Apex vs Shoplift vs Intelligems: 2026 Comparison for Online Shops

01How Do Apex, Shoplift and Intelligems Compare at a Glance?

Sources used: shoplift.ai, the Shoplift documentation, intelligems.io, the Intelligems documentation, and both Shopify App Store listings.

02What Is Each Tool Built For?

Shoplift describes itself as “the Shopify-native A/B testing and conversion rate optimization (CRO) platform built for high-growth DTC brands”. Tests run on the shop’s own templates, so a merchant who already maintains a Shopify theme works in a tool they know.

Intelligems leads with profit. Its homepage says: “Decide Confidently. Grow Profitably. Test pricing, offers, content, and more, powered by AI that brings your data into every decision.” Its pricing page puts it more sharply: “Most tools optimize for clicks. We optimize for profit.”

Apex by DRIP is an A/B testing platform for companies selling online that predicts which tests will win before they go live, built on one of the largest A/B test databases in e-commerce. It has three layers. The test memory holds 4.3 million A/B tests from 151,000 shops, collected since 2011, and every test idea gets a Likelihood to Win before launch. The testing tool builds, launches and evaluates tests directly in the shop, with heat maps per variant, profit per test and the chat. Managed execution means tests are built, checked, launched and read together with the DRIP team.

The difference in one line each: Shoplift answers how the page should look, Intelligems answers what the product should cost and come with, and Apex answers which test to run next.

03What Can You Test With Apex, Shoplift and Intelligems?

Where Intelligems goes further than the other two: offer, checkout and post-purchase tests. Price tests run through Shopify Functions, checkout scripts or duplicate products, and Intelligems says its team typically builds the price integration in “3-5 business days”.

Where Shoplift and Intelligems can do something Apex cannot: price tests. Price tests are not among the test types Apex documents, so if price testing is the main job, either app covers it and Apex does not.

Where Apex can do something neither app documents: A/A tests, a global holdout, feature flags and staged rollouts.

04How Do Tests Get Built and Launched?

Shoplift

Shoplift has no editor of its own. Variants are edited in the Shopify Theme Editor, or in Liquid or JavaScript. Before launch there is a preview mode and a QA checklist. A public API, pitched as “Command Your CRO Program From Claude or ChatGPT”, works over “plain HTTP”. We found no MCP server.

Intelligems

Intelligems has four editors: Visual Builder, AI Visual Builder, CSS/JavaScript, and JavaScript with an External API. Its Atlas Experience Agent builds content, theme, template, redirect and JS/CSS tests from a text prompt. The documentation is clear about the limit: “Offers, checkout, post-purchase, price, and shipping experience types are not yet supported.” Activation stays a manual step.

The Atlas QA agent checks the setup before launch, on all accounts. The Intelligems MCP server works with Claude, ChatGPT, Gemini and Grok; it can create, start, pause or end tests, and “Your AI client will ask you to confirm before running them.” White Glove Management is available on request.

Apex by DRIP

Apex keeps the experiment config as code and offers a code editor and a visual builder called Operator. CLI preview links and QA via preview let you check a variant before it goes live, and four QA checks are shown to clients: all devices, tracking and targeting, responsive, and matches design. An MCP connection lets a shop owner build and read tests from ChatGPT or Claude without a terminal; the CLI is the developer path. With managed execution, tests are built, checked, launched and read together with the DRIP team.

05How Does Each Tool Help You Choose Winning Tests Before Launch?

Ronny Kohavi puts the industry baseline win rate at 10 to 20 percent, so the order in which you test decides how much a program returns from the traffic you already pay for.

Apex: Likelihood to Win

Apex calls its method Prediction-Based Experimentation. In plain words: we know what shops like yours tested and which tests won. Every test idea gets a Likelihood to Win before launch, one percent figure per idea, shown with how many tests back it. The figure comes from the test memory: 4.3 million A/B tests from 151,000 shops, collected since 2011.

Does the ranking hold? In a holdout check, within a shop, the top third of ideas won 1.4 to 1.6 times as often (DRIP press release, September 29, 2026; vendor-stated). In early September 2026, predictions for 33 brands were scored and frozen; results are published from the launch on.

Intelligems: Smart Test Recommendations and Atlas

Intelligems’ Smart Test Recommendations (Beta) “analyzes your store’s performance and surfaces high-impact test ideas automatically”, as its Q1 2026 product recap puts it, and Atlas “ranks them by estimated profit impact”. Intelligems does not publish what data trains these recommendations, and we found no per-idea prediction shown with the number of tests behind it.

Shoplift: Lift Assist™

Shoplift describes Lift Assist™ as “Shoplift’s recommendation engine which dynamically provides theme sections”. On training data, Shoplift says it “analyzes millions of shopper sessions to recommend what converts” and “Leverages your brand and test ideas from hundreds of top brands”. We found no published win prediction per test idea.

06What Statistics Do They Use and What Gets Measured?

Shoplift uses “Bayesian statistical methods”, and its main metric is “Probability to Win”. As a guideline, Shoplift names “at least 10,000 visitors per variant and 14 days”. Metrics include revenue, orders, cart adds and revenue per visitor. We found no profit metrics, holdouts or automatic stops.

Intelligems uses “a Bayesian statistical model and Monte Carlo simulations”. Results show the probability to beat control and 95% intervals. The documentation recommends “300+ orders per test group” and “7+ days”. Metrics include revenue, profit and COGS per experiment and profit per visitor. Auto-stop and guardrails are not published.

Apex uses fixed-horizon statistics with confidence. Each test shows the main metric, lift and revenue over its runtime. On Shopify, Apex also reports profit per test: you can optimise for profit, with discount share, refund share and profit per sale. Guardian stops a test automatically when it crosses a revenue loss threshold.

If you sell with heavy discounts or high return rates, a variant can raise revenue and lower profit. That is the case for measuring profit per test.

Heat maps and behaviour

Apex shows heat maps and behaviour per variant: clicks, scroll depth, average fold and funnel steps. Shoplift has no native heat maps or recordings and integrates with Heatmap.com, Hotjar and Clarity. Intelligems offers Sitewide Analytics with a funnel view and connects to Microsoft Clarity, Heatmap.com and Hotjar; we found no heat maps of its own.

07What Do Apex, Shoplift and Intelligems Cost?

Shoplift pauses tests when a shop goes over its visitor limit. One conflict on its own site: the pricing page text shows Advanced monthly at “$299 /mo.”, while the page code and its September 2025 pricing update say $399.

Intelligems loads its tier table by script, so check intelligems.io/pricing for your own order volume. Bundles are 5 to 15 percent off and annual billing 20 percent off.

Apex does not publish its pricing. A card-free free tier for one store exists, and the way to a plan is to book a call. If your buying process needs a published price list before a conversation, both apps are easier to buy.

08Where Is the Data Hosted and How Is Compliance Handled?

Shoplift’s privacy policy says data “is transferred to and processed in the United States”. Shoplift acts as processor and the merchant as controller, under a DPA with EEA standard contractual clauses (Module 2) and the UK IDTA. We found no ISO 27001 or SOC 2 certification and no public subprocessor list.

Intelligems’ privacy policy states that data “will be transferred outside of Europe, including to Canada and the United States”. A hosting region is not published, and we found no DPA, subprocessors page, SOC 2 or ISO 27001.

Apex has GDPR in place and hosts in the EU plus UK, with DPAs for US tools. ISO 27001 and SOC 2 are in progress, not certified. Apex uses server-side tracking and first-party data, and supports the consent apps of most Shopify GDPR apps.

If your legal team requires EU hosting, that difference matters more than any feature row.

09When Are Shoplift or Intelligems the Better Choice?

Shoplift

• Your team works in the Shopify Theme Editor. Shoplift variants are edited there, with no separate editor to learn.
• You want to test prices in a single-currency store. Shoplift tests prices on Advanced and Pro, and subscription prices through Recharge 2.0. Price tests are not among the test types Apex documents.
• You need a published price and a trial before you talk to anyone. Shoplift publishes its plans from $99 a month and offers a 14-day trial on all plans (checked October 2026).

Intelligems

• Your testing plan is about what you charge and offer. Intelligems documents price tests per SKU, for subscriptions and across currencies, plus discounts, bundles, shipping rates, checkout blocks on Shopify Plus and post-purchase offers.
• You want more than two variants per test. Intelligems runs up to five groups per test. Shoplift “does not currently support A/B/n testing”.
• You buy on public reviews. Intelligems holds 4.8 from 198 reviews and Shoplift 4.9 from 133 on the Shopify App Store (checked October 2026). Apex has no public review profile yet.

If you are choosing between the two apps without Apex, our Shoplift vs Intelligems comparison goes through them head to head.

10When Is Apex the Better Choice?

• Your tests keep coming back flat. The constraint is choosing which tests to run, not building them. Every idea gets a Likelihood to Win from 4.3 million A/B tests from 151,000 shops before anything is built.
• You want to see why a variant won or lost. Apex shows profit per test on Shopify and heat maps and behaviour per variant, and Guardian stops a test automatically at a revenue loss threshold. Neither app documents heat maps of its own.
• You need EU hosting and want the program run with you. Apex hosts in the EU plus UK with GDPR in place. With managed execution, tests are built, checked, launched and read together with the DRIP team.

Apex is not the right choice for everyone. A team that already picks winning tests well gets less from the prediction layer. A shop that cannot ship a test a week yet should build that habit on a lighter tool first; buying prediction before you can execute is the wrong order. And anyone who needs a published price list before a conversation will not find one.

11Apex, Shoplift or Intelligems: Which Should You Choose?

If you already know which tests to run and want to ship them inside your Shopify theme at a published price, Shoplift is built for that. If the open questions are what to charge, what to offer and where to set shipping, Intelligems documents those tests in depth and reports profit per experiment. If your tests keep coming back flat, the constraint is choosing which tests to run, and Apex scores every idea before anything is built. If EU hosting or heat maps per variant are a requirement, Apex documents both and we found neither for the two apps.
