Is ChatGPT Enough to Build an App? Not Without This Critical Step

13 July 2025
ChatGPT can write code. But can it build a real app? That’s the question many indie founders, developers, and AI enthusiasts are asking. The promise is seductive: describe your idea in plain English, and let the AI do the rest. But once you go beyond a simple UI component or a function, the magic begins to break.

The Problem with AI-Only Development

Let’s say you ask ChatGPT:

“Create an app that lets users rent bikes from nearby stations.”

What you might get:

  • A login page
  • A list of fake stations
  • Some nice UI boilerplate

What you won’t get:

  • A consistent flow between screens
  • Defined user roles (admin vs. rider)
  • Data models with relationships
  • Error states, edge cases, fallback logic
  • How payments, location access, or notifications work

The AI is smart, but it’s not a product designer. It fills in gaps—but if your idea has lots of gaps, the result is unstable, unscalable, and often... unusable.

Why You Still Need a Product Spec

In any successful build, the spec is where clarity begins. It’s where you answer:

  • What does the app actually do?
  • Who are the users, and what are their goals?
  • What happens when something goes wrong?
  • How does everything connect?

Even when working with ChatGPT, GPT-4o, or other LLMs, the lack of a solid blueprint creates friction, confusion, and bugs. Garbage in = garbage out. Especially when AI is listening.

Enter Specifys.AI: From Idea to Clarity

Specifys.ai was born for this exact moment in tech. It doesn't replace ChatGPT—it prepares it. You describe your app idea, answer a few smart prompts, and within a minute, you get:

  • A full feature list
  • Screen breakdowns and user flows
  • Suggested architecture
  • Role-based logic and edge case handling
  • Export-ready documentation for devs or AI agents

Think of it as your pre-coding co-pilot—the strategist before the builder.

Real-World Example

🚫 Without Specifys:

“Build a journaling app.”

🛠️ With Specifys:

“Build a journaling app with three user types (free, premium, admin). Features include daily prompts, streak tracking, offline mode, and encrypted backups. Users should be able to set reminder times and export entries. See full spec for flow.”

Now ask ChatGPT to write code based on that? It flies.

The New Stack: Specifys + GPT

Your AI coding workflow shouldn’t start with code. It should start with intention. With Specifys.ai, you design your app in language that makes sense—then plug that clarity into ChatGPT or your favorite AI dev tool.

You’ll ship faster. You’ll debug less. You’ll look 10x more prepared.
