Find your first digital product. Before you start building.

Most people who want to build with AI are not stuck because they need more tools. They are stuck because they have not decided what to build. This short guide helps you decide.

01What's inside

One guide. One question.

The whole guide is built around answering one question: what should I build first?

  • See product ideas in your own experience, not just in trend lists
  • Spot problems worth solving without months of research
  • Match an idea to a realistic first format (PDF, tool, GPT, template, more)
  • Cut your idea down to a version you could actually finish
  • Pick one idea and describe it in one sentence
  • Use the free Product Discovery GPT to think out loud
02Honest fit check

Is it for you?

This is for you if…

  • You want to build something with AI but do not yet know what
  • You have ideas but cannot decide which one to chase
  • You keep researching instead of starting
  • You want a clear method, not another firehose of advice

This is not for you if…

  • You are looking for a get-rich-with-AI pitch
  • You want to be told exactly which business to start
  • You want endless theory before doing any work
  • You already know what you are building (skip ahead and ship)
Who wrote this

No hype. No fake income screenshots. Just the work.

I'm David Jupijn. I build digital products with AI, from small one-weekend tools to larger systems, and write about what actually moves people from idea to shipped.

One more thing

The free guide answers what to build.

When you know what to build, the next step is to actually build it. The full system that walks you from idea to a shipped first product lives on the homepage.
