In plain English
Instead of writing code line by line, you tell an AI tool what you want, try the result and ask for changes until it works. People with little or no coding experience can build working apps this way, but nobody may fully understand what's under the hood.
Example
A marketing manager describes a simple tool for tracking event sign-ups, and an AI coding assistant builds it in an afternoon. She tests it by clicking around rather than reading the code.
In short
Describe it. Don't code it. You say what you want and AI writes the code.
Why it matters
Vibe coding lets more people build their own tools and lets teams test ideas fast. The risk is code nobody has reviewed, which can hide bugs and security holes. Many teams use it for prototypes and an MVP, then review the code before anything goes live.
Common confusion
Vibe coding vs. AI-assisted coding. Plenty of developers use AI to write code but still read, test and own every line. Vibe coding means trusting the output and going with the flow. That's fine for a weekend project and risky for a bank.
