# Research Input Placeholder Personalization Implementation
## Date: 2025-12-31
---
## ✅ **Validation: Research Persona Storage**
**Status**: ✅ **Confirmed - Research persona is successfully stored in database**
**Validation Results**:
- PersonaData record exists with ID: 1
- Research persona field is populated (not None)
- Generated at: 2025-12-31 11:47:49
- Contains all expected fields:
- `default_industry`: "Content Marketing"
- `default_target_audience`: (populated)
- `research_angles`: Array of research angles
- `recommended_presets`: Array of personalized presets
- `suggested_keywords`: Array of suggested keywords
---
## 🎯 **Implementation: Personalized Placeholders**
### **What Was Changed:**
#### **1. Enhanced Placeholder Function** (`placeholders.ts`)
**Added**:
-`PersonaPlaceholderData` interface to type persona data
- ✅ Enhanced `getIndustryPlaceholders()` to accept optional persona data
- ✅ Logic to generate placeholders from:
- **Research Angles**: First 3 angles formatted as research queries
- **Recommended Presets**: First 2 presets with their keywords and descriptions
- ✅ Fallback to industry defaults if persona data is unavailable
**How It Works**:
```typescript
// If research persona exists:
1. Extract first 3 research_angles Format as placeholders
2. Extract first 2 recommended_presets Use keywords + descriptions
3. Combine with 2 industry defaults as backup
4. Return personalized placeholders array
// If no persona:
1. Fall back to industry-specific defaults
```
#### **2. Updated ResearchInput Component** (`ResearchInput.tsx`)
**Added**:
-`researchPersona` state to store persona data
- ✅ Logic to extract persona data from `config.research_persona`
- ✅ Pass persona data to `getIndustryPlaceholders()` function
**Flow**:
```
Component Mount
Load Research Config
Check if research_persona exists
Extract research_angles and recommended_presets
Store in researchPersona state
Pass to getIndustryPlaceholders(industry, personaData)
Display personalized placeholders
```

## 📊 **Placeholder Generation Logic**
### **Priority Order:**
1. **Research Angles** (if available)
- Format: `"Research: {angle}"` or use angle as-is if it contains `{topic}` placeholder
- Example: `"Research: Compare {topic} tools"``"Research: Compare Content Marketing tools"`
- Adds helpful description: "This will help you: Discover relevant insights..."
2. **Recommended Presets** (if available)
- Uses preset keywords directly
- Includes preset description if available
- Example: Uses actual preset keywords from persona
3. **Industry Defaults** (fallback)
- Uses original industry-specific placeholders
- Only used if no persona data or as backup
### **Example Output:**
**With Research Persona**:
```
Research: Compare Content Marketing tools
💡 This will help you:
• Discover relevant insights and data
• Find authoritative sources and experts
• Get comprehensive analysis tailored to your needs
---
Research latest content marketing automation platforms for B2B SaaS companies
💡 Analyze competitive landscape and identify top content marketing tools and strategies
```
**Without Research Persona** (fallback):
```
Research: Latest AI advancements in your industry
💡 What you'll get:
• Recent breakthroughs and innovations
• Key companies and technologies
• Expert insights and market trends
```

2. **User Feedback**: Allow users to rate placeholder helpfulness
3. **Dynamic Updates**: Update placeholders when persona is refreshed
4. **A/B Testing**: Compare personalized vs. generic placeholder effectiveness
---
## 🎉 **Summary**
✅ Research persona storage validated

✅ Graceful fallback for users without persona
The research input placeholders are now fully personalized based on the user's research persona, providing a more relevant and helpful experience for content creators.
