Vibe Coding with a planning assistant to build with clarity
Most AI app builders jump straight into building. That feels fast until your app gets messy, inconsistent, and nothing like what you imagined. Today, we’re introducing Spec Coding in Capacity. Instead of building immediately, Capacity now lets you define your app first with the help of an AI co-founder that asks the right questions before any code is generated. More structure upfront. Far less refactoring later. Much better results.
Hey Product Hunt 👋
Samuel here, maker of Capacity.
We love vibe coding it’s fun and incredibly fast.
But after building a lot of real apps with AI, we kept running into the same problem:
AI builds confidently, even when the idea isn’t clear.
Humans ask questions.
AI doesn’t, it guesses.
So we built Spec Coding.
Before any code is written, an AI co-founder helps you define:
-what you’re building
-who it’s for
-what matters
-and what doesn’t
It slows down the first minute…
and saves hours later.
Would love your feedback especially if you’ve ever rebuilt the same AI app three times 😄
Happy to answer any questions!
