Shopify & Artificial Intelligence

Shopify's AI is transforming ecommerce. We are your bridge to unlocking it.

Shopify has invested deeply in AI, embedding intelligence across the entire platform. From Sidekick, Shopify's AI business assistant, to Shopify Magic for automated content creation, AI-powered product imagery, agentic storefronts that put your products into ChatGPT and Microsoft Copilot conversations, and SimGym for simulating customer behaviour before you launch, the platform is evolving at pace.

Shopify's Winter 2026 Edition introduced over 150 new features with AI at the centre of every one. For merchants, this represents an extraordinary opportunity to save time, reduce costs and reach customers in entirely new ways.

Williams Commerce is the bridge between Shopify's rapidly evolving AI capability and the ecommerce businesses who want to realise its full potential.

Our team stays at the forefront of every Shopify release, ensuring our clients are not just aware of what is possible, but actively benefiting from it.

Talk to Our Team
Sidekick

Shopify's AI business assistant analyses your store data, builds custom apps via text command, creates Shopify Flow automations and delivers proactive trading recommendations via Sidekick Pulse.

Shopify Magic

AI-generated product descriptions, email subject lines, SEO-optimised content and studio-quality product image editing built directly into the platform. Scale your content without scaling your team.

Agentic Storefronts

Your products, brand voice and checkout experience appear directly inside AI conversations on ChatGPT, Perplexity and Microsoft Copilot, opening an entirely new sales channel.

SimGym

Simulate real customer behaviour before you launch. SimGym uses AI trained on billions of real commerce sessions to predict how shoppers will respond to changes in your store.

Tinker

Describe what you want and generate custom store themes, layouts and brand options without needing a designer for every iteration. Professional-quality design made accessible.

Rollouts & A/B Testing

Test theme changes and promotional variants in parallel, then let AI identify and deploy the best performing version. Native A/B testing that removes the need for costly third-party tools.
