Size Finder Lite - Now Available on Shopify App Store - Free

Back-in-Stock Alerts with Clothing Size Finder Technology

Prime AI takes back-in-stock alerts to the next level by combining product availability with personalised size recommendations.

When a shopper views a product that’s out of stock in their size, Prime AI’s Clothing Size Finder doesn’t just stop at suggesting the right fit—it offers the shopper the option to receive a notification specifically for their recommended size.

A smarter alert system:

This creates a more relevant, shopper-centric experience that:

  • Only notifies customers when their correct size is back in stock

  • Eliminates frustration caused by generic restock emails

  • Increases conversion by re-engaging high-intent shoppers at just the right moment

Flexible integration:

Alerts can be triggered via email directly from Prime AI, or fully integrated with your existing systems – whether that’s your ESP, SMS platform, or in-app messaging provider. This makes it easy to align with your communication strategy while recovering lost sales.

Why it matters

Generic restock alerts don’t work when the item still isn’t available in the shopper’s size. Prime AI’s solution is different – it’s fit-aware, timely, and built to convert.

By offering personalised back-in-stock alerts based on fit, you build shopper trust, improve satisfaction, and win back sales that would otherwise be lost.

Handy tool and fantastic customer service
The tool allows us to offer accurate fitting information to our customers, including information based on returns to maintain accuracy. The Prime AI team are very helpful if/when issues arise, and are quick at responding and solving problems, as well as suggesting new ways the tool can be implemented.

Efficient Cooperation
Our cooperation with Prime AI is very successful, we are happy with the results. Also, optimisation of the tool has been implemented after multiple feedback sessions to which Prime AI has been very open. The UX was not the best, but after multiple feedback sessions, things got fixed.

Great software and amazing account management
Prime AI's account management and monthly reports/ recommendations have been brilliant. We have been able to customise the platform to suit our needs and no ask is ever too much 🙂 ...
