1. Boost AI Search and Discovery

Best for: Growing Shopify stores that want search, filtering, merchandising, and recommendations in one Shopify native app.

Boost prices on GMV rather than product count: its own pricing explainer says GMV is your total sales revenue before discounts, returns, or taxes, and your Base GMV is the average of the last three months, used to assign your plan (Source: Boost pricing). The App Store listing prices Launch from $29 a month, up to $159 a month for stores under $50,000 monthly GMV, and Convert from $299 a month, up to $599 a month for stores under $400,000 monthly GMV, with a 21-day free trial (Source: Boost AI Search and Discovery on the Shopify App Store). Boost's changelog shows active development of discovery features such as Predictive Bundles appearing inside the instant search dropdown (Source: Boost changelog).

Pros

• GMV based pricing means a huge catalog does not punish you the way per product or per record pricing can (Source: Boost pricing)
• Search, filters, merchandising, and recommendations live in one app and one Shopify bill (Source: Boost AI Search and Discovery on the Shopify App Store)
• A 21-day trial plus a 30-day money back guarantee gives you a full selling cycle to judge search revenue (Source: Boost pricing)

Cons

• Overage is charged at $2 per additional $1,000 of exceeded GMV, so a breakout month raises the app bill automatically (Source: Boost pricing)
• You cannot downgrade to a plan with a GMV limit lower than your current Base GMV, so one strong quarter locks in a higher tier for a while (Source: Boost pricing)
• There is no annual subscription or one time payment option; it is monthly only, billed through Shopify (Source: Boost pricing)

Pricing: Launch from $29/month, up to $159/month for stores under $50K monthly GMV; Convert from $299/month. Full tiers at https://boostcommerce.net/platform/pricing, checked 6 November 2026.

Skip it if: Your GMV is high but your search usage is low, since you pay on sales whether or not shoppers use search.

Unique detail: Legacy add ons such as AI Powered Search and AI Powered Recommendation were billed separately at $89 each, and the vendor's legacy pricing overview states subscription and usage fees for add ons are non refundable, so check which generation of the product you are buying (Source: Boost support).

Fits: Growing stores from launch stage up to about $400,000 a month in GMV, especially catalogs where filters drive the sale.

Pick this if you want one native app, pricing that follows your sales rather than your SKU count, and a trial long enough to measure search conversion properly.

2. Doofinder

Best for: Stores that want flat, published pricing for search, recommendations, and quizzes.

Doofinder's own pricing page lists Basic at $61 a month on monthly billing, or $55 a month billed yearly, with up to 10,000 requests a month for each product, Pro at $186 a month for up to 150,000 requests per product, and Advanced at $436 a month for up to 400,000 requests per product, with Enterprise custom priced (Source: Doofinder pricing). Every plan includes a set number of requests for each product, meaning Search, Recommendations, and Quiz each draw on their own allowance (Source: Doofinder pricing). The same tiers appear on its Shopify App Store listing (Source: Doofinder on the Shopify App Store).

Pros

• Flat published tiers make budgeting simple, with no percentage of sales and no per record fees (Source: Doofinder pricing)
• Search, recommendations, and a product quiz sit under one subscription (Source: Doofinder pricing)
• Annual billing takes 10 percent off the monthly rate (Source: Doofinder pricing)

Cons

• The annual discount comes with a catch stated on the pricing page: annual payment is a one time, non refundable payment, so a bad fit costs you the year (Source: Doofinder pricing)
• Request allowances are per product, so heavy quiz or recommendation traffic does not borrow from unused search requests (Source: Doofinder pricing)
• The jump from Basic at 10,000 requests to Pro is a threefold price rise, which stings stores in the middle

Pricing: Basic $61/month monthly billing or $55/month billed yearly; Pro $186/month; Advanced $436/month. Full tiers at https://www.doofinder.com/en/price-platforms, checked 6 November 2026.

Skip it if: You need deep Shopify native merchandising rules per collection inside the same tool, where Boost or Searchspring go further.

Unique detail: Doofinder counts requests separately for each product in the bundle, so your search allowance and your quiz allowance are different buckets (Source: Doofinder pricing).

Fits: Small to mid size stores doing up to 150,000 search and recommendation requests a month that value a predictable invoice.

Pick this if you want to know your search bill to the dollar every month and you like the idea of a product finder quiz feeding the same engine.

3. Algolia AI Search and Discovery

Best for: Growing stores with developer support that need the fastest, most controllable search engine.

Algolia's free Build plan includes 10,000 search requests a month, and its Grow plan includes 10,000 search requests a month and then charges $0.50 per additional 1,000 search requests, with 100,000 records included and then $0.40 per additional 1,000 records (Source: Algolia pricing). Its support documentation is unusually precise about metering: requests and records are billed independently, unused allowance does not roll over, a record is counted across all indices including replicas, and every call to the search endpoint counts as one search request whether or not it returns results and whether or not the query is empty (Source: Algolia support). The Shopify listing notes that external charges by Algolia may apply separately from your Shopify invoice, and that the listed tiers carry self service support only (Source: Algolia on the Shopify App Store).

Pros

• The free Build plan is a real starting point with 10,000 search requests a month included (Source: Algolia pricing)
• Pay as you go Grow pricing scales smoothly with actual search demand instead of tier jumps (Source: Algolia pricing)
• Deep control over ranking, facets, and synonyms for stores whose catalog language is complex

Cons

• Every search endpoint call counts, even an empty query or a no results query, so a chatty front end implementation inflates the bill (Source: Algolia support)
• Unused monthly allowance does not roll over, and records in replica indices count toward your record total (Source: Algolia support)
• Charges are billed by Algolia separately from Shopify, and guaranteed support responses and setup help sit behind a sales conversation (Source: Algolia on the Shopify App Store)

Pricing: Build free; Grow pay as you go, $0.50 per additional 1K search requests after 10K included and $0.40 per additional 1K records after 100K included; Grow Plus at $1.75 per additional 1K search requests. Full tiers at https://www.algolia.com/pricing/grow-plan, checked 6 November 2026.

Skip it if: You have no developer help and want a set and forget app, since Algolia rewards technical tuning and punishes sloppy implementation in the invoice.

Unique detail: For records billing, Algolia discards your three highest record days each month, a peak shaving rule spelled out in its support docs (Source: Algolia support).

Fits: Stores with high search volume, large or multi index catalogs, and someone technical to keep request counts lean.

Pick this if search is a core revenue channel, you can measure cost per search against conversion, and you want an engine that will not cap your growth.

4. Fast Simon

Best for: Fashion and lifestyle stores that think in shopping sessions and love visual merchandising.

Fast Simon's App Store listing offers a free plan with 100 monthly sessions, including AI based instant search and autocomplete, typo correction, and daily sync, then Starter at $39.99 a month for 2,000 monthly sessions, Essential at $99.99 a month for 10,000 monthly sessions, and Top Pro at $299.99 a month for 30,000 monthly sessions (Source: Fast Simon on the Shopify App Store). Higher tiers shorten sync to hourly and add features such as Did You Mean, synonyms, custom product filters, and SKU search (Source: Fast Simon on the Shopify App Store). Its own pricing page now focuses on Enterprise, where onboarding, a dedicated Customer Success Manager, and SLA backed uptime are included, and implementation pricing depends on how much of the work its team does (Source: Fast Simon pricing).

Pros

• A free plan with real AI search lets you test session based pricing before committing (Source: Fast Simon on the Shopify App Store)
• Session pricing bundles search, filters, and merchandising pageviews into one easy unit to forecast (Source: Fast Simon on the Shopify App Store)
• Annual billing on the listing saves about 17 percent against monthly (Source: Fast Simon on the Shopify App Store)

Cons

• The free plan syncs only daily, so a fast moving catalog can show sold out or mispriced items in search for up to a day (Source: Fast Simon on the Shopify App Store)
• Session caps mean a traffic spike from a sale event can push you into a higher tier mid growth spurt (Source: Fast Simon on the Shopify App Store)
• Beyond the listed tiers, pricing turns into a proposal: its helpdesk notes plans vary by product count, search volume, and modules, and asks you to request a price proposal (Source: Fast Simon pricing)

Pricing: Free plan with 100 monthly sessions; Starter $39.99/month; Essential $99.99/month; Top Pro $299.99/month. Full tiers at https://apps.shopify.com/instant-search, checked 6 November 2026.

Skip it if: Your catalog changes hourly and you cannot accept daily sync on a cheap tier, or your session volume makes per session pricing unpredictable.

Unique detail: Fast Simon counts a session rather than a query, so a shopper who searches five times in one visit still counts once, which can make it cheaper than per request rivals for search heavy audiences (Source: Fast Simon on the Shopify App Store).

Fits: Stores doing up to about 30,000 shopping sessions a month on listed plans, especially apparel and accessories where look based browsing matters.

Pick this if your shoppers browse visually, your sessions are worth more than your raw query count, and you want AI search live without a big integration project.

5. Searchspring (Athos Commerce)

Best for: Larger growing catalogs that want a managed, merchandising led search partner.

Searchspring now sits under the Athos Commerce brand, and its site presents one platform covering AI search, AI product recommendations, AI product bundling, and AI merchandising, with pricing available only through a personalized demo built around your catalog (Source: Athos Commerce). Its Shopify listing is free to install with tiered offerings billed outside a simple published rate card (Source: Searchspring on the Shopify App Store). The vendor's own guidance describes a human data audit and consultation with every prospect before a contract is signed, plus white glove integration support (Source: Athos Commerce).

Pros

• A human data audit before signing means your messy catalog data gets cleaned as part of onboarding (Source: Athos Commerce)
• Search, recommendations, bundling, and merchandising strategy come from one specialist vendor (Source: Athos Commerce)
• White glove integration suits teams without spare developer time (Source: Athos Commerce)

Cons

• No published price anywhere on its site or listing, so you cannot budget or compare without entering a sales process (Source: Athos Commerce)
• Demo led onboarding is slower than a self serve install when you need better search this week (Source: Athos Commerce)
• A managed platform is harder to leave: merchandising campaigns and rules built in its console do not transfer automatically to a rival tool

Pricing: Quote only. Pricing: Check current price via a demo at https://searchspring.com/, checked 6 November 2026.

Skip it if: You are a small team that wants transparent pricing and a same day install.

Unique detail: The vendor builds a data audit by human specialists into the pre contract process, which is rare in a category that usually hands you a dashboard and wishes you luck (Source: Athos Commerce).

Fits: Stores with large, messy catalogs and enough revenue that merchandising labor, not app fees, is the real cost.

Pick this if your catalog data is the bottleneck, you want experts to fix it with you, and you are comfortable pricing by conversation.
