ChatGPT app development

Custom ChatGPT app development

We turn a specific business workflow into a reliable app that works directly inside ChatGPT.

What it means

A custom ChatGPT app combines conversational guidance with tools that can retrieve data, perform calculations and complete controlled actions. Unlike a prompt-only assistant, it has an explicit product interface, permissions and business logic.

What we deliver

A validated workflow and interaction model
An MCP server exposing focused business capabilities
An Apps SDK interface for structured input and results
Testing, deployment, observability and iteration

How we work

Discover

We identify the user, recurring task, required evidence and measurable outcome.

Design

We define conversation, tool boundaries, interface states and human checkpoints.

Build

We implement the MCP server, widget, integrations and production safeguards.

Launch

We validate real use, monitor reliability and improve the app from observed behaviour.

Frequently asked questions

What can a ChatGPT app do?+

It can combine language with approved tools for data retrieval, calculations, structured decisions and actions in external systems.

Can it connect to company systems?+

Yes. We design narrowly scoped MCP tools around existing APIs, databases and access rules.

Is this different from a Custom GPT?+

Yes. A production app uses the Apps SDK and MCP to provide dedicated UI, tool contracts and deeper control over integrations.
