Overview
Stellagent today announced the launch of Omise AI, a development service that enables EC businesses to open their own dedicated shop apps within ChatGPT, effective December 17, 2025. This service allows businesses to establish a new sales channel reaching ChatGPT's 800 million weekly users.
Background
Traditional EC customer acquisition has centered on search engines and social media advertising. In recent years, however, consumer purchasing behavior has shifted significantly. More consumers now go through a consultation phase -- asking "What should I choose?" or "What product suits me?" -- before making a purchase. Conversational AI interfaces like ChatGPT have emerged as a new channel capable of naturally engaging consumers during this consultation stage.
However, implementing apps on ChatGPT requires advanced expertise including compliance with the Agentic Commerce Protocol (ACP) and API development, presenting a significant barrier for many EC businesses. We developed Omise AI as a development service specializing in the retail and EC domain to address this challenge.
Three Key Advantages
1. Customer Engagement at the Consultation Stage
Customer acquisition through search engines and social media typically reaches consumers only after they have already formed purchase intent. Omise AI establishes customer touchpoints from the early "consultation" stage on ChatGPT, designing a consistent path from initial inquiry through to purchase.
2. Seamless Purchasing Experience
In conventional EC, multiple page transitions are required from product search to cart addition and payment completion. Omise AI delivers a seamless experience from product recommendation to purchase completion within ChatGPT conversations, reducing drop-off throughout the purchasing process.
3. No Technical Expertise Required
We handle all technical aspects required for app development on ChatGPT. EC businesses can set up and operate their AI store without any technical knowledge.
