Show HN: Commerce GPT – Chat with LLMs to find products in your store (opens in new tab)

I’ve been experimenting with blending AI chat into e-commerce workflows. Commerce GPT is a proof-of-concept for a quick "quake-style" chat window that adds AI-powered search to your store.

Why? Typing (or speaking) multi-criteria queries to find products to buy can be faster and more intuitive than navigating menus, e.g. searching for “yellow bag under $100” or "extra virgin olive oil with high polyphenol count over 400 mg"

Built with Next.js + AI SDK and in the demo it integrates with OpenAI GPT-4o to process product data (thanks to AI SDK switching providers is straightforward)

It's still a work-in-progress, but I'd love your feedback! Could this be useful? What features or improvements would you like to see?
