What are the best Klevu alternatives for ecommerce site search?

Four credible Klevu alternatives, each leading in a different lane:

• Nobi - semantic site search plus a shopping assistant in one platform, $25/month base with $0.01 per extra search. Pick when long, conversational queries are missing in Klevu - Nobi's semantic matching produces highly relevant search results, allowing merchants to get away from hand-pinning products to queries or creating special rules for every unusual query pattern (unless they want to).
• Algolia - developer-first search API with sub-50ms responses and NeuralSearch, $0.50 per 1K searches on the Grow plan. Pick when you have a search engineering team that wants full API control over ranking and the frontend.
• Searchspring - merchandiser-first search with rule-by-rule control. Mid-market plans run roughly $1,500-$3,500/month (customer-reported; Searchspring doesn't publish list prices). Pick when your team wants exact rules over what each query returns - though note Searchspring is now under the same Athos Commerce parent as Klevu.
• Findify - mature Shopify Plus app with personalization bundled in, starting at $499/month on the Essential tier. Pick when you want a packaged Shopify install with personalization included rather than upsold.

Pick by which of those Klevu pain points hurts most for your team.

Full disclosure: Nobi is our product, and it's included in this list alongside the three competitors head-of-ecommerce buyers most often weigh against it. We've aimed to be honest about Nobi's own limits and explicit about when another tool on this list is the better pick.

Why are ecommerce teams looking for Klevu alternatives?

Klevu is a capable AI search tool for Shopify, but four reasons keep coming up when ecommerce teams shop around:

• Cost relative to brand size. Smart Search starts at $249/month on the Shopify App Store and climbs once add-on modules are layered in.
• A merchandising UI that feels dated. Usable, but not the reason anyone picks the tool, and the rule list grows with the catalog.
• Personalization is available in the Expert tier only. Essential and Advanced plans do not include personalization features; you need to be on Expert to get them.
• The Athos Commerce consolidation. Klevu now sits under the same parent as Searchspring and Intelligent Reach.

None of those are dealbreakers on their own - together they push a lot of heads of ecommerce to look at what else is out there.

Klevu's published pricing on the Shopify App Store starts at $249/month for Smart Search. Personalization features are included in the Expert tier only - Essential and Advanced plans do not include them. Smart Category Merchandising pricing is not published publicly; confirm both during procurement.

Klevu, Searchspring, and Intelligent Reach now sit under the same Athos parent, so a shortlist that includes Klevu and Searchspring is really a shortlist of two products from one company. Nobi shows up on these lists when the trigger is long conversational queries the catalog can't match, or pressure to consolidate search and shopper Q&A onto one bill.

How did we pick these Klevu alternatives?

We narrowed an initial list of fifteen ecommerce search tools down to four that a head of ecommerce replacing Klevu is most likely to actually evaluate. The cut criteria: published or referenceable pricing (no pure "contact sales" entries), a real install path on Shopify or Shopify Plus, and a credible answer to one of the four reasons teams leave Klevu - cost, merchandising effort, feature bundling, or the Athos consolidation. Sources were vendor documentation, current Shopify App Store listings, and customer-reported pricing references for vendors that don't publish list prices.

Nobi is on the list because it answers two of the four Klevu pain points at once: semantic relevance for the long, conversational queries Klevu's keyword-led matching misses, and search plus shopper Q&A on a single $25/month bill instead of needing to upgrade to a higher Klevu tier to get personalization. Algolia made the cut because it has the clearest published pricing of any developer-grade option (Grow at $0.50 per 1,000 search requests above 10K, Grow Plus at $1.75 per 1,000) and a credible answer to teams who left Klevu over flexibility. Searchspring is on the list despite the Athos consolidation because it remains the most-cited Klevu alternative inside the merchandising-heavy mid-market and ships with active campaign tools Klevu's dashboard doesn't match. Findify earned a spot on referenceable pricing - $499/month Essential, $799 Professional, $1,399 Enterprise - and an AI-personalization story that maps directly to what Klevu reserves for its Expert tier.

1. Nobi

Nobi is an AI shopping platform built for heads of ecommerce whose long, conversational queries fall through Klevu's keyword-led matching. The semantic layer produces highly relevant search results for every query. That same layer powers the search bar, the results page, and the chat widget that answers product, sizing, and policy questions - search and shopper Q&A on one bill instead of having to upgrade to Klevu's Expert tier to access personalization features.

Installation is easy, just drop in a couple of lines of JavaScript and update your site with whichever custom widgets you want (most folks go with the search bar, but others are available). Brands typically go live in hours, not the multi-week cutover larger platforms require.

UNTUCKit measured a 17.1% conversion rate lift against their prior search tool over a two-month A/B test before moving Nobi to 100% of traffic.

Best for: Ecommerce teams whose long, conversational queries are missing in Klevu and who want search plus shopper Q&A handled by one platform without weekly merchandising work.

Pricing: $25/month base (includes 2,500 searches and 250 conversational messages). $0.01 per additional search, $0.10 per additional message.

Pros:

• Highly relevant search results on long, conversational queries that keyword-led matching misses; relevance comes from the latest semantic search algorithms, not manual rule tuning
• Search and shopping assistant on one platform and one bill, without needing to upgrade to Klevu's Expert tier to access personalization features
• Transparent per-unit pricing with no revenue-share or surprise tier upgrades; UNTUCKit also measured 21.3% higher revenue per searcher in the same two-month test
• Goes live in hours, not the multi-week cutover Klevu's larger deployments can take

Cons:

• Only deals with search, not category or collection pages; brands that need merchandising across the entire site beyond search will still want a dedicated merchandising tool
• Smaller third-party integration marketplace than enterprise incumbents like Algolia

Verdict: Pick Nobi if your search is missing on long, conversational queries and you want one tool covering search and shopper Q&A; skip it if your bottleneck is merchandising across category and collection pages rather than the search results page.

2. Algolia

Algolia is a developer-first search API: sub-50ms response times, a deep ecosystem of libraries and frontend widgets, and a NeuralSearch layer that adds semantic matching on top of keyword search. The strength has always been the API itself - engineering teams get granular control over indexing, ranking, and how the results render in the storefront. For a head of ecommerce replacing Klevu, Algolia is the option to look at when the reason you're leaving isn't cost or merchandising effort but the ceiling on what your team can customize.

Best for: Teams with dedicated frontend and backend developers who want full API control over the search experience and the engineering hours to build it.

Pricing: Usage-based. Grow is $0.50 per 1,000 search requests above 10K and $0.40 per 1,000 records above 100K; Grow Plus is $1.75 per 1,000 search requests above 10K with NeuralSearch gated to higher tiers; Improve is volume-based with discounts negotiated against committed usage. Mid-sized deployments typically land in the $500-$5,000/month range before any custom relevance engineering work.

Pros:

• Sub-50ms response times and fast indexing at catalog scale
• Large ecosystem of libraries, InstantSearch widgets, and platform integrations
• NeuralSearch adds semantic matching on top of keyword results
• Granular API-level control over ranking, indexing, and frontend rendering

Cons:

• Requires developers to implement and maintain; quality scales with engineering hours, not dashboard time
• Usage-based pricing can produce surprise bills during traffic spikes
• Not built for non-technical merchandising teams who want to work in a UI

Verdict: Pick Algolia if you have a dedicated search engineering team and want full API control over ranking and the storefront UX; skip it if you don't have engineers to spare or you want most of the work to happen in a merchandising dashboard rather than in code.

3. Searchspring

Searchspring is mid-market ecommerce search and merchandising built around rule-by-rule control. Merchandisers configure no-results rules, redirects, and product pinning per query pattern from a single dashboard, and the whole pitch is that the merch team - not an AI model - decides what each query returns. For a head of ecommerce leaving Klevu, Searchspring is the option to look at when the reason you're moving isn't AI capability but a merchandising UI you've outgrown. The wrinkle worth naming up front: Searchspring is now a division of Athos Commerce alongside Klevu and Intelligent Reach, so a shortlist that swaps one for the other is really shopping inside the same parent company.

Best for: Merch teams that want exact, rule-by-rule control over what each query returns and have the bandwidth to maintain that rule list as the catalog grows.

Pricing: Not published on the Searchspring site. Third-party references put mid-market plans in the $1,500-$3,500/month range; confirm directly with Searchspring before budgeting.

Pros:

• Rule-level control means merchandisers know exactly what each query pattern returns and can audit any result back to a specific rule
• Redirect-on-zero-results option sends dead-end queries to a curated landing page instead of a generic fallback list
• Lives inside the same merchandising dashboard the team already uses for campaigns and category rules, so adoption is fast for merch-led teams

Cons:

• Rule list grows one-to-one with query patterns; every unusual query that misses needs its own new rule, and the maintenance load compounds with catalog size
• Less AI-native than newer engines, so long, conversational queries are still a weak spot
• Now a division of Athos Commerce alongside Klevu and Intelligent Reach

Verdict: Pick Searchspring if you want exact rule-by-rule control and have the team to maintain it; skip it if conversational queries are your main miss reason, or if the Athos overlap with Klevu defeats the point of switching.

4. Findify

Findify is a Shopify-focused search, merchandising, and product-feed engine that bundles Smart Collections, ranked product feeds, and personalization into the base product. For a head of ecommerce on Klevu who needs to upgrade to the Expert tier to get personalization, Findify is worth comparing: a mature packaged Shopify app where AI ranking, Smart Collections, and personalization are part of what you're already paying for at every plan level.

Best for: Shopify Plus brands that want a mature packaged app with personalization included across plans rather than gated to a higher tier.

Pricing: Essential at $499/month, Professional at $799/month, Enterprise at $1,399/month.

Pros:

• Mature Shopify app with plug-and-play AI ranking on install
• Smart Collections and ranked product feeds give non-technical merchandisers a usable workflow out of the box
• Personalization features sit inside the base product instead of being upsold as a separate license

Cons:

• Merchandising workflows still require manual tuning; relevance leans on what the merchandiser configures
• Pricing climbs past $1,000/month quickly once you move to Professional or Enterprise tiers

Verdict: Pick Findify if you want a mature packaged Shopify app with personalization bundled into the base price; skip it if your team doesn't have the bandwidth to keep tuning merchandising rules, or if Professional-tier pricing eats the savings versus Klevu.

How should a head of ecommerce pick between these Klevu alternatives?

Sort by the job your team needs done, not by demo polish. The four tools on this list each win a different lane, and the right pick falls out fast once you name the bottleneck out loud instead of reading another comparison grid.

If long conversational queries are missing in Klevu and your merch team is buried in rules, Nobi is the closest match. The semantic relevance layer learns from your catalog and shopper signals, so merchandisers stop hand-pinning products to queries every week, and the same engine powers the chat widget that handles shipping, sizing, and policy questions. Pricing is $25/month base (2,500 searches and 250 messages included), then $0.01 per additional search and $0.10 per additional message - one usage-based bill without needing to step up to a higher Klevu tier to get personalization features. Skip Nobi if your real bottleneck is merchandising across category and collection pages rather than the search results page itself.

If your engineers want to own search end-to-end, Algolia is the most direct fit. The API gives a search engineering team granular control over indexing, ranking, and how results render, and the Grow tier ($0.50 per 1,000 search requests above 10K) is the clearest published pricing of any developer-grade option. The cost is engineering hours; the payoff is a search experience built exactly the way you want it.

If your merch team wants exact rule-by-rule control, Searchspring works - with the caveat that it now sits under Athos Commerce alongside Klevu, so swapping one for the other isn't really leaving the parent company. If you want a packaged Shopify app with personalization included in the base product, Findify covers that lane from $499/month.

One last thing: run a controlled A/B test on your own traffic before committing past a quarter. None of these vendors' AI claims should be taken on faith - UNTUCKit ran Nobi side-by-side against their prior tool for two months before deciding.

Frequently asked questions

Common questions about replacing Klevu - how long the cutover takes, what happens to existing merchandising rules, and how the Athos Commerce consolidation affects your shortlist.

How long does it take to migrate from Klevu to one of these alternatives? It depends on the tool. Nobi goes live in hours. Findify is a packaged Shopify app and lands in a similar window. Algolia is a multi-week build because you're wiring an API into the storefront and writing the frontend code yourself. Searchspring sits between the two: faster than Algolia, slower than the packaged options, with merchandiser onboarding adding time on top.

What happens to my Klevu merchandising rules when I switch? They don't carry over. Searchspring, Findify, Algolia, and Nobi each have their own merchandising model, and any pinned products, redirects, or no-results rules need to be rebuilt in the new tool. Nobi rebuilds the least because semantic relevance learns from your catalog and shopper behavior instead of a rule list; Searchspring rebuilds the most because the rule list is the product.

Does the Athos Commerce parent affect my Klevu contract or roadmap? Klevu and Searchspring now sit under the same parent, so a swap between the two stays inside one company. It's a reason to look at Nobi, Algolia, or Findify if leaving the Athos umbrella is part of why you're moving.

Should I run the new tool in parallel and A/B test before cutting over? Yes. Split traffic, watch search CVR for a few weeks, and only cut over once the numbers hold up on your own catalog.
