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. At SECL Group, a functional version often takes just a few weeks to build, 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.
How does the development process for a ChatGPT app usually start?
Most projects like this generally begin with a discovery phase. SECL Group’s team reviews the workflows you want to support with a ChatGPT app and the systems it needs to connect to. After this, we build a prototype so stakeholders can see how the application behaves inside ChatGPT.
What happens after a ChatGPT app is launched?
Most ChatGPT apps continue to evolve after deployment. Software development teams may improve prompts or expand the supported integrations. Vendors like SECL Group that specialize in software development can maintain the application and update it as new use cases appear.
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.
How can a ChatGPT app integrate with our existing tools?
ChatGPT apps can connect to internal systems through APIs or service layers. They can retreive data, or interact with platforms your team already uses. We at SECL Group pay special attention to integrations with other systems while developing ChatGPT apps.
Can ChatGPT apps work with company documentation or knowledge bases?
Yes, these apps can be built around search or retrieval systems that allow an application to assess an internal knowledge base. We at SECL Group emphasize access control when building ChatGPT apps that access enterprise data.
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. SECL Group team has experience designing architectures where a ChatGPT app runs alongside a parallel frontend using the same API.
What kinds of problems can ChatGPT apps solve for a business?
These apps can be used to simplify access to data and automate routine processes. SECL Group has built ChatGPT apps that help retrieve information, generate reports, and help employees navigate complex systems. Such apps interact in a conversational way.
Do ChatGPT apps replace existing software tools?
Usually not, they work as an addition. ChatGPT apps are generally an additional layer that simplifies access to existing software. Users can interact with them via a conversational interface instead of navigating multiple systems to retrieve data.
