What It Is
You find a boring task that a specific group repeats and complains about, such as research for publishers, scripts for real estate agents or a system for coaches, and build a lightweight AI tool around it using OpenAI's GPT builder, Poe or another no-code platform. People pay monthly for access. The creator's own example is the AI book-writing software he built after years of seeing publishers pay ghostwriters and designers.
The Pitch
He says this has the highest income potential of his five digital products because it's subscription-based, has no platform taking a big cut, and keeps users if it solves a weekly problem.
Who It’s Best For
People who already know a niche well enough to spot a real, repeated pain point; not a first project.
The Truth (as we see it)
He ranks it last for beginners himself: you need deep knowledge of a market to know what to build, and real software is the most time-consuming and expensive option on his list. Simple custom GPTs are easy to copy and hard to charge for unless they're tied to real expertise or data. The example he gives is his own paid product.
