How do I generate a v0 prompt from a website component?

Use Slicer to extract the component from any website. Export as AI Prompt and paste directly into v0.dev. Slicer's prompt contains all design specs — v0 generates from a real reference instead of its defaults.

Can I use Slicer with v0 by Vercel?

Yes. Slicer's AI Prompt export is designed for tools like v0. Paste the export and v0 generates based on real extracted design specs.

How do I make v0 stop generating generic shadcn components?

Give v0 a real reference instead of a vague description. Extract the component you want from a real website with Slicer and paste the AI prompt into v0. The output inherits the design quality of the original.

Do I need to write a prompt for v0?

No. Slicer's AI Prompt already contains everything v0 needs — exact colors, spacing, hover states, animation timing, responsive rules. Just paste it in.

Slicer + v0

Generate v0 prompts from real website components

v0 generates from training data — which skews toward shadcn defaults. Give it a real component from a real website instead of a description from memory.

The difference between describing and showing

When you prompt v0 with a description, it fills in what you didn’t specify with defaults. A Slicer export fills in everything.

v0 from description

rounded-lg→ default shadcn radius

bg-white→ generic white card

text-gray-900→ default text color

hover:shadow-md→ basic hover effect

Same output as every v0 component

v0 from Slicer export

rounded-xl→ from real component

ring-1 ring-gray-100→ subtle ring, not border

hover:-translate-y-0.5→ lift on hover

transition-all duration-200→ exact timing

From a component that already ships on production

v0 defaults to the statistical average of its training data. Slicer gives it a specific, real component to adapt — and v0 produces specific, real output.
