Rebuy Personalization Engine is an AI-powered suite for personalizing the entire Shopify shopping journey — from product discovery and search through the cart, checkout, and post-purchase. It is organized into four core packages — Cart & Merchandising, Checkout & Post-Purchase, Search & Collections, and Flows & A/B Testing — so you can run upsells, cross-sells, and smart merchandising from one platform, with the goal of lifting both average order value (AOV) and lifetime value (LTV).
Key features
- Smart Cart: an AI-powered, fully customizable slide-out cart with product recommendations, in-cart rewards, and free-shipping progress bars.
- AI recommendations everywhere: personalized upsells and cross-sells on product pages, in search and collections, at checkout, and post-purchase.
- Checkout & post-purchase: data-fueled recommendations at checkout plus one-click post-purchase offers and Re-Order Landing Pages.
- Smart Flows & A/B testing: build automated personalization rules and split-test them to see what converts.
- Deep integrations: works with Klaviyo, Recharge, Attentive, Okendo, Malomo, Route, and Shopify Flow.
Pricing and rating
Rebuy has moved to a flexible, usage-based pricing model. There is a free plan for development stores and a 14-day free trial, after which paid plans start as low as $25/month and scale with your store's monthly order volume — you customize your plan and pay only for the packages you use, saving up to 30% when you bundle them. Rebuy also offers Rebuy Monetize, a free add-on that earns you around $0.20–0.35+ per order by monetizing your thank-you page.
The app holds a 4.7 rating from 818 reviews, with 95% at five stars. Merchants repeatedly highlight the lift in sales, AOV, and conversion, the ability to consolidate several apps into one (which can improve site speed and cut costs), and — above all — the responsiveness and strategic guidance of Rebuy's customer success team.
Pitfalls
Rebuy is deep, and that depth can mean a learning curve when configuring its more advanced flows and merchandising rules, though no-code and low-code options reduce the need for developers. And because pricing is usage-based, costs grow with your order volume, so higher-volume stores should model the spend before committing.
Conclusion
Rebuy is one of the most complete personalization platforms on Shopify, pairing a powerful Smart Cart and AI recommendations across the journey with strong A/B testing and a support team merchants consistently praise. With a more flexible, usage-based price that now starts at $25/month and a free Monetize add-on, it is more accessible than it used to be — and a strong fit for growing stores that want to personalize and test at every step.
