🚀 AI Stock Market Pulse - DevPost Submission

💡 Inspiration

The stock market is a complex ecosystem driven by data, sentiment, and human behavior. We were inspired by the potential of large language models (LLMs) to democratize investing by making sophisticated stock analysis accessible to everyone. Market news provide a real-time pulse of market sentiment, while financial statements offer deep insights into company performance. By combining these with AI, we aimed to create a tool that empowers both novice and experienced investors to make informed buy, hold, or sell decisions with confidence.
