Aptis AI
Shopify App • Fitting & Return Defense Engine

Cut apparel returns. Protect your bottom line.

Size-related returns are the single largest drain on online apparel profits. Aptis AI evaluates customer height, weight, and key fit factors, cross-referencing them with historical sizing return patterns to deliver accurate recommendations that prevent returns before they happen.

The Engine Mechanism

How Aptis AI Cuts Returns

01 • EFFORTLESS INPUTS

Customer Profile

Shoppers never need measuring tapes. Directly on the product page, customers provide quick, top-of-mind metrics: height, weight, and key fit preferences (such as fitted, standard, or loose).

02 • INTELLIGENT AI MODEL

Historical Return Data

The AI model combines the shopper’s profile with your store's historical sizing return data, identifying real-world fit tendencies, cut discrepancies, and shrinkage factors that static charts miss.

03 • RECOVERED MARGIN

Lower Return Rates

Shoppers receive a high-confidence size recommendation before adding items to their cart. You prevent wrong-size orders, reduce return shipping expenses, and protect contribution margin.

Storefront Integration

Designed For Modern Shopify Merchants

Every return avoided is pure profit preserved. Rather than relying on generic size charts that cause buyer doubt, Aptis AI learns from what actually gets returned to provide accurate, real-world sizing guidance.
