Shopify’s native search handles basic keyword matching, but it breaks down when shoppers misspell words, use natural phrases, or search by SKU. AI-powered search apps fill that gap by understanding intent, correcting errors, and surfacing the right products even when the query is imprecise. If your store has more than a few hundred products, the difference shows up directly in conversion rates.
For AI search, filters, typo tolerance and pricing across major tools, see our Shopify search app comparison.
Our top pick: ExpertRec
ExpertRec delivers AI-powered semantic search, full typo tolerance, unlimited custom filters, and detailed analytics starting at $9/month. It installs in minutes without theme edits and works on catalogs of any size. For most Shopify merchants who need more than Shopify’s built-in search but do not want enterprise pricing, it is the strongest all-round option.

ExpertRec
ExpertRec is built specifically for ecommerce catalogs and handles semantic search, typo correction, synonym matching, and SKU-level search out of the box. The typo tolerance works at the character level, so queries like “bleutooth headphons” still return the right products. Filters are fully customizable: price, size, brand, color, availability, tags, and custom metafields all work without developer involvement. The analytics dashboard shows zero-result queries, top search terms, and click-through rates, which is directly useful for improving your catalog. Plans start at $9/month for small stores, making it the most accessible full-featured option in this comparison. If you also want to fix Shopify’s missing SKU search in suggestions, ExpertRec handles that by default.
Best for: Small to mid-size Shopify stores that need advanced AI features at a predictable monthly cost.
Algolia
Algolia is one of the most widely used search platforms across the web, and its Shopify integration brings that same infrastructure to ecommerce stores. Its NeuralSearch product combines vector and keyword search to handle intent-based queries well. Algolia’s autocomplete and typo tolerance are both strong, and the documentation is thorough enough that developers can customize behavior at a granular level. The challenge for Shopify merchants is pricing: Algolia charges per search operation, and costs can rise quickly for stores with high traffic or complex queries. The free tier covers basic usage, but most merchants will need a paid plan once they grow. For a detailed breakdown of how the integration works, see our guide on the Algolia Shopify integration.
Best for: Developer-heavy teams or enterprises that want maximum control and already have Algolia expertise in-house.
Searchspring / Athos
Searchspring, now operating under the Athos Commerce brand, targets mid-market and enterprise retailers with a full product discovery suite that includes search, merchandising, personalization, and recommendations. The platform’s AI ranking models factor in conversion data, inventory levels, and behavioral signals to sort results intelligently. Setup involves more onboarding than plug-and-play tools, and pricing is custom with no published tiers, which makes it difficult to evaluate without a sales conversation. For more detail on what to expect from Searchspring on Shopify, see our Searchspring Shopify app overview. It is not the right fit for stores under $1M GMV, but for large catalogs with complex merchandising requirements, it is worth evaluating.
Best for: Enterprise retailers with large catalogs and dedicated merchandising teams.
Boost AI Search and Filter
Boost Commerce is a popular choice on the Shopify App Store and has a solid reputation among merchants who want AI search without a steep learning curve. The app handles semantic search, typo tolerance, and collection filters well, and its visual merchandising tools let store owners pin products, boost new arrivals, and manage out-of-stock visibility. Analytics are functional but lighter than ExpertRec or Fast Simon. You get query volume and click data, but fewer drill-down options. At $19/month for the entry plan, it sits in a reasonable price range for growing stores. The main limitation is that heavy customization (custom ranking logic, advanced synonym rules, or metafield filters) requires a higher plan or support involvement.
Best for: Shopify merchants who want a reliable AI search upgrade without complex configuration.
Fast Simon
Fast Simon (formerly InstantSearch+) combines AI search with personalization, upsell widgets, and collection sorting into one platform. The search quality is strong, and the personalization layer adapts results based on individual shopper behavior over time. The analytics suite is one of the better ones in this group, covering zero-results rates, revenue attribution per search session, and A/B testing for ranking rules. Starting at $39.99/month, Fast Simon is priced higher than Boost or ExpertRec, and costs scale with store size. For stores that want search, recommendations, and collection optimization from a single vendor, it offers good bundled value.
Best for: Mid-size to larger Shopify stores that want AI search bundled with personalization and upsell features.
Klevu
Klevu is a well-established AI search platform with a strong track record in ecommerce. Its search model is trained specifically on retail data, which gives it good out-of-the-box relevance for product catalogs compared to general-purpose search engines. Klevu also includes product recommendations and category page merchandising as part of its suite. Pricing is custom and generally positions Klevu as a premium option. Most merchants report monthly costs well above the entry-level tools in this list. The platform works best when there is a technical resource available to configure the integration properly, as the default setup covers the basics but the real value comes from tuning ranking rules and feed configurations.
Best for: Established Shopify Plus stores or those migrating from another enterprise search tool.
Shopify Search and Discovery (Native)
Shopify’s own Search and Discovery app is free and available to all merchants. It supports basic synonym rules, product boosting, and filter configuration across collections. For very small stores with simple catalogs, it is a reasonable starting point that requires no additional cost or setup. The gaps become apparent quickly: typo tolerance is limited, semantic search is minimal, and there is no SKU-level matching in the search suggestion dropdown, a known issue that causes problems for stores where customers search by product code. If your store is growing and you are seeing high exit rates from the search results page, Search and Discovery is likely not keeping up with demand. It also lacks meaningful analytics beyond what Shopify’s base reports provide.
Best for: Brand-new stores with fewer than 50 products and no dedicated search budget.

Key Features to Evaluate Before You Choose
Beyond the comparison table, a few specific capabilities tend to separate good search from great search in practice.
Typo tolerance
A shopper who types “blak sneakrs” should see black sneakers, not a blank results page. Solid typo tolerance is non-negotiable for any store with more than a few dozen products. ExpertRec’s approach to typo correction in Shopify search handles character substitutions, missing letters, and common transpositions automatically.
Synonym support
Shoppers use different words for the same product: “couch” vs. “sofa”, “trainer” vs. “sneaker”. Without synonym rules, those variations produce separate result sets. Most paid apps in this comparison support synonym management, but the quality of the default synonym dictionary and the ease of adding custom synonyms varies. See how synonym search works in ExpertRec for a practical example of how this improves product discovery.
SKU and variant search
If your customers search by product code, model number, or variant ID, your search bar needs to index those fields. Shopify’s native search does not surface SKUs in the suggestion dropdown. Third-party apps handle this differently. Some index variants fully, others only at the product level. Read more about Shopify’s default SKU search gap and how to fix it.
Autocomplete quality
A well-configured autocomplete dropdown does two things: it saves the shopper time and it guides them toward products you actually stock. The best implementations show product thumbnails, prices, and category suggestions alongside text completions. Apps that only show text strings miss an opportunity to reduce search-to-product time. For more on what separates good autocomplete from basic, see our notes in the full comparison.
Frequently Asked Questions
Which Shopify search app has the best autocomplete?
ExpertRec and Algolia both deliver strong autocomplete with product thumbnails, prices, and category suggestions appearing as the shopper types. Fast Simon’s autocomplete also includes personalization signals, showing different suggestions based on browsing history. Boost AI Search and Filter covers the basics well. Shopify Search and Discovery provides only text-based suggestions with no product images, which is noticeably thinner than the third-party options.
What does AI search cost on Shopify?
Costs vary significantly. ExpertRec starts at $9/month for small stores with enterprise plans available for larger catalogs. Boost AI Search and Filter starts at $19/month. Fast Simon starts at $39.99/month and scales with order volume. Algolia uses usage-based pricing with a free tier that covers low-volume stores. Searchspring/Athos and Klevu both use custom pricing negotiated directly with sales teams, typically targeting stores at the mid-market or enterprise level. Shopify Search and Discovery is free.
Can I use AI search with Shopify’s free plan?
Shopify’s free trial allows app installs, and most AI search apps offer a free trial period of 7 to 14 days regardless of your Shopify plan. Once your trial ends, you will need both an active Shopify subscription and an active app subscription to keep the AI search running. There is no permanently free AI search option beyond Shopify’s own Search and Discovery app, which has significant feature limitations.
How do I migrate from Shopify’s default search to a third-party app?
Most AI search apps on Shopify install through the Shopify App Store and replace the default search bar automatically via theme app extensions or script injection, with no manual code changes required. You configure filters, synonyms, and ranking rules inside the app’s dashboard. The main migration tasks are setting up synonym rules for your product vocabulary, reviewing which product fields to index (including SKUs and metafields), and checking that your theme’s search input selector is recognized by the app. Most apps complete a full catalog index within minutes to a few hours depending on catalog size.
Which app handles typo tolerance best?
ExpertRec and Algolia are both consistently strong on typo tolerance, handling character substitutions, phonetic variants, and missing letters without configuration. Boost AI and Fast Simon also handle common typos well at the default settings. Klevu and Searchspring have solid typo handling but may require some tuning for domain-specific product names or unusual SKU formats. Shopify Search and Discovery has the weakest typo tolerance of any option in this comparison. A single character transposition can return zero results.
Do any Shopify search apps include product recommendations?
Yes. Fast Simon, Klevu, and ExpertRec all include product recommendation widgets as part of their platforms. These appear on product pages (“you may also like”), in the search results panel, and in some cases on the cart page. Recommendations are driven by behavioral data: what other shoppers viewed or bought after similar searches. Boost AI Search and Filter focuses primarily on search and filters, with lighter recommendation capabilities. Algolia offers recommendation features through its Recommend product, though it is a separate module from its core search offering.
Is ExpertRec compatible with Shopify Plus?
Yes. ExpertRec works on all Shopify plans including Shopify Plus. Enterprise plans include dedicated support, custom indexing configurations, and SLA options suited to high-volume stores. The app installs through the standard Shopify App Store process on Plus stores the same way it does on Basic or Shopify plans, without requiring custom Liquid code or theme modifications.
