Sledge vs Boost AI Search: which should you choose?
You pay a premium every month for sharp search, and the dashboard hands you charts: top queries, zero-result terms, conversion by facet. None of it tells you which one to fix first, or what fixing it is worth. The report gets a glance, the bill keeps climbing with usage. Here's the page for a tool that names the next move instead of handing you homework.
Boost AI Search & Filter is a leading Shopify search app: around 1,579 reviews at 4.7 stars, polished, used by large brands. Sledge covers search too, then adds the selling layer: nine offer types, upsell, promotions, reviews, wishlist, and Growth Intelligence telling you what to fix. Boost's price scales by plan and usage. Sledge stays flat.

Should you pick Boost or Sledge?
Choose Boost AI Search if:
- Enterprise-scale search and discovery is the whole job, and the budget allows a dedicated tool for it.
- You want the specialist: polished, around 1,579 reviews at 4.7 stars, large brands on the customer list.
- Predictive bundles inside recommendations are as far into offers as you need to go.
Choose Sledge if:
- You want search plus the tools that sell after it: nine offer types, upsell, promotions, a cart drawer.
- You want Growth Intelligence telling you what to fix, what it's worth, and what it earned.
- You want reviews and wishlist in the same app instead of two more subscriptions.
- You want one flat price that doesn't move with usage.
// Deep dive 1 · Scope
What happens after the shopper finds the product?
Boost is genuinely strong at the finding part. Search, filters, and recommendations are the whole product, and the polish shows; large brands run Boost for a reason.
Sledge treats "found" as the halfway point. The shopper who searched is mid-decision, so Sledge puts an offer inside the moment: a bundle card in the search results, a free gift landing in the cart, a build-your-own bundle page. Nine offer types, plus upsell, promotions, and the cart drawer, all from the same app that ran the search.
Boost does include predictive bundles inside its recommendations, a genuine plus. The difference is breadth: bundles living inside recommendations versus an offer toolkit across the storefront, from the search bar to the cart.
If your search app's job ends at "help shoppers find products," Boost fills it. Sledge applies for the second job too: sell while they look.
// Deep dive 2 · Descriptive vs prescriptive
What does Growth Intelligence add that dashboards don't?
Boost's analytics are descriptive, and good at it: dashboards and conversion charts showing how search and discovery performed. If your team turns charts into to-dos, that's real value.
Growth Intelligence skips the homework and hands in the answer. It reads your orders, searches, and shopper behavior, names the fix, and attaches a dollar estimate. Click it and the offer opens pre-filled. Review it, save it, and it measures the result against your real sales, so the next suggestion is sharper than the last.
Insights that tell you what to do. Not just what happened.
// Deep dive 3 · Pricing
How do Boost and Sledge pricing compare?
Boost's plans scale as your store grows. That model is common for dedicated search tools, and it's honest: a bigger store costs more. Just budget for the bill to grow as you do.
Sledge runs flat plans: $29.99, $89.99, $199, or $399 a month, chosen by catalog size and how often you want Growth Intelligence reporting. Usage doesn't move the bill. At very high Sledge-attributed revenue, new AI generation pauses until the month resets, and every storefront tool keeps running. Your price doesn't climb when your sales do.
// Migration note
Switching from Boost to Sledge: what's involved?
Carefully, and that's a compliment to search. The search bar is your store's front door, so don't swap it on a whim.
- Start the free trial and set up Sledge search and filters.
- Judge result quality on your own catalog, with the queries your shoppers type.
- Then turn on what Boost doesn't carry: bundles in the results, reviews, wishlist, Growth Intelligence.
If Boost's search wins and search is the whole job, stay with Boost. That's the right call, and this page says so in writing. If Sledge's search holds up and the selling layer earns its keep, consolidate to one app and one bill. Sledge uninstalls clean either way.
