To create an app with ChatGPT, use it to define the app idea, features, and user flow, then convert that plan into prompts for an AI-powered app builder like Hostinger AI Builder to generate, test, and publish a working app. While ChatGPT can generate raw code for manual development, that method requires managing project files, choosing the tech stack, and deploying the app yourself. The faster approach is using ChatGPT for planning and Hostinger AI Builder for generation and hosting. The six steps include: using ChatGPT to define the app’s goal, scope, and user flow; condensing the plan into a structured prompt with layout, features, validation rules, and design requirements; pasting the prompt into Hostinger AI Builder to generate a functional first version; configuring backend features like a database, account-based authentication for the admin dashboard, and Stripe for payments; testing forms, permissions, and edge cases in the builder’s preview, then describing issues for the AI to fix; and publishing the app on Hostinger with web hosting, an SSL certificate, and a custom domain included. The planning process involves defining the problem and target user, identifying the most important action, limiting the first version to three essential features, and mapping the user flow. The tutorial uses a hair salon appointment-booking app as an example, where a client selects a service, date, and time slot, and the app collects name, email, preferred service, appointment date, and time slot.
