ChatGPT App Builder for Ecommerce

Product discovery is changing. It entered into discussions.

In 2025, OpenAI positioned ChatGPT as more than just a chatbot, but as a comprehensive platform, with GPT-based applications, integrations, and a growing ecosystem where users actively explore products, services, and recommendations within the interface.

At the same time, firms like Gartner continue to highlight a clear shift: AI-driven collaboration is quickly becoming the primary link between brands and customers, not a secondary layer.

Here’s what that looks like in practice:

Consumers are no longer browsing first. They ask.

• “What should I wear to a garden party under €150?”
• “What’s with this sofa?”
• “What’s the best gift for someone with a small design?”

And platforms like ChatGPT are now built to respond to it.

For many brands, those conversations happen without them.

What are the applications of ChatGPT?

ChatGPT Apps are custom GPT-based experiences that reside within ChatGPT and are designed for specific use cases, including product discovery, recommendations, and guided shopping.

With the emergence of ChatGPT as a platform, OpenAI has made it possible for brands to build assistants that do more than just answer questions. These assistants can connect to existing systems, such as your product catalog, CRM, offers, and incentives. For ecommerce products, that means one thing:

You can create a seamless shopping experience within ChatGPT.

Instead of relying on generic responses, the ChatGPT App allows you to:

• More products from your catalog
• Use your own recommendation techniques
• Guide buyers through availability in a way that reflects your brand

If you want to explore how this integration works in detail, this ChatGPT Apps & Native Integrations breakdown explains how brands can connect their systems to ChatGPT environments.

Why ChatGPT is becoming a discovery channel

Moving from search to conversation isn’t just a UX change. It changes how purpose is held and where decisions are made.

In the traditional ecommerce journey, the goal is divided. The consumer types in a short query, applies filters, clicks on results, and gradually narrows down their options. Each step reveals a small part of what they want.

In ChatGPT, that process is compressed into a single interaction.

A consumer might say they need something for a garden party, under a certain budget, not too formal, and versatile enough to wear again. That level of detail doesn’t usually come up in a search query, but it’s what drives the buying decision.

This is what makes ChatGPT a very unique discovery layer. It captures intent directly, without forcing the user to translate it into keywords.

Discovery gap: products are not part of this collaboration

Despite this massive shift in the way consumers search and buy, many brands are not in these times of discovery.

When a buyer asks ChatGPT for a recommendation, the system does not have access to your catalog, your prices, or your sales strategy. It cannot use your recommendations or use your customer data to personalize the response.

The result is a standard response. Even if your product is as good as possible, it has no way to stand out.

This is not a ranking issue or a visibility issue. It is a structural gap.

Your brand is not connected to the place where the decision is made.

ChatGPT Apps solves this problem by allowing brands to build their own within ChatGPT.

By creating a GPT-based assistant, you can explain how acquisitions work, connect your product catalog, and guide consumers through branded information.

However, building that experience personally is not straightforward.

It requires rapid design, action schema configuration, backend integration, and a clear model of how discovery should work in all different scenarios. Personalization can add another layer, especially if customer data needs to be used in real time.

For many ecommerce teams, this is where the process breaks down. The opportunity is clear, but the process is more complex.

Introducing Insider One’s ChatGPT App Builder

ChatGPT App Builder is designed to remove that complexity.

It’s a no-code solution within Insider One that allows ecommerce teams to create, configure, and deploy a custom ChatGPT App using their existing infrastructure, with a simple step-by-step guided wizard.

Instead of building a ChatGPT App from scratch, teams use a guided workflow that translates their current availability setup into a ChatGPT-ready experience.

This includes:

• Configures how search and recommendations should work
• Links to the product catalog
• Using existing personalization logic
• Generates a ready-to-use ChatGPT Application package

Build your ChatGPT App in less than 30 minutes

The process is designed to be practical and quick.

Within Insider One, teams configure their ChatGPT App with a structured setup. They define their brand, choose acquisition capabilities, and decide how the assistant should respond to different types of customer intent.

What makes this approach different is that it builds on what already exists.

Capabilities like Smart Recommender and Eureka extend directly into the ChatGPT experience. Consumer data from our CDP is used to personalize communications, while supporting meaningful discovery of anonymous users.

Once configured, the system generates a ChatGPT application package that can be published immediately without additional development work.

After launch, discovery strategies can be updated at any time without needing to be rebuilt or rewritten.

Real-World Use Cases

Fashion: turning the intention into the perfect acquisition of goods

A consumer opens the ChatGPT App and describes what they need in one sentence: something for a garden party, under €150, not too formal, but versatile enough to wear again. Instead of returning generic suggestions, the brand’s GPT interprets the full context and responds with perfect combinations of clothes pulled directly from its catalog. It adapts recommendations based on budget, style, and occasion in real time, guiding the consumer to a confident decision.

For the buyer: Quick decisions with relevant recommendations, with a style similar to the real purpose, through the interface of ChatGPT that he likes.

For the product: Direct access to highly objective signals such as event, budget, and style captured in advance rather than defined later. That intent can feed back into recommendation strategies, sales decisions, and personalization in the future—feeding better personalization and sales.

Home and living: from single products to contextual spaces

A new home buyer asks a simple question: “What’s with this sofa?” ChatGPT App is not just the same products. Create context. It suggests complementary furniture, similar textures, and combined decoration options based on the concept of existing product recommendations.

So the experience feels less like browsing and more like guided design.

For the buyer: A guided experience that helps visualize the whole space, not just the individual elements, with contextual discussion to hone in on what will create the perfect space.

Brand: Rich first-party data on brand relationships, style preferences, developing marketing and acquisition strategies, and NPD.

Mobility: expressing the need through open-ended questions

A traveler asks: Where can I go to travel in the summer? Instead of static listings, GPT responds with curated campaign collections, seasonal offers, and relevant locations written in brand strategy. Discussion and recommendations are flexible, refined by budget, location, or travel style, without losing context.

For the buyer: Personalized options without having to search, filter, or restart the journey.

Brand: Early visibility into preferences, traveler type, demand patterns, enabling intelligent campaign planning and inventory targeting.

Anonymous consumers: capturing intent without identity

A new buyer without a profile comes to the ChatGPT app, following a recommendation from a friend. With little knowledge of the product or products, they describe exactly what they need. GPT extracts intent and returns relevant results using catalog attributes and context faster than a consumer could do on its own.,

For the buyer: Helpful, personalized recommendations without requiring a login, presented in a conversation that feels more personal and relevant than browsing a website.

Brand: Organized objective data from anonymous users, opening new signals for the first company to be targeted and exploited.
