Shopify AI Apps for Fashion Stores Worth Testing

The Shopify AI apps for fashion stores most worth testing are the ones that answer a shopper's two biggest questions: "how will this look on me?" and "which size should I buy?" ZeDaq.ai, GenLook, Kiwi Sizing, Virtusize and True Fit each tackle one or both, with very different prices and setup.

This guide focuses on fit and try-on apps, because those questions sit right on the product page where buying decisions happen. For a ranked list of try-on apps only, see the best AI virtual try-on apps for Shopify.

What makes an AI app worth testing in a fashion store?

Not every AI app earns a place on your product page. Before you install anything, check it against these points:

• It solves a problem shoppers already have. Fit doubts and "will this suit me?" are common in clothing.
• It has a free plan or trial. You should be able to test on real products before paying.
• It's quick to remove. If it doesn't help, you can switch it off without leftover code.
• It works on mobile. Most fashion browsing happens on a phone, so test there first.
• Its pricing scales sensibly. Check what happens to your bill if traffic doubles.

What does each app actually do?

ZeDaq.ai: try-on and sizing in one widget

ZeDaq.ai adds a "Try it on" button to product pages. The shopper uploads one photo and sees your real garment on their body. Inside the same window, "Find my size" runs a 30-second scan from one photo plus height and suggests a size from the chart you enter, one per garment type.

Setup is an install, a size chart and switching on the app embed in your theme. The Free plan is $0 with 3 try-ons, 3 measurements and 5 invoices a month. Paid plans are Micro at $14 a month, Starter at $49, Growth at $129 and Scale at $299, each with a 3-day free trial and no card required.

GenLook: try-on with an optional size assistant

GenLook adds a try-on button so shoppers see your clothes on themselves, per its Shopify App Store listing. The listing shows a 5.0 rating from 41 reviews.

Its plans are Free with 10 try-ons a month, Starter at $19.99 for 100, Growth at $29 for 300 and Pro at $79 for 1,000. Growth and Pro add an AI size assistant marked beta and remove GenLook branding.

Kiwi Sizing: AI-assisted size charts

Kiwi Size Chart & Recommender adds size charts, size guides and fit recommendations, according to its App Store listing, which shows a 4.7 rating from 1,242 reviews.

The Free plan publishes up to 3 size charts with a watermark. Premium is $7.99 a month, Plus is $14.99 and Ultimate is $26.99, each with a 14-day free trial. The listing notes extra charges based on order volume on Plus and Ultimate.

Virtusize: fit-profile size recommendations

Virtusize recommends sizes from fit profiles. Its pricing page lists Virtusize for Shopify at $1 for the first month, then from $39 a month, described as a simple plug-in for Shopify stores. A larger Core plan uses pricing tied to Virtusize-assisted conversions.

True Fit: enterprise fit guidance

True Fit offers fit guidance built on purchase and return data, an AI shopping agent and virtual try-on, per True Fit's website. The site mentions a Shopify integration and says its shopping agent is Shopify Plus Certified. It lists no prices and asks you to book a demo, so it suits larger stores.

Which app fits which kind of store?

Match the app to the problem you see most often in your store:

• Shoppers ask "will this suit me?" Start with a try-on app such as ZeDaq.ai or GenLook.
• Shoppers ask "which size?" Start with a sizing tool such as Kiwi Sizing, Virtusize or ZeDaq.ai's "Find my size".
• Shoppers ask both. One widget that covers both, such as ZeDaq.ai, keeps the product page simpler.
• You run a large catalog with an integration team. An enterprise vendor such as True Fit may be worth a demo.
• You sell made-to-measure as well. ZeDaq.ai also includes tools for tailors, such as client records and measurement links.

If you aren't sure which question comes up most, read your last month of support messages and count them.

How do you compare costs fairly?

App prices look simple until you map them to your traffic. Use this method.

1. Estimate monthly product-page visitors from your Shopify analytics.
2. Guess how many will use the feature. Start low, since not every visitor taps a button.
3. Check each app's unit. Some count try-ons, some count scans, some count size charts or orders.
4. Price the plan that covers that usage, including any overage or order-volume fees.
5. Recheck after one month using real usage numbers from the app.

Our guide to try-on app pricing on Shopify explains how renders and scans are usually counted. To see what you can learn before paying, read what you get on a free try-on plan.

How should you run a two-week test?

A short, structured test beats leaving an app running and hoping.

Week 1: set up and check quality

• Install one app at a time on a duplicate theme.
• Add your size charts where the app uses them.
• Test five products on your own phone and with two or three friends.
• Fix anything that looks off before going live.

Week 2: watch real shoppers

• Publish to your live theme.
• Track how many shoppers open the feature.
• Read support messages for fit questions.
• Note any complaints about speed or layout.

At the end, keep the app only if shoppers use it and it fits your budget. AI apps work alongside a clear returns policy, not instead of one. Our ideas for returns policies that protect margins cover the other half.

FAQs

Can I run a try-on app and a size chart app together?

Usually yes, but test on a duplicate theme first so buttons don't clash. If one app does both, you may not need two.

Do these apps slow down my product pages?

Any app adds some code. Test page speed before and after installing, and remove apps you don't use.

Which app has the cheapest paid plan?

Of the apps listed here, Kiwi Sizing's Premium plan at $7.99 a month is the lowest paid price, per its listing. ZeDaq.ai's lowest paid plan is Micro at $14 a month.

Do shoppers need to download an app?

No. All of these run on your own product pages. ZeDaq.ai's only app is ZeDaq Business, which is for tailors.
