Character builder with sliders demo

THE INSTRUCTIONS SHARED BY THE CREATOR

The creator’s prompt

A prompt is the text that tells the AI what you want it to make. Copy this one and paste it into your Claude Code project, adding what you’d like to change: the subject, wording, colors, or length.

The original text is preserved to respect the creator’s work. You can add instructions in your own language, even if the prompt is written in another language.

References not included

This prompt also uses images or files that aren’t included here. Bring your own references.

Build a live web editor for characters I generated on Magnific. Upload a PNG and tweak it in real time: head size, body shape from lean to sturdy, height, a colour lighting that tints the whole character, and a background for 4:5 PNG export. White UI, controls beside the character, zoom, save, delete and back to original

Copied the prompt? Here’s what to do next.

Open your project in Claude Code and paste the prompt alongside your own instructions.
Describe what you like about this video: its movement, colors, or pace. Sharing a URL alone doesn’t guarantee Claude Code can watch it.
Add your text and images, then ask for a first preview. Explain what you’d like to change from there.

An example instruction to add — adapt it to your project

Use the prompt above as a starting point for a 15-second video introducing my app. Replace the text with mine and use my colors. Before starting, tell me which files and tools you need, then put together a first preview.
