AI Hand Scan
A guided hand photo, analysed by computer vision, becomes a ring size recommendation mapped to the brand's sizing system. No charts, no manual measuring.
Built for real conditions: any smartphone and any lighting.
Photo-based recommendation
A guided hand photo generates the recommendation.
Brand-specific sizing
Results map to the brand's EU, US, UK, or custom size format.
No special hardware
Shoppers only need a standard smartphone camera.
Ring Sizer
For gift buyers and shoppers with an existing ring.
Not every shopper measures their own finger. Gift buyers and shoppers with a well-fitting ring can use that ring as the reference instead so no hand photo needed.
Gift buying
Measure a ring the recipient already wears — no hand photo needed.
Existing ring reference
Use a well-fitting ring as the size reference.
Product-Aware Sizing
One catalog. Many sizing systems.
Different collections, materials, and product lines often follow different sizing rules. A single catalog-wide chart can't handle that.
Aitaca applies sizing logic per product or collection. Each item has its own size system, fit rules, and tolerance.
Product-level sizing
Configure each product or collection with its own sizing system. EU, US, UK, or custom.
More accurate recommendations
Recommendations adapt to the specific product, not a catalog-wide mapping.
Embedded Add-to-Cart Flow
From sizing to cart in one step.
Every extra step after sizing is a chance to drop off. Aitaca lets shoppers add the recommended size to cart directly from the widget. No redirects, no backtracking.
Sizing to cart in one flow
Recommendation and add-to-cart happen in the same place.
Less drop-off after sizing
No extra steps between finding the right size and buying.
Clear conversion impact
With sizing tied directly to add-to-cart, brands can measure exactly how sizing affects conversion.
Stock-Aware Recommendation
Right size first. Best available second.
When the ideal size is out of stock, Aitaca surfaces the best available alternative but only when fit logic allows it.
This is not a tool to push whatever is in stock. If the nearest available size falls outside acceptable return-risk tolerance, Aitaca won't substitute. A recovered sale isn't worth a costly return.
Fit comes first
Fit accuracy is evaluated first; stock is a secondary input. Aitaca only adapts when the outcome stays commercially safe.
Safe alternatives only
If adapting to stock would breach fit tolerance, no substitution happens. Return rates stay protected even when inventory is tight.
Recover sales without pushing wrong sizes
When the tradeoff is safe, the shopper is guided to the best available size, converting a session that would otherwise end empty, without lifting return risk.
Alternative Product Recommendations
Keep shoppers in the journey.
When the recommended size isn't available for the chosen product, the default outcome is a lost sale at one of the highest-intent moments in the journey.
Aitaca recovers that intent by surfacing catalog alternatives that fit the shopper's recommended size, keeping them inside the brand's experience instead of out the door.
Size-based alternatives
Alternatives are filtered by recommended size, not by style tags or manual curation.
Keeps shoppers in the journey
Suggestions surface inside the sizing flow, before the shopper drops off.
Connected to the catalogue
Aitaca ties the size recommendation to the brand's catalog, surfacing products that include the shopper's size.
Demand Analytics
Real sizing data. Not a proxy.
Every sizing session is a real measurement. Aggregated, these become a demand map for purchasing, planning, and range decisions. The kind of sizing intelligence that used to exist only in physical retail.
Instead of relying only on sales or returns, brands can see real size demand from shoppers who used the sizing flow.
Size demand distribution
The real distribution of measured sizes across your shoppers. Direct measurement data, not a proxy from sales or returns.
Product and collection insights
Which products generate the most sizing uncertainty, which collections drop off most at the sizing step, and where behavior signals a structural fit problem.
Demand by market
Size demand varies by geography. Aitaca surfaces market-level differences so merchandising can make region-specific range and stocking decisions.
