our own team.
