ChatGPT Application Development Services

Develop custom apps that work directly inside ChatGPT using the Apps SDK. Leveraging its capabilities, we help businesses build context-aware ChatGPT apps with tools for DevTools integration, Search/RAG systems, content generation systems, and custom AI tools.

 

About ChatGPT App Development

Application development inside ChatGPT allows introducing your product to users when they need it, instead of convincing anyone and everyone to download it. Your ChatGPT app operates directly inside the chat, with no need for user onboarding and separate interfaces. This shortens time to value and improves user satisfaction.

Besides , the number of ChatGPT apps is still small. With much lower competition, you have a chance to draw attention and become a default in your category. You can quickly build and launch a conversational app version of a popular product. An OpenAI/ChatGPT app unlocks access to 800+ million users.

On the technical side, development is streamlined with built-in infrastructure. Interactive UI is built with React and rendered inside ChatGPT, while application logic typically runs in Python within a managed backend. We are one of the few teams worldwide with proven experience in building applications for ChatGPT.

FAQ

These are the answers to the most frequently asked questions about ChatGPT application development services. If your question isn’t answered in this section, please contact us to discuss it further.

How long does it take to build a ChatGPT app?

Most ChatGPT apps can be built and launched much faster than traditional ones. A functional version often takes just a few weeks, depending on complexity and integrations. Since the platform already provides the interface and infrastructure, teams can focus on core functionality instead of building everything from scratch.

How do users find an app inside ChatGPT?

Apps can be found through direct invocation or suggested by ChatGPT when there is a relevant intent. This means users encounter your product while already trying to solve a problem. Such a discovery method leads to higher-quality engagement compared to traditional discovery methods.

Is ChatGPT app development different from building a regular web or mobile app?

ChatGPT apps run inside an existing conversational platform, so there’s no need to design full screens, navigation, or onboarding flows. The interface is conversational, with interactive components where needed, and much of the backend is managed. This significantly reduces development effort and complexity.

Can we use a frontend other than React?

At the moment, ChatGPT apps support React for the in-chat interface. However, your backend API can still be shared with another frontend built separately. We have experience designing architectures where a ChatGPT app runs alongside a parallel frontend using the same API.
