Build 'SafeFeed'—an AI-driven, privacy-preserving content moderation and parental control platform for minors on social media. The platform would: 1) Use federated learning to analyze content and user interactions in real-time without violating privacy; 2) Provide a 'Safety Profile' for different age groups to filter harmful content; 3) Offer a 'Parent Dashboard' to monitor activity and set usage limits; 4) Integrate with major social media platforms via API to enforce safety profiles.

Parents and educators struggle to protect minors from the harmful effects of social media algorithms, which can lead to addiction, mental health issues, and exposure to inappropriate content. Current solutions are either too manual (parental controls) or too invasive (content moderation). The financial cost of non-compliance includes legal penalties and potential reputational damage for social media platforms, which can significantly impact user growth and revenue.
