Tilly vs Intelligems

Intelligems tests the numbers that decide your margin, such as prices, shipping, offers and checkout, and reports the profit on every test.

Pick Intelligems if your open question is what to charge and you have the traffic to test it. Pick Tilly if the question is what to say. Tilly reads your pages and reviews, finds what stops your buyers, writes the fix and the test variants, sizes each test and calls the winner from your results, while a testing app such as Intelligems splits the traffic. What wins on your pages goes into your emails and ads too. Try the free audit: paste your store URL and see in about a minute what Tilly would fix first.

Intelligems is a Shopify testing app for prices, content, shipping, checkout and post-purchase offers, rated 4.8 out of 5 on its listing. source, checked 25 September 2026

It reports revenue, profit and cost of goods on every test, so you see what a change earned, not only its conversion rate. It personalises by traffic source, device, Klaviyo segment or behaviour, and its AI finds ideas, builds tests and reads results in Claude and Slack.

Each app’s cells come from its own Shopify listing or pricing page, linked beside the words. “Not listed” means we did not find it there, not that the app cannot do it. Tilly’s column is our own product.

Intelligems' figures come from its Shopify App Store listing and pricing page, each cell linked and dated. Its pricing scales with sitewide order volume, so the figures shown are the published starting prices.

On its Shopify listing, Intelligems' Smart Content plan starts at $69 a month, Smart Merchandise at $112.10, and Unlimited at $349, all scaling with sitewide order volume, with a 14-day free trial.

Tilly charges per test rather than by order volume: 10 credits for an A/B test including writing the variants, from a Store plan of $49 a month for 500 credits after 100 free credits. A CRO audit is 20 credits and each written fix 10.

At low order volume the two cost a similar amount to start. As orders grow, Intelligems' price grows with them; Tilly's does not, but it also does not test prices or shipping at all.

The last table prices the same store on both. These apps price by visitors, orders or tested users, so check each calculator for your store. Tilly does not split traffic: it plans the tests, writes the changes and calls the winner, next to a testing app rather than instead of one.

This page is Tilly's, so Intelligems' strengths go first. On pricing experiments, it does what Tilly does not attempt. source, checked 25 September 2026

• Price, discount, shipping, checkout and post-purchase offer tests. Tilly does not test prices or shipping.
• Profit, not just conversion: revenue, profit and cost of goods side by side on every experiment.
• Personalisation by traffic source, device, Klaviyo segment or behaviour, so a winning variant can be rolled out to the audience it won for.
• A strong public record on Shopify: a 4.8 rating when we checked.

Tilly writes the tests. Every other agent feeds the experiments backlog: the CRO agent finds a page that does not answer an objection, the ads agent sees one angle beating another, the email agent sees one email carrying a flow. Each idea arrives as a hypothesis tied to a persona and a worry, with the variants already written.

It learns from your own results. Every night it reads what each email, ad, post and page change earned, keeps the patterns your numbers back up, and writes the next piece with them, so a winning ad angle can become an email subject line and a product-page headline. Intelligems tells you which price or offer won; Tilly takes a winning message from one channel and writes it into the others. (How the loop works.)

It also watches two things most marketing tools miss: whether AI assistants name your store when asked your buyers' questions, the part of search now called AEO (how to get named by ChatGPT), and every change made to your theme, products, pages and menus, with what each said before and after.

It tests beyond the storefront. Subject lines, content, offers and send times in Klaviyo, and creative, angle and hook in Meta, are tested the same way as page copy, from one place.

It calls winners carefully. A minimum sample before any call, a maximum run time, one primary metric chosen up front, and a plain-language result. If a test does not reach enough data, Tilly says so rather than picking a winner by chance.

Results teach the other agents. A finished test is written into your brand profile, so the next email, ad or page fix reads it.

It starts with free diagnosis. The store audit is free and the CRO audit is 20 credits, so a store can see what Tilly would change, and why, before any test is set up or any traffic is split.

These rarely replace each other. A store can keep Intelligems for price and shipping tests and use Tilly for email, ad and copy tests; they touch different parts of the business.

If you are moving page tests from Intelligems to Tilly, finish or stop running experiments first so no shopper sees a half-ended variant, and note the winners you rolled out, because Tilly will not know about them unless you tell it.

Run Tilly's free audit, then a CRO audit on your key product page. The fixes it writes arrive on a preview copy of your theme; the bigger ones go to the experiments agent as tests with the hypothesis already written.

Keep price tests with a tool built for them. Tilly will not change prices, and it should not be the reason you stop learning what your customers will pay.

Give each tool the tests it is best at for a quarter, then compare what you learned. A store that knows its best price and its best product-page copy is in a better place than one that ran twice as many tests on either alone.
