💡 Best Practices for Using CANVAS

Before You Start

  • Have a completed SPARK prompt ready as your foundation
  • Identify any specific design preferences or brand guidelines
  • Consider your target audience's design expectations
  • Think about unique visual elements that differentiate your app
  • Prepare any reference websites or design inspiration

Crafting Your CANVAS Prompt

  1. Include SPARK Output: Paste your complete SPARK prompt as context
  2. Specify Design Preferences: Mention colors, fonts, or style preferences
  3. Reference Inspiration: Include URLs or descriptions of design inspiration
  4. Clarify Platform: Specify if mobile-first, web-first, or specific platform needs
  5. Mention Constraints: Any technical or accessibility requirements

⚠️ Potential Pitfalls & How to Avoid Them

Common Issues

  1. Generic Design Output: CANVAS might produce template-like designs without unique character
  2. Over-Specification: Too much detail can overwhelm AI coding platforms
  3. Brand Misalignment: Generated designs might not match existing brand guidelines
  4. Technical Feasibility: Suggested animations or interactions might be complex to implement

Prevention Strategies

  • Provide Brand Context: Include existing brand colors, fonts, and style guidelines
  • Specify Uniqueness: Ask for distinctive elements that set your app apart
  • Validate Feasibility: Review technical recommendations with your development constraints
  • Customize Output: Edit the generated guidelines to match your specific needs

💰 Credit Optimization Strategies

Maximize Efficiency

  • Complete SPARK First: Have your functional requirements fully defined
  • Single Comprehensive Prompt: Include all design preferences in one request
  • Reference Materials Ready: Have inspiration links and brand assets prepared
  • Batch Similar Projects: Process related apps together for consistency

When to Use CANVAS vs. Manual Design

Project Type Recommendation Reason
Complex multi-page app Use CANVAS Comprehensive guidelines worth the investment
Simple landing page Consider manual May be overkill for basic layouts
First-time design project Use CANVAS Educational value and professional structure
Existing brand guidelines Hybrid approach Use CANVAS then customize for brand
