# Rofsky Solutions > Rofsky Solutions builds AI-native apps for Shopify merchants: BundleUp for bundles and quantity breaks, Cartify for the cart drawer, Vouch for product reviews and an AI sales agent, and ExtraSale for offers and surveys on the thank-you page. Rofsky Solutions is a software company that builds apps for Shopify merchants. Each of its four apps covers one moment of a sale: the product page (BundleUp), the questions before buying (Vouch), the cart (Cartify) and the thank-you page (ExtraSale). All four are listed on the Shopify App Store with a 5.0 rating (149 reviews in total as of October 2026). The admin of every app is available in English and Hebrew. Contact: hello@rofskysolutions.com. ## Apps - [BundleUp](https://rofskysolutions.com/bundleup): Bundles, quantity breaks and free gifts on the product page, built by AI from a sentence or a screenshot. BundleUp creates one automatic Shopify discount that matches the quantities in the cart, so shoppers never type a code. - [Vouch](https://rofskysolutions.com/vouch): Product reviews with photos, AI translation and video reels, plus an AI sales agent that talks with shoppers. - [Cartify](https://rofskysolutions.com/cartify): A cart drawer with upsells, a reward bar and free gifts, designed by chat with the AI Cart designer. Each tier of the reward bar can be a milestone message, a real order discount, or a free product that is added automatically when the cart reaches it. - [ExtraSale](https://rofskysolutions.com/extrasale): Upsell offers and surveys on the thank-you page. The buy button opens a pre-filled checkout for a new order. It is not a one-click upsell. The buy button opens a new checkout with the product, discount and the shopper's details pre-filled. The shopper pays there, and it becomes a separate order. ## Shopify App Store listings - [BundleUp on the Shopify App Store](https://apps.shopify.com/bundle-up-1): rated 5.0 from 72 reviews (October 2026).
