Boost AI Search & Filter alternative: keep it, or add search by description

• You need filters and facets on collection pages. OneSite Assistant has none and does not try to replace them.
• You want a search bar with suggestions and results pages, and merchandising rules for a large catalogue.
• You want a long-established app: its Shopify listing dates from 2017.

• Your shoppers describe instead of naming: “something for my dad who likes history”, “a quiet game for four”.
• Your catalogue is niche, where the useful attributes (edition, metal, notes, player count) live in descriptions and not in a filter.
• You want to see what your search could not answer: when nothing fits, the assistant says so and, where your consent settings allow, takes a contact and writes the request to your Requests tab.
• You do not want to touch theme code: it is a theme app extension, one block you switch on and off.

Reviews on its Shopify listing are mostly positive, and the most common praise is a support team that answers quickly and stays with a problem. We read them in October 2026. The complaints are a minority, and they come back to the same few themes:

• Price steps that follow store size or product limits.
• Harder setup and styling on customised themes; some reviewers needed a developer.
• A few reviews say support went quiet after the sale; some say it answered only after a one-star review.
• A few reviews report code left in the theme after uninstalling. The developer’s replies attribute those cases to the store’s theme.

OneSite Assistant is a separate block in your theme. It does not replace your search bar or your filters, so a store can keep Boost for browsing and add the assistant for the shoppers who do not know what to type.

Do not decide from a feature table, ours included. Open your store’s search log and take five real queries: two that found the right product, two that found nothing, one written as a sentence. Run them through the tool you use today and through the OneSite Assistant demo, and compare what comes back.

If the tool you already use answers them well, keep it. If the sentence-style queries come back empty, that is the gap we are built for.

Install OneSite Assistant from the Shopify App Store. In the Shopify app you approve the plan right after install and start with a free trial. See the pricing and the questions worth asking before you install.
