Superior solution

Why Boost AI is better than Rebuy

Boost is a full-funnel product discovery and merchandising platform. It helps shoppers find the right product faster, helps teams control what shows up and why, and increases revenue from search to cart.

Personalization you can explain and steer

Blend behavioral signals with clear rules and overrides so recommendations stay aligned with margin, availability, and merchandising strategy instead of feeling like a black box.

Central merchandising control across the storefront

A single merchandising layer lets teams pin, boost, demote, and curate results across search and collections to drive the outcomes you actually care about.

Cart upsells without cart takeover risk

Get AOV lift without replacing the cart. Cart Drawer Upsell matches the theme cart drawer and avoids dual-cart headaches, making it easier to launch and maintain over time.

Filters built for real catalog complexity

Deep faceted filtering (variants, metafields, multi-select) keeps big catalogs shoppable and reduces “browse fatigue” on collection pages.

Delivers robust and feature-rich instant search capabilities, elevating our website's product search functionality. Our customers are delighted with the seamless product discovery and appreciate the added value of relevant product recommendations.

Whiskers N Paws

We had started with other more expensive and "premium" apps for search, and for merchandising/ collections. Big name apps that you may be considering, you can guess who they are. Boost outperforms anything else we tried. Whatever the issue, we've been able to get good responses and results.

APL

I always recommend Boost as the ideal app for Search/Filtering, but even more importantly product recommendation widgets. Coming from a very pricey competitor, Boost blows them out the water with value and most important and above all, customer service and technical support.
