Summary  
This chapter covers how to transform a vague product idea into a concrete list of core features by selecting a minimal set of functionalities (around five) to define and guide the first working version of an application.

General domain of usage  
Software product planning and minimum viable product (MVP) development

Most people start with a vague idea. Something like "I want to build an app that helps people validate their business ideas." That's a starting point, but it's not a plan. You can't build from a feeling. You need to turn it into something concrete enough to act on. The good news is this doesn't need to be complicated.

### What is a feature?

A feature is just a thing your app can do. Not what it might do one day. What it does in its first working version.

All you need is five features. A short list that describes what your app actually does when someone opens it for the first time.

A simple field where the user can clearly describe their idea in their own words.

Text input for the idea

A button that sends the idea to the AI for evaluation.

Submit button for analysis

The AI highlights what works well and where the idea has potential.

AI breakdown of strengths

The AI points out gaps, risks, or unclear parts that need improvement.

AI identification of weaknesses

A simple, easy-to-read page that displays the feedback in a structured way.

Clean results page

No user accounts. No payment plans. No sharing features. Just the five things that make the app work.

Getting your thinking out of your head and onto the page gives you something to work with. A rough list you can actually start from is worth more than a perfect plan you are still thinking about. Done beats perfect every time.

What best describes a feature when turning your idea into a simple plan?

Build and launch a real app in just one weekend using modern AI tools and a simple, practical workflow, using Claude Code to plan, generate, and refine your code, managing your project with GitHub, and deploying your finished app online with Vercel. You’ll start with an idea and quickly turn it into a clear project plan, then move step by step into building a working application, focusing on core features, simple architecture, and fast iteration instead of unnecessary complexity, while learning how to work effectively with AI by writing better prompts, fixing errors, and improving features, ending with a live app, a clean GitHub project, and a repeatable system for turning future ideas into real products faster.

Understand the basics of AI-assisted development, set up your environment, and get familiar with Claude Code before starting your first app.

Turn your idea into a clear, simple plan and define the smallest version of your app that delivers real value.

Go from zero to a running app by generating code with AI, setting up the project, and understanding what was created.

Improve your app by adding features, refining the design, and learning how to fix issues effectively.

Publish your project, make it accessible online, and ensure everything works using GitHub and Vercel.
