// Common questions
What is vibe coding?
Vibe coding is building software by describing what you want in plain English and letting an AI coding tool write the code — you steer, it types. The term was coined by Andrej Karpathy in early 2025. Every idea on this site ships with a build prompt designed for exactly this way of working.
How do I come up with an app idea worth building?
Start from a pain a specific group of people already pays to solve, not from a technology. The test is three parts: a narrow audience you can name, a task they currently do badly by hand or in spreadsheets, and evidence they spend money on it. Every idea in this directory is built on that test.
Are these ideas free to use?
Yes. Build anything here, ship it, and keep every penny. There is no license, no attribution requirement, and no catch. If you do build one, email hello@appideas.ai and we will link to your project.
