Battle-test AI coding models side by side
Send the same coding prompt to multiple leading models and compare their generated apps and logic side by side.
Watch models construct web apps and websites live, so you can see process and output, not just the final file.
Projects go beyond one-off snippets, testing how well a model structures components, routes, and styles together.
Track which coding models accumulate the most wins over time to identify consistently strong performers.

Autonomous personalisation that predicts what each customer will buy next
Decisions about what each customer should see next are made by the system per individual, not by segments, campaigns or predefined journeys.
Live data on transactions, product variants and browsing velocity is synthesised to surface products a shopper has not yet shown obvious interest in.
The engine aims to identify when buying intent for a given customer is strongest, rather than following a fixed send schedule.
Contacts customers after they leave the site, when their preferences have continued to evolve away from any session context.
