CodexWith Codex, creating custom apps to ease your workflow is as easy as writing a prompt. People are creating small apps to save time spent on research or figuring out the exact workflow. It's like having your own junior developer whose sole purpose is to automate the workflow and give you enough time to spend on important tasks.
In this guide, we will use Codex Desktop to build a small GPT Image 2 app that turns a marketing campaign and design brief into prompts, test images, and a simple review gallery. The goal is not to build some giant creative platform. It is to create a practical local workflow for content teams, marketers, founders, and Codex Desktop users who want to generate, test, and compare campaign visuals without scattered files, messy prompts, or random downloads.
By the end of this guide, you'll be able to:
Create a project folder
Build the app in Codex
Run the app and describe the campaign
Choose image dimension and generate prompts
Let's get started!
