Product preview with example data

Works with the stack you run

Works with Shopify, Shopify Plus, Meta Ads, Google Ads, Klaviyo, Claude, ChatGPT and Cursor.

We built an A/B testing app that counts the money

Most testing tools crown the variant with the best conversion rate. But a discount can win on conversions and still lose money once product costs, shipping and ad spend come out.

Convertify scores every test on gross margin per visitor: what each visitor actually earns you after costs. It runs on Shopify, builds variants on your real theme, and tells you in plain words which version to ship.

  • Winners picked by profit, not by clicks
  • A flat monthly fee, never a cut of your orders
  • An AI editor that works on your live theme

Every plan starts with a 7-day free trial, billed through Shopify.

The Convertify team

Built for Shopify brands that care about margin

Build a variant, let it collect real orders, and get a decision you can act on. Convertify handles the stats and the costs.

01

Build a variant on your real theme.

Describe the change and the AI editor makes it on a working copy, previewed with your real settings. Or set up a price, offer, shipping or template test in a few clicks.

AI editorYour live theme

Make the add-to-cart button sticky on scroll and raise the price contrast on mobile.

  1. Reading the product templatesections/main-product.liquid
  2. Locating the Add to cart block
  3. Pinning the button to a sticky bar on scroll
  4. Raising price contrast for mobilesnippets/price.liquid
  5. Rendering the variation with your theme settings

02

Measure every visitor, order and cost.

Orders, COGS, discounts, refunds, shipping and ad spend flow in from Shopify and your ad accounts, so each variant carries its true profit.

Decide with a verdict in plain words.

The chance each variant beats control, the likely profit lift with its range, a sample check, and one call: ship it, keep running, or stop.

A discount that lifts revenue can still lose money. Convertify scores every variant on gross margin per visitor: revenue minus COGS, discounts, refunds, shipping and the ad spend it took to get the visit.

Same test. Two ways to judge it.

Illustrative example. Judged on revenue, the discount looks like a 10% win.

Test the page, the theme, the price, the offer, the shipping and the checkout. Every test is judged the same way: by profit per visitor.

  • AI Edit

    Describe a change; the agent builds it on your real theme.

  • Template

    Pit two product, collection or landing templates against each other.

  • Theme

    Test a whole new theme against the one you run today.

  • Pricing

    Find the price that earns the most profit, subscriptions included.

  • Shipping

    Test free-shipping thresholds and rates without breaking checkout.

  • Offer

    Discounts, volume tiers, free gifts and free shipping, head to head.

  • Checkout

    Checkout blocks and upsells on Shopify Plus.

  • Split URL

    Send traffic to two different pages and compare what they earn.

The numbers tell you what happened. Heatmaps, replays and funnels show you why, so your next test is better than your last.

Heatmaps on clicks, scroll and taps, per variant.

Session replays with revenue on every visit.

Funnels that point at the leak worth fixing.

Connect Claude, ChatGPT or Cursor and ask. 79 tools let your assistant read funnels and heatmaps, build a variant, launch the test and read the verdict, scoped to your store over OAuth.

  • Draft and launch tests
  • Read results in plain words

77% of visitors never reach the cart. Heat shows thumbs stopping at the reviews, far below the button on mobile.

I made the add-to-cart bar sticky on mobile and launched Sticky add to cart at a 50/50 split. It will call a winner by profit per visitor.
