Integration details

Description

Penny in ChatGPT helps you find great products and keep tabs on prices - without leaving the chat. Tell Penny what you’re shopping for (or upload a photo to find similar items), browse options, and ask questions to choose the right one. When you find something you like, Penny can start price tracking so you’ll know if the price changes. For example, try: “Penny, find cool funky socks,” “Penny, find shoes like this” (with an image), or “Penny, start price tracking the jacket I liked best.”

Penny FAQ

How do I improve a ChatGPT Plugin's discoverability?

The levers are the listing surface agents actually read: names, descriptions, keywords, tool metadata, and registry health. Which lever matters depends on where discovery breaks, which is what continuous measurement shows.
