AI Size & Fit Assistant

Size doubt shouldn't
get in the way of the purchase

NeaFit is an AI size & fit assistant that installs on product pages with a single line of script. Shoppers enter their height and weight; it recommends a size from the garment's real measurements and answers fit questions in a chat.

Problem

A wrong size costs more
than return shipping

Size is a common hesitation in online fashion. A size return means support time, inventory stuck in transit, and a customer who may not come back.

Round-trip shipping

Size returns leave shipping disputes and handling costs behind.

The same question, daily

“I'm 5′4″ — will M fit?” The hours spent answering add up.

Tied-up inventory

While a return travels, that piece can't sell. Inspection and restocking take hands too.

Intro Film

NeaFit in one minute

The problem, the fix, and how it works, in short.

Features

One widget, three jobs

Confidence for shoppers, fewer repeat questions for your team.

Size picks

Reads the size table on your product page and compares the garment's measurements with the shopper's height and weight.

AI size chat

Answers fit questions on the product page and hands the ones it can't answer to your team.

Fit guide

Your brand's fit notes, written once in the admin, apply to every pick and answer.

How It Works

How shoppers use it

No sign-up, and they never leave the product page.

1Enter height and weight

Feet, inches and pounds, or centimeters and kilograms. Saving go-to garments makes later picks sharper.

2AI checks this product's specs

It reads the size chart and compares shoulder, chest and length.

3Choose with confidence

Fit notes per size make the choice clear. Between two sizes, it asks about fit preference.

Impact

What NeaFit is built to change

Size questions and size-related returns are a steady cost in fashion e-commerce. NeaFit is built to take them on.

Fewer repeat size tickets

The AI handles the routine questions; the hard ones reach your team.

Built to reduce size returns

Picks come from the garment's measurements, not a generic size chart.

Help shoppers decide

FAQ

Frequently asked questions

Which platforms does it support
We test on Shopify Online Store 2.0 themes. NeaFit is a script, not a platform-locked app, so WooCommerce, BigCommerce and custom storefronts can work too: email us at hello@neafit.xyz and we'll help you install.
Where does NeaFit get our size chart
It reads the size table on your product page automatically. If your chart is an image or comes from a size-chart app, email it to hello@neafit.xyz (a link, a CSV or a screenshot) and we'll set it up for you.
How is shopper data handled
No account is required for shoppers. Height and weight are used only for size picks and are never sold. Your team sees them in the admin's conversation logs, under an anonymous ID and never with a name or email, so you can answer size questions. Body measurements a shopper enters are deleted 12 months after their last activity. Data is stored in Korea; AI processing happens in the US. Shoppers have rights under CCPA/CPRA. See our privacy policy for details.
Is the widget accessible
Keyboard navigable; we're working toward WCAG 2.1 AA.
What are your support hours
Our team works Korea Standard Time (KST). Email us at hello@neafit.xyz and we'll reply within one business day (Korea time, Mon–Fri).
