v0 Prompt Generator
Generate production-ready React components from v0 on the first prompt.
v0 by Vercel generates React components using shadcn/ui and Tailwind CSS by default. Prompts that specify component state, layout hierarchy, interaction behaviour, and visual constraints produce components that need minimal post-generation editing.

v0 by Vercel generates React and Next.js UI components from text descriptions — and the quality gap between a weak prompt and a strong one is enormous. v0 produces its best work when you describe exact layout, component state, interactivity, and visual design rather than just the general idea. PromptIt structures your rough UI description into a v0-ready prompt with the specificity v0 needs to generate copy-paste-ready components.
What makes a great v0 prompt?
Describe layout structure with precise hierarchy: 'A card with a header (title left, badge right), a body with two columns (details left, chart right), and a footer with two action buttons'
Define all component states explicitly: default, hover, loading, empty, error — v0 generates multi-state components when asked, saving you significant implementation work
Specify the exact shadcn/ui components you want used when you have preferences: 'Use Dialog, not a custom modal', 'Use a DataTable, not a plain table'
Describe interactions: 'Clicking the row opens a side panel with full details', 'The form validates on submit and shows inline error messages' — v0 implements these when described
Before & after: how PromptIt improves your v0 prompts
Specified the two-column layout, all navigation sections, every field and interaction in each section, and the confirmation pattern — giving v0 a complete UI spec to implement.
