ZeDaq.ai vs Virtusize: Size Comparison Tools Compared

ZeDaq.ai and Virtusize both help shoppers pick a size, but they start from different inputs. ZeDaq.ai sizes shoppers from a photo plus height against your own size chart and adds photo try-on, while Virtusize builds recommendations from its fit profiles and the size data a brand uploads.

The Virtusize site says "shoppers get their size in under 30 seconds." It says every recommendation is personal and built from "250,000+ fit profiles." The page didn't list the exact questions shoppers answer.

For brands, the homepage says size data can be uploaded as CSV, Excel or PDF. It says "our AI converts it to the Virtusize standard automatically."

Which platforms does Virtusize support?

The Virtusize homepage mentions "two simple script tags" and names Shopify, Magento, WooCommerce, Salesforce Commerce Cloud, BigCommerce and custom or headless setups. It also links to a Shopify app.

What does ZeDaq.ai offer?

ZeDaq.ai offers AI virtual try-on and Find my size sizing for fashion stores, plus tools for tailors and designers.

How does ZeDaq.ai recommend a size?

The shopper taps Find my size, uploads one photo and enters their height. A 30-second body scan estimates their measurements and matches them to your own size chart for that garment type.

You enter charts in Dashboard → Size charts, or in the Shopify app, one per garment type: tops, outerwear, dresses and bottoms. When measurements point to different sizes, the scan recommends the size that fits the largest relevant measurement. Without a chart, it uses a generic UK, US, EU or AU chart.

Does ZeDaq.ai include try-on?

Yes. The same widget includes Try it on, where the shopper uploads one photo and sees your real garment on their body. ZeDaq.ai also offers live-camera eyewear try-on.

Which platforms does ZeDaq.ai support?

• Shopify, through the ZeDaq.ai Shopify app.
• WooCommerce, Wix, Squarespace, BigCommerce and custom sites, through one script tag with a key locked to your domain.
• Custom interfaces, through the REST API with POST /api/v1/tryon and an x-api-key header.

How do the two pricing models differ in practice?

The pricing models reward different situations, so it helps to think them through before you compare numbers.

Flat plans

With a flat monthly plan, you know the bill in advance. That makes budgeting simple, especially for a small team. The trade-off is that you choose a plan level and need to move up if your usage grows.

Pricing tied to outcomes

The Virtusize homepage says its core pricing is tied to Virtusize-assisted conversions. A model like that moves with your sales. Ask how an "assisted conversion" is defined and how it is counted, so you can estimate your monthly cost.

For Shopify stores, Virtusize also lists a separate monthly price, which may be easier to compare with flat plans.

Which tool suits which store?

When might ZeDaq.ai suit you?

• You want shoppers sized against the exact labels on your own chart.
• You want try-on and sizing in the same widget.
• You want flat, published prices and a free plan to test with.
• You sell eyewear as well as clothing.
• You also run a made-to-order business and want client records and invoices.

When might Virtusize suit you?

• You want visual size charts as a separate product.
• You already have size data in spreadsheets or PDFs and want it converted.
• You want fit data to feed your marketing and product systems.
• You prefer pricing that moves with assisted sales on the core product.

Our comparison of ZeDaq.ai and Sizebay covers another size tool, and the comparison with Genlook for try-on covers a try-on-first app.

How should you test both on your store?

Run the same test on each tool, with the same people and products.

1. Pick five products that get the most size questions.
2. Choose four testers whose correct size you already know in each.
3. Run each tester through each tool on a phone.
4. Record the size each tool suggests next to the correct size.
5. Note what the shopper had to do, step by step.
6. Estimate your monthly cost at your current traffic on each pricing model.

With ZeDaq.ai, the Free plan covers a small test, and a paid plan's 3-day trial covers a larger one. For Virtusize for Shopify, its homepage lists a low-cost first month.

What work does each tool need from your team?

Setup effort often decides which tool actually goes live, so compare it as carefully as features.

Preparing your size data

With ZeDaq.ai, you type your body-measurement ranges into a chart for each garment type. A small brand with four garment types can usually do this from its existing size guide. The key is to use body measurements, not flat garment widths, and to make the ranges meet without gaps.

With Virtusize, its homepage says you upload size data as CSV, Excel or PDF and its AI converts it. If your size data already lives in spreadsheets, that may save typing. Ask what format works best and who checks the converted result.

Adding it to your pages

Both tools use script tags on non-Shopify sites, according to each company's pages. On Shopify, ZeDaq.ai uses an app embed you switch on in the Theme Editor.

Keeping it current

New products need size data in both tools. Decide who on your team owns that job before launch, so new arrivals don't go live without a recommendation.

What should you ask before you decide?

Send both vendors the same short list:

1. What does the shopper see and do, step by step, on a phone?
2. What happens when a product has no size data yet?
3. Who checks that recommendations match our own fitting judgment?
4. What will we pay at our current traffic, and at double it?
5. How do we remove the tool, and what happens to our data?

Clear written answers make the final choice much easier.
