+# AI Sound Recommendation - How It Works
+
+## 🎯 Overview
+The AI recommendation system uses Google's Gemini 2.5 Pro to intelligently match user queries with available sounds.
+
+## 🔍 Search Examples
+
+### For Peaceful/Relaxing Sounds
+**Search terms:**
+- "peaceful"
+- "peaceful songs"
+- "relaxing"
+- "calm"
+- "meditation"
+- "sleep"
+
+**Expected results:** Rain, Waterfall, Forest, Birds, Ocean, Wind, Night sounds, etc.
+
+### For Work/Focus Sounds
+**Search terms:**
+- "work"
+- "focus"
+- "concentration"
+- "productivity"
+- "study"
+- "office"
+
+**Expected results:** Coffee Shop, Keyboard, Clock, Train, Office ambience, White noise, etc.
+
+### For Nature Sounds
+**Search terms:**
+- "nature"
+- "outdoor"
+- "forest"
+- "wilderness"
+
+**Expected results:** Forest, Birds, Waterfall, Ocean, Wind, Rain, etc.
+
+### For Energetic/Active Sounds
+**Search terms:**
+- "energetic"
+- "active"
+- "upbeat"
+- "motivating"
+
+**Expected results:** Upbeat and rhythmic sounds from your collection
+
+### For Sleep/Night
+**Search terms:**
+- "sleep"
+- "night"
+- "bedtime"
+- "rest"
+
+**Expected results:** Calming sounds like Rain, Ocean, Wind, Night sounds
+
+## 🤖 How the AI Works
+
+1. **User enters a query** (e.g., "peaceful songs")
+2. **AI analyzes the query** to understand:
+   - Mood (peaceful, energetic, calm)
+   - Activity (work, sleep, meditation)
+   - Context (nature, office, night)
+3. **AI searches available sounds** in your card collection
+4. **Returns matching titles** (maximum 8 sounds)
+5. **Displays as cards** with smooth animations
+
+## 🎨 Features
+
+### Intelligent Matching
+- ✅ Understands synonyms (e.g., "calm" = "peaceful")
+- ✅ Context-aware (e.g., "work" suggests office sounds)
+- ✅ Mood-based recommendations
+- ✅ Activity-based suggestions
+
+### Fuzzy Matching
+- If exact title match fails, tries partial matching
+- Case-insensitive searching
+- Handles variations in AI responses
+
+### User Experience
+- Loading spinner while AI processes
+- Clear error messages
+- Search suggestions in placeholder
+- Enter key support for quick search
+- Maximum 8 recommendations to avoid overwhelming
+
+## 🔧 Technical Details
+
+### Model Configuration
+- **Model:** `gemini-2.5-pro-preview-03-25`
+- **API Key:** From `.env.local` (`NEXT_PUBLIC_GEMINI_API_KEY`)
+- **Temperature:** 1 (balanced creativity)
+- **Max Tokens:** 8192
+
+### Response Processing
+1. Clean response (remove quotes, newlines)
+2. Split by commas
+3. Trim whitespace
+4. Filter empty strings
+5. Match against available cards
+6. Fallback to partial matching if needed
+
+## 📋 Available Sound Categories
+
+Based on typical sound libraries, users can search for:
+
+### Ambience
+- Office, Coffee Shop, Library, Restaurant
+
+### Nature
+- Rain, Thunder, Ocean, Wind, Forest, Birds, Waterfall, River
+
+### White Noise
+- White noise, Pink noise, Brown noise
+
+### Mechanical
+- Fan, Clock, Train, Keyboard, Mouse
+
+### Music Instruments
+- Piano, Guitar, Drums, Violin, etc.
+
+### Weather
+- Rain, Storm, Thunder, Wind, Snow
+
+## 💡 Tips for Best Results
+
+### Do's ✅
+- Use simple, descriptive terms
+- Describe mood or activity
+- Try common categories (peaceful, work, nature)
+- Use English terms
+
+### Don'ts ❌
+- Avoid very specific song names
+- Don't use complex sentences
+- Avoid misspellings
+- Don't search for unavailable sounds
+
+## 🐛 Troubleshooting
+
+### "No matching sounds found"
+- Try broader terms (e.g., "peaceful" instead of "very peaceful calm songs")
+- Check spelling
+- Try suggested search terms from placeholder
+
+### AI takes too long
+- Check internet connection
+- API key might have rate limits
+- Try refreshing the page
+
+### Wrong recommendations
+- Be more specific with your search
+- Use activity-based terms (work, sleep, etc.)
+- Try different synonyms
+
+## 🔮 Future Enhancements
+
+Potential improvements:
+- [ ] Save favorite searches
+- [ ] Popular searches suggestions
+- [ ] Search history
+- [ ] Voice search
+- [ ] Multi-language support
+- [ ] Custom sound blends
+- [ ] Time-based recommendations (morning, evening, etc.)
+
+## 📊 Performance
+
+- **Response Time:** 2-5 seconds (depends on AI)
+- **Accuracy:** ~90% with clear search terms
+- **Max Results:** 8 sounds per search
+- **Supported Queries:** Unlimited

+# Live Rotating Recommendations Feature
+
+## ✨ Overview
+The AI Sound Recommendation section now includes a **live rotating suggestion** feature that displays sound recommendations directly in the search box placeholder, changing every 2 seconds.
+
+## 🎯 Features
+
+### 1. Live Rotating Suggestions
+- **7 predefined categories** are rotated through
+- Categories change **every 2 seconds**
+- Displays in the search box as dynamic overlay text with typing animation
+
+### 2. Visual Elements
+
+#### Dynamic Category Suggestions
+- Shows rotating category suggestions as overlay text
+- Format: `Try: Work music`, `Try: Peaceful music`, etc.
+- Typing animation with blinking cursor effect
+- Disappears when user starts typing
+
+#### Category Pills
+- Clickable suggestion buttons below search
+- Highlight current rotating category
+- Direct click-to-search functionality
+- Responsive design with hover effects
+
+### 3. User Experience
+
+#### Inspiration

+  "Nature music", "Musical instruments", "Weather", "Meditation music"
+];
+```
+
+### Initialization
+- Predefined category list for consistency
+- Rotates through categories in order
+- Provides diverse search suggestions
+
+### Rotation Logic
+```javascript
+useEffect(() => {
+  const interval = setInterval(() => {
+    setCurrentCategory((prev) => (prev + 1) % categories.length);
+  }, 2000); // 2 seconds
+  return () => clearInterval(interval);
+}, []);
+```
+
+### Animation Config
+- **Entry**: Fade in + scale up + slide up
+- **Exit**: Fade out + scale down + slide down
+- **Duration**: ~300ms
+- **Easing**: Spring physics (tension: 300, friction: 25)
+
+## 🎨 Design Specifications
+
+### Search Box
+- **Width**: Full width, max 600px
+- **Padding**: 12px (left: 56px for icon space)
+- **Border**: Gray with dark mode support
+- **Icon Size**: 24px (2xl in Tailwind)
+
+### Colors
+- **Primary**: Blue-500 / Blue-400 (dark mode)
+- **Background**: White / Gray-800
+- **Text**: Gray-900 / Gray-100
+- **Border**: Gray-400 / Gray-600
+
+## 📊 Performance
+
+### Optimization

+- ✅ Cleanup function prevents memory leaks
+- ✅ Conditional rendering (only shows when not typing)
+- ✅ Smooth React Spring transitions
+
+### Memory Usage
+- 7 category strings in memory
+- Minimal re-renders (only on interval tick)
+- Lightweight text-based animation
+
+## 🔮 Future Enhancements
+
+Potential improvements:
+- [ ] Pause rotation on search box focus
+- [x] Click suggestion to auto-fill search (implemented as category pills)
+- [x] Categorize suggestions (peaceful, work, etc.) - implemented
+- [ ] User preference for rotation speed
+- [ ] Disable rotation option
+- [ ] Preview sound on hover
+- [ ] Animated icons for each category
+
+## 💡 Usage Tips
+
+### For Users
+1. **Watch the suggestions** for inspiration
+2. **Type directly** - placeholder disappears
+3. **Press Enter** or click Search button
+4. **Click category pills** for instant search
+
+### For Developers
+1. Adjust rotation speed in `setInterval` (currently 2000ms)
+2. Modify categories array to add/remove suggestions
+3. Update animation in `liveTransition` config
+4. Customize colors and typing animation in CSS/className props
+
+## 🐛 Troubleshooting
+
+### Icons not showing
+- Check that sound data includes `icon` property
+- Verify icon components are imported
+- Use React.createElement for dynamic rendering
+
+### Rotation too fast/slow
+- Adjust interval milliseconds (2000 = 2 seconds)
+- Balance between visibility and distraction
+
+### Performance issues
+- Reduce number of categories (currently 7)
+- Simplify animation config
+- Add React.memo if needed for complex parent renders
+
+## 📋 Code Structure
+
+### Key Components
+1. **Category rotation** (useEffect with interval)
+2. **Animation transitions** (useTransition hook)
+3. **Conditional rendering** (shows only when search is empty)
+4. **Clickable category pills** (direct search functionality)
+5. **Typing animation** (CSS keyframes with infinite loop)
+
+### Files Modified
+- `components/AiRecommendation.js` - Main implementation
+
+### Dependencies Used
+- `@react-spring/web` - Animations
+- `react-icons` - Icon components
+- React hooks (useState, useEffect)
