Give NeedGen a rough product idea and it returns a spec your engineers can plan against. Any LLM can draft requirements. The trick was making it reliable, and cheap enough to run on every idea — about $0.007 a go.
The problem
Requirements are where ideas stall. They're either too vague to build or written so late the team has already guessed. I wanted something that takes an idea at its messiest and hands back a clear spec, fast.
How it works
Four agents each handle one step — reading the idea, breaking it into features, writing the spec, and reviewing it. They pass structured context to each other instead of re-deriving it, so every call stays small and cheap. Teams can edit what comes out and feed it back in.
What I learned
Keeping it at ~$0.007 a run changed how people used it. When generating a spec is basically free, you do it constantly instead of saving it for the ideas you're already sure about.
