The AI euphoria is fading, and a question comes up: what app is actually worth building?
At first I was excited making mini apps, services, and all sorts of scripts I’d wanted to build for years but never had time for. Great, I did it. Automated some processes, improved a few things. But what’s next?
Now the biggest weakness is project viability. I can build a lot on my own, but will it be useful? Will it be profitable?
You need to validate whether anyone will pay for it, or whether it saves real budget inside a company. That’s harder than just vibe-coding another service.
The good news: this problem has always existed. Figuring out whether an idea is worth pursuing is not new. It predates AI by decades.
What changed is the cost of testing. You need far less time and money to build a prototype and put it in front of real users. The validation loop is faster — not the question itself.
Before building anything, I ask two questions:
If neither answer is clearly yes, it stays in the idea folder.
The tools are incredible now. The hard part is staying honest about what’s actually worth shipping.
