Rebuy Review – AI-Powered Shopify Personalization, Smart Cart & Post-Purchase Upsells

Rebuy Overview

Rebuy is an AI-powered ecommerce personalization platform built specifically for Shopify and Shopify Plus brands. It personalizes every step of the shopping journey — product page recommendations, the Smart Cart drawer, checkout, post-purchase upsells, search, and email/SMS flows — with the explicit goal of lifting AOV, ROAS, and LTV. Used by 50,000+ Shopify stores, Rebuy has attributed more than $3.8B in new revenue to merchants using the platform.

The core packages are Cart & Merchandising (including the flagship Smart Cart drawer), Checkout & Post-Purchase upsells, Search & Collections, and Flows & A/B Testing. Pricing is hybrid: a base monthly fee (from $99/month on Starter to $499/month on Pro) plus a small percentage of Rebuy-attributed revenue (0.9% down to 0.5%), with a single-bundle Platform One plan at roughly $534/month and a custom Enterprise tier. There are 790+ Shopify App Store reviews with strongly positive sentiment; we do not quote an aggregate score or star distribution we have not verified.

Real-time AI surfaces hyper-relevant upsells and cross-sells based on shopper behavior, purchase history, geo-location, traffic source, and custom data signals.

Post-Purchase Upsells & Downsells
