Generate a comprehensive AI writing persona system based on the following data:
ONBOARDING DATA:
- Website Analysis: {onboarding_data.get('websiteAnalysis', {})}
- Competitor Research: {onboarding_data.get('competitorResearch', {})}
- Sitemap Analysis: {onboarding_data.get('sitemapAnalysis', {})}
- Business Data: {onboarding_data.get('businessData', {})}
TARGET PLATFORMS: {', '.join(platforms)}
REQUIREMENTS:
1. Generate a CORE PERSONA that captures the user's unique writing style, brand voice, and content characteristics
2. Generate PLATFORM-SPECIFIC ADAPTATIONS for each target platform
3. Ensure consistency across all personas while optimizing for each platform's unique characteristics
4. Include specific recommendations for content structure, tone, and engagement strategies
PLATFORM OPTIMIZATIONS:
- LinkedIn: Professional networking, thought leadership, industry insights
- Facebook: Community building, social engagement, visual storytelling
- Twitter: Micro-blogging, real-time updates, hashtag optimization
- Blog: Long-form content, SEO optimization, storytelling
- Instagram: Visual storytelling, aesthetic focus, engagement
- Medium: Publishing platform, audience building, thought leadership
- Substack: Newsletter content, subscription-based, personal connection
Generate personas that are:
- Highly personalized based on the user's actual content and business
- Platform-optimized for maximum engagement
- Consistent in brand voice across platforms
- Actionable with specific writing guidelines
- Scalable for content production
