AI SIZE CHART · WAITING LIST

The size chart that knows the shopper.

Genlook learns the garment from your catalog, and the shopper from a photo, the brands they wear, and what they kept before. Then it says the one thing a table never could: your size is M.

We open stores in batches. Send your store URL and we will tell you which batch you are in.

01 · The gap

A table has never picked anyone's size.

Most product pages already have a size chart. Shoppers still order two sizes. A table hands the shopper homework: measure yourself, convert the units, guess how much room the cut leaves. On a phone, with a cart open, nobody does the homework.

What bracketing costs →

The chart is not the problemYou probably publish one already. It sits behind a link, opened by few, trusted by fewer.

Measuring is the problemCharts are written for people who already know their numbers. Between the shopper and their size stands a tape measure they do not own.

So they order twoThe fitting room moves into their bedroom, and one size rides back at your expense.

02 · Where it lives

The answer sits on the size row.

No popup to find, no chart page to open. The recommendation appears where the decision happens, above add to cart, in your theme's own type.

Your theme, your type

One install, no theme code. The answer inherits your storefront's styling.

Your brand, not ours

White-label: the size finder carries your store's name, not Genlook's.

03 · How it knows

It reads the shopper, not just the garment.

The size finder works with whatever the shopper is willing to give. The first signal is usually enough, and every one after it sharpens the same answer.

PHOTOFrom their photoThe photo they upload for a try-on already carries their build: shoulders against torso, where the waist sits. Enough to place them on a garment chart without a single number.

WARDROBEFrom what they already wearA size that fits them in a brand we recognise anchors the estimate to a real garment instead of a population average. One dropdown, no homework.

ORDERSFrom your order historyWhat this shopper kept, and what came back. The answer sharpens the longer they shop with you, and none of it leaves your store.

FITFrom how they want it to sitClose, regular, or oversized. The same body takes a different size depending on the answer, and a garment chart knows exactly how much room each cut gives.

TAPEFrom measurements, if offeredWelcome, used, never required. The tape measure is the fifth signal, not the front door.

ANSWER

✳ Her size: MThis cut runs large, so M rather than her usual L. Five signals in, one size out.

04 · The answer

One size. And the why.

A recommendation the shopper cannot interrogate is a recommendation they will not trust. Genlook shows its reasoning in a sentence, so the shopper can overrule it the one time they know better.

A size, stated plainlyNot a range, not a table to interpret. The size to put in the cart.

The reason, in one line"This cut runs large, so M rather than your usual L."

A call on the close onesWhen it sits between two sizes it says so, and which way to lean for the fit they asked for.

The honesty to abstainA thin product page gets a careful answer, not a confident wrong one. A size tool gets one bad guess before the shopper stops listening.

05 · Underneath

The chart writes itself.

Every recommendation needs real measurements to reason against. Genlook builds a garment-specific chart for each product from the catalog you already publish.

Per product, not per brand

Two cuts sharing a label size get two different charts. That difference is where returns are born.

Built from what you publish

Titles, descriptions, variant options, supplier sheets, photos. Nothing new to write.

Yours to correct

Change one number and every recommendation built on it moves. The chart stays for shoppers who like to read.

06 · Alongside try-on

One photo. Two questions answered.

Try-on answers whether the piece suits them. The size finder answers which one to order. Same upload, same consent, and the two doubts that hold a purchase back are gone.

07 · Your stack

It goes where your catalog already is.

The size finder runs on the same store platform as the rest of Genlook. If we can read your catalog, we can build the chart and answer on it, whatever you sell on.

FAQ

Waiting list questions, answered.

Everything else is in the docs, or ask us directly at hello@genlook.app.

When does it launch?

We are opening stores in batches rather than all at once, so recommendations get checked against real catalogs and real returns before they go wide. Join the list and we will tell you which batch your store is in.

Is this a size chart app for Shopify?

Yes, and not only Shopify. It runs as a size chart app on Shopify, WooCommerce, PrestaShop, Shopline, BigCommerce, Magento and Wix, and through an API on custom storefronts. The waiting list form takes any platform.

How is this different from a size chart generator?

A generator gives you a static table to paste on the page; our free size chart generator does exactly that. This product goes further: it builds a garment-specific chart for every product automatically, then works as a fit finder, recommending each shopper one size with the reason.

Does the shopper have to upload a photo?

No. A photo is one signal among five, and the strongest one is usually a size they already own in a brand we recognise. Shoppers who uploaded a photo for a try-on can have it reused, with their consent, instead of doing anything twice.

How accurate can it be without measurements?

Accurate enough to beat a shopper guessing, which is the benchmark that decides whether anything comes back in the mail. It leans on the signals it has, states how confident it is, and abstains when a product page is too thin to answer well.

What if a recommendation is wrong?

The shopper can always overrule it, and the reason is shown so they can tell when to. On your side, correcting a garment's measurements moves every recommendation built on it, and returns feed back into the estimate.

Do I need the virtual try-on app to use it?

No. The size finder runs on its own. If you already use Genlook try-on, the two share the same photo, the same consent and the same dashboard.

What happens to shopper photos and data?

Photos are processed to estimate proportions and are covered by the same retention and consent rules as try-on: encrypted, auto-deleted, never used to train models. Order history stays in your store. See our Privacy Policy for the details.
