  • Completely free, no sign-up required
Secret advantage: You get access to premium models like GPT-4 and Claude Opus for FREE that normally cost $20/month!

1 Getting Started with LMArena

  1. Open your browser and go to lmarena.ai
  2. Click "Arena (battle)" mode
  3. You'll see two chat boxes side by side
  4. Type your prompt once - it goes to BOTH AIs
  5. Compare responses and pick the winner!

2 Pro Tips for LMArena

  • Direct Chat Mode: If you find a model you love, switch to "Direct Chat" to use just that one
  • Copy Best Parts: Take the best code from each model and combine them
  • Iterate: Ask follow-up questions to refine the code
  • No Limits: Generate as much as you want - it's FREE!

Part 3: Build an Interactive Human Body Learning Tool

2 hours

🎯 Today's Challenge: Interactive Human Body Systems Viewer

What we're building: An educational tool that shows different body systems with interactive toggles!

❤️
Cardiovascular

Heart & blood flow

🧠
Nervous System

Brain & nerves

💨
Respiratory

Lungs & oxygen

Features Your Project Will Have:

  • SVG human body outline
  • Three toggle buttons for each system
  • Animated flow effects (blood, nerve signals, oxygen)
  • Color-coded systems (red, blue, green)
  • Info panels that appear on hover
  • Mobile responsive design
  • Educational descriptions

1 Phase 1: Generate Base Code with LMArena

Copy this master prompt and paste it into LMArena (both models will compete!):

Create an interactive human body systems viewer as a single HTML file. Requirements: 1. SVG-based human body outline (front view, simplified) 2. Three toggle buttons: Cardiovascular, Nervous, Respiratory 3. Each system shown in different colors: - Cardiovascular: Red paths showing heart and major blood vessels - Nervous: Blue paths showing brain, spine, and major nerves - Respiratory: Green showing lungs and airways 4. Interactive features: - Click toggles to show/hide each system - Animated flow effects: - Cardiovascular: pulsing red dots flowing through vessels - Nervous: blue sparks traveling along nerve paths - Respiratory: green particles showing oxygen flow 5. UI Design: - Modern dark background (#1a1a2e) - Glowing effect on active systems - Toggle buttons with on/off states - System labels and descriptions - Smooth transitions when toggling 6. Educational info boxes: - Hover over organs to see descriptions - Facts about each system in side panel Use CSS animations, SVG paths, and JavaScript for interactivity. Make it visually impressive with a medical/scientific feel.

After generating: Compare both outputs and copy the better one!

2 Phase 2: Test and Refine with NanoBanana

Take your code to NanoBanana for quick iterations:

Here's my human body systems viewer code: [PASTE YOUR CODE] Please improve it by: 1. Making the animations smoother 2. Adding heartbeat animation to the heart 3. Creating a legend/key for the colors 4. Adding a "Show All" and "Hide All" button 5. Improving mobile responsiveness

3 Phase 3: Polish with Claude.ai

For the final polish, use Claude.ai (your free account) to perfect it:

I have this human body systems viewer: [PASTE CODE] Please enhance it with: 1. More anatomically accurate organ positions 2. Gradient backgrounds for a professional look 3. Sound effects option (heartbeat, breathing) 4. Educational quiz mode with 5 questions 5. Print-friendly version for students 6. Accessibility features (keyboard navigation, ARIA labels) 7. Loading animation when page starts 8. Statistics dashboard showing system facts Keep everything in a single HTML file.

🎨 Refinement Techniques

If the body outline is too simple:

Make the human body outline more detailed with: - Visible head, neck, torso, arms, legs - Basic organ shapes (heart, lungs, brain, stomach) - Proper proportions - Smooth curves, not blocky

If animations aren't working:

Fix the animation system: - Ensure all CSS @keyframes are defined - Add animation timing and easing - Create continuous loops for flow effects - Debug any JavaScript errors in toggle functions

For better visual effects:

Enhance visual appeal with: - Glow effects using CSS filters - Particle systems for oxygen - Pulse effects synchronized with heartbeat - Transparent overlays for depth - Color gradients along system paths
Pro Workflow: Use LMArena for initial generation → NanoBanana for quick fixes → Claude.ai for final polish. Each tool's strength complements the others!
