What is Constructor.io AI?
Constructor is an AI product discovery platform specialising in the search and browse experience on large e-commerce sites — personalising search results, autocomplete suggestions, category page product ordering, and recommendations for each individual shopper based on their behaviour and intent.
Search personalisation is Constructor's primary capability. When a shopper searches for 'running shoes', Constructor's AI ranks results differently for someone who has previously bought premium performance gear versus someone who typically buys sale items. The results show the products most likely to convert for that specific shopper rather than the same generic ranking for everyone.
The ranking models are trained on the retailer's own transaction data — clicks, add-to-carts, purchases — and continuously updated as new transactions occur. The model learns which products convert for which shopper types across the category, improving personalisation with each new data point.
Browse personalisation sorts category pages differently for each visitor based on the same behavioural signals — a product that is bestselling overall may rank lower for a shopper who has only ever bought from specific brands or price tiers.
AI-powered autocomplete surfaces personalised suggestions as shoppers type, showing relevant products and categories earlier in the search experience and reducing the path from intent to product page.
At enterprise scale, Constructor works with major retail clients including Sephora, Ulta, and Petco where search is a significant revenue driver and personalisation impacts are measurable at scale.
How Constructor.io AI works
Constructor.io AI runs as ml platform software built around data workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web, ios, and android, with API access for teams that want to embed it into their own products.
