Note
Definition

A project brief is a short, structured summary of what you are building. It usually includes one paragraph describing the app, who it is for, and what it does, followed by a list of Must Have features. This is what you will give to Claude Code when it is time to start building, so the clearer it is, the better your starting point will be.

You have your feature list, and you know which ones are Must Haves. That is all you need to create a project brief.

Instead of writing it from scratch, you can use Claude chat to generate it. This is the regular chat interface, not Claude Code. You describe your idea, mention that it is an MVP, and ask Claude to turn it into a project brief. It will handle the structure and give you something ready to use.

For the AI Idea Validator, the prompt can be simple: Give me a project brief for an AI idea validator. This is an MVP, so focus on the essential features only.

Claude will return a formatted brief with a problem statement, target user, and a prioritized feature list based on your idea.

Once you have it, save it somewhere easy to find. This brief will act as your blueprint for everything that comes next.

Open Claude Chat and use it to turn your feature list into a project brief

Open Claude.ai and use it to turn your feature list into a project brief. Start by typing a one or two sentence description of your app idea, then let the conversation develop.

Ask Claude to help you refine it, tighten the scope, and shape it into a clear one-paragraph brief with your Must Have features listed. When you're happy with it, copy it somewhere easy to find. You will be using it in the next section.
