How to use UIFit with Claude
Pick a design system
Browse 64 real-world design systems on UIFit's live dashboard. See how Linear's minimal style, Stripe's precision, or Apple's premium feel looks on a complete interface — before you export anything.
Export the AI System Prompt
UIFit generates a comprehensive design specification — colors, typography, spacing, components, interaction patterns, and UX principles — formatted specifically for AI assistants to understand and follow.
Paste into Claude's system prompt
Add it as a system prompt in Claude.ai, or pass it as the system parameter in the Claude API. From that point on, every piece of UI code Claude writes respects your chosen design system.
What the AI System Prompt includes
UIFit's AI System Prompt is a structured, 300+ line design specification covering:
- → Complete color system with semantic tokens (primary, surface, border, text, error, success)
- → Typography: font families, size scale, weight usage, line height rules
- → Spacing and layout grid principles
- → Component behavior rules (how buttons, cards, inputs, modals should look and feel)
- → Motion and animation guidelines
- → Light and dark mode token values
- → Brand personality and UX principles (what makes this design system distinctive)
Works with Claude Code too
If you use Claude Code in the terminal or IDE, export UIFit's .cursorrules or the AI System Prompt and include it in your project's CLAUDE.md file. Claude Code will apply the design system to every file it touches in that project.
UIFit also exports for ChatGPT, Gemini, Windsurf, GitHub Copilot, and any AI tool that accepts system prompts or instruction files.

FAQ
How long is the AI System Prompt?
Typically 300–500 lines depending on the complexity of the design system. It's structured so Claude can reference specific sections — colors, typography, components — without getting confused by the length.
Does this work with the Claude API?
Yes. Pass UIFit's export as the system parameter in your Claude API calls. All responses will follow the design system for the duration of that conversation or session.
Can I combine multiple design systems?
Yes — UIFit's Hybrid mode lets you blend two design systems before exporting. Take Linear's typography with Stripe's color system, or Apple's spacing with Figma's motion. The exported prompt includes the blended result.
