ChatGPT Becomes an App Platform as OpenAI Rolls Out Developer SDK

Think ChatGPT is nothing more than a handy tool? Think again. 

OpenAI has unveiled a new generation of apps that live inside ChatGPT, marking a major step toward making the AI model a hub for productivity, creativity, and services.

Alongside the rollout, developers can start building their own interactive experiences through the new Apps SDK, now in preview.

The system now allows users to summon apps naturally during a chat just by typing prompts like "Spotify, make a playlist for my party" or "Zillow, find me a two-bedroom near Austin."

Apps respond conversationally while adding visual elements like maps, slides, or playlists directly in the interface.

“Apps in ChatGPT fit naturally into conversation,” OpenAI said in its announcement.

“For ChatGPT users, apps meet you in the chat and adapt to your context to help you create, learn, and do more.”

Early pilot partners include platforms such as Booking.com, Canva, Coursera, Expedia, Figma, Spotify, and Zillow.

Notably, all of them are integrated for English-speaking users outside the EU.

For developers, this move serves as a massive opportunity to gain access to ChatGPT’s 800 million–plus users, with tools designed to build conversational experiences that merge chat and interactivity.

Josh Weisberg, Head of AI at Zillow, described the integration as a milestone for real estate tech.

“The Zillow app in ChatGPT shows the power of AI to make real estate feel more human,” he said.

“Together with OpenAI, we’re bringing a first-of-its-kind experience to millions — a conversational guide that makes finding a home faster, easier, and more intuitive.”

OpenAI also revealed that 11 additional partners will join the ecosystem later this year.

These include DoorDash, AllTrails, Khan Academy, Instacart, Target, Uber, Thumbtack, Tripadvisor, The Fork, Peloton, and OpenTable.

This will all take place as the AI giant begins to test monetization models and app submissions.

"OpenAI’s SDK reduces the complexity of connecting AI systems with real-world applications, which ultimately accelerates innovation for clients," Goran Skorput, CTO at tech firm Kanda Software, told DesignRush.

"Businesses no longer have to start from scratch; they can now build intelligent, context-aware solutions that plug directly into environments where users already engage."

How Apps in ChatGPT Work

When a user starts a message with an app name, ChatGPT detects it automatically and offers to connect.

Once authorized, the app gains access to only the data necessary to perform its function, like a playlist request or travel booking.

All while privacy prompts keep users informed about what’s being shared.

These features extend OpenAI’s recent commercial momentum.

Just weeks ago, the company introduced "Instant Checkout," a collaboration with Stripe that lets ChatGPT users complete purchases inside the chat itself.

Together, both launches suggest that ChatGPT is becoming less a chatbot and more a holistic operating system for AI-driven interaction.

But what does this mean for developers and startups?

The Apps SDK represents a shift toward openness.

Built on the Model Context Protocol, it lets apps connect directly to external data and services, with open-source components for interface design and chat logic.

Developers can define experiences that run inside ChatGPT or across other platforms that adopt the same standard.

This effectively turns ChatGPT into a shared environment for the next wave of AI tools.

However, this kind of integration could quietly wipe out the space where most startups thrive.

When users can design, search, and shop without ever leaving ChatGPT, smaller platforms lose the room to compete.

The future of startups may favor those who build within the ecosystem rather than try to exist outside it.

Also, privacy remains a central concern.

Each app must include clear data policies, collect minimal user data, and comply with OpenAI’s usage guidelines.

Later this year, OpenAI will add new privacy controls that allow users to specify which data categories apps can access.

A New Playground for Brands and Agencies

ChatGPT’s new app ecosystem can also be a new marketing canvas, just as it is a tech update. Here are some key lessons:

• Build branded utilities inside ChatGPT that solve real user needs instead of pushing promotions. Think of how Zillow or Canva uses conversation as a service touchpoint.
• Explore brand partnerships that let users experience your product through chat rather than seeing it in an ad.
• Treat AI-powered chat integrations as extensions of your customer funnel; a place where discovery, engagement, and even purchase can happen seamlessly.

Agencies that once focused on social or experiential activations can now design conversational ones.

The brands that succeed here will use these tools to make interactions feel helpful, not transactional.

Early movers like Spotify and Expedia are already showing how relevance and timing inside ChatGPT can drive natural engagement without disrupting the user experience.

Last year, OpenAI was valued at over $80 billion after a tender offer led by Thrive Capital, according to The Wall Street Journal.

Our Take: Can Chat Become The New App Store?

I’ve seen plenty of tech companies chase the "super app" dream.

Not long ago, Elon Musk proclaimed X would be an "everything app," but has since done little to change what the platform once was. 

And because achieving a super app is definitely a challenge, only a few can make it feel this seamless.

What OpenAI is attempting here isn’t about novelty but about convenience.

If done right, ChatGPT could become the connective tissue between creativity, commerce, and conversation.

The bigger question is whether users actually want this much capability inside a single chat window.

People come to ChatGPT for answers, not necessarily for everything else.

But if OpenAI manages to keep things intuitive and suggests the right tool at the right time, this could redefine what we expect from everyday AI.

The early integrations with Canva and Zillow make sense because they're practical, low-friction use cases that show immediate value.

What I’ll be watching next is how developers use the SDK.

Will they build tools that simplify life, or flood the chat with noise?

Either way, we’re witnessing the start of a new interface for the internet.

In related news, OpenAI launched its first-ever brand campaign for ChatGPT, opting to depict the tool as a part of everyday life. 

As AI becomes the new interface for the web, opportunity shifts to those who build utility that feels human.
