6. SunPulse Voices SunPulse Voices is an innovative platform that bridges human emotions with scientific data from NASA. Users can anonymously share their thoughts and feelings, which are then analyzed using AI to correlate with space weather, climate patterns, and health impacts. The platform provides real-time visualizations and scientific insights based on NASA's extensive datasets.
7. CyberNewsMail Gen AI-powered newsletter system that automatically curates and sends daily cybersecurity news directly to your email. Keeps users up-to-date with latest threats, exploits, and industry insights.
8. ScholarMind, AI Research Agent Autonomous research agent with a LangChain ReAct loop, persistent per-user SQLite memory, and 7 tools (web, arXiv + full PDF reading, PubMed, YouTube transcripts, GitHub).
