Now, ChatGPT can also help you buy products directly through chat, thanks to a new feature called Instant Checkout. US ChatGPT Plus, Pro and Free users can now purchase items from US-based Etsy sellers right within the chat. Currently, Instant Checkout supports buying one item at a time, but OpenAI plans to expand it to multi-item carts and more regions in the future. The technology behind Instant Checkout is called the Agentic Commerce Protocol. If a product supports Instant Checkout, you can simply tap “Buy,” confirm your order, shipping, and payment details, and complete the purchase without leaving the chat.
