An AI size chart that answers each shopper's size question.

Genlook reads the size chart your store already has. Shoppers give their height, measurements or usual size, and get the size your chart points to, with the reason, right on the product page.

Which size should I take?

I'll check the Maison Rue size chart for this blazer. A few details first:

Height168 cm
Chest90 cm
Usually wearsM
Get my size

Size M. Your chest is 90 cm and the chart puts M at 88 to 92 cm. If you want room for a thick knit underneath, take L.

How long are the sleeves?And for the trousers?
Ask about the size

Maison Rue uses AI and can make mistakes.

  • Uses your own size chart
  • Talks about size only
  • Under your store's name

Size is the question shoppers ask most

Most product pages already link to a size chart. Shoppers still have to find it, measure themselves and work out which row is theirs, usually on a phone. In our shopping assistant pilot, size was the question shoppers typed most.

The chart sits behind a link

Few shoppers open it, and fewer read it to the end.

A table can't ask a question back

A chart lists every size for every measurement. It can't ask the one thing it needs, or tell a shopper which row is theirs.

Shoppers order two sizes and return one

This is called bracketing. The shopper tries both at home and sends one back, and the return usually costs you.

Your chart, read for one shopper at a time

The size chart stays yours. The assistant reads it, asks for what it needs, and tells the shopper which row is theirs.

  1. 1

    It reads your size chart

    From the size chart app you already use, your size guide page, or a chart published as an image. You don't rebuild anything.

  2. 2

    It asks only what the garment needs

    Height and chest for a blazer, waist and inseam for jeans, or the size they usually wear. Any field can be left blank.

  3. 3

    It replies with one size and why

    The reply names the size your chart points to and the measurement that decided it. Between two sizes, it says so.

It talks about size, and only size

The AI size chart is built to answer one question well. It doesn't sell, suggest other products or drift into other topics.

  • No product suggestionsIt never recommends other products. If a shopper asks about something else, it says it can only help with size.
  • No invented sizesWhen a product has no size chart, it says so. It doesn't guess, or convert from another brand's sizes.
  • Honest between two sizesWhen the shopper sits between two rows, it says how each size will feel and lets them choose.
  • Remembers the shopper's answersSaved on the shopper's own device, so the next product starts filled in. They confirm, never retype.
  • In the shopper's languageIt replies in the language the shopper writes in, in centimetres or inches.

What shoes would go with it?

I can only help with sizing here. For this blazer, tell me your height and chest and I'll check the size chart.

Find my size

Try-on shows the look. Your chart gives the size

Virtual try-on answers whether a piece suits the shopper. The size chart answers which size to order. Both live in the same Genlook window, so the shopper goes from one to the other without leaving the product page.

Size MYour chest is 90 cm and the chart puts M at 88 to 92 cm.
If the shopper agrees, the assistant can look at their try-on photo to judge their build, for that answer only.

Two assistants, in the same window as try-on

Both open inside the Genlook window on your product pages, under your store's name. Pick the size chart if size is the only question you want answered, and the shopping assistant if you want it to sell too.

When does it launch?
We open stores in batches, starting with Shopify stores that use Genlook. We have not set a date for everyone yet. Join the list and we will tell you which batch your store is in.
Do I need a size chart already?
Yes. The assistant answers from your chart: a size chart app, a size guide page or a chart image. When a product has none, it tells the shopper it can't give a size for it. If you need one, our free size chart generator builds it in a minute.
Does it guarantee the fit?
No. It tells the shopper which size your chart points to for their measurements, and why. Its answers are as accurate as your chart, and the shopper can always pick another size.
Will it recommend other products?
No. The AI size chart only answers size questions. If you want an assistant that also recommends products, builds outfits and answers store questions, that is the AI shopping assistant, which includes the size answers too.
Do I need Genlook virtual try-on?
Yes. The size chart runs inside the Genlook window on your product pages, next to virtual try-on. Shoppers can try a piece on and ask for their size in the same place.
Which platforms will it support?
It starts on Shopify. Tell us your platform on the waiting list form and we will let you know when it is supported.
What happens to the shopper's measurements?
Measurements are saved on the shopper's own device so they don't type them twice, and are used to answer the question they asked. See our Privacy Policy for the details.
