why you should always generate a spec sheet before you start vibe coding_
A spec sheet is the difference between an app that looks like every other AI-generated project and one that actually has its own identity.
try the prompt builder ›The Problem_
Without a spec sheet, AI defaults to the same generic look every time. The same system font. The same blue buttons. The same gray borders. The same spacing that every other vibe-coded app has.
Your app ends up looking like a template because you're depending on whatever the AI feels like using that day. Every prompt gets different fonts, different colors, different spacing. Nothing is intentional.
Without a Spec Sheet_
It works. But it's system fonts, default colors, no personality. This is what every AI-generated app looks like when you don't give it direction.
With a Spec Sheet_
Same app, same data. Barlow Condensed for scores, DM Sans for body, navy + orange palette, consistent 8px radii. One prompt with a spec sheet made this.
What a Spec Sheet Gives You_
Your own palette. Not the AI's default blue. Your colors, chosen intentionally.
Your own typography. Pick fonts that match your vibe instead of whatever the AI defaults to.
Consistency across every component. Buttons, cards, badges, inputs all follow the same rules.
Hours saved. No more going back and forth tweaking individual elements. The AI gets it right the first time.
