Persona	Focus

🚀 Founder	Startups, funding, tech, innovation

💼 Professional	Business, policy, corporate, governance

• AI Summary — 4-5 bullet points from any article in seconds
• Why It Matters — persona-aware real-world impact analysis
• Chat with article — ask any question, get AI answers based on the article
