About
Prospero.ai is an AI-driven investing platform designed to simplify stock research and give retail investors an institutional-grade edge. The app ingests vast amounts of market data—including institutional trading activity, price trends, and sentiment indicators—and distills them into clear, signal-driven insights that are easy to act on. Users can explore AI-generated stock picks, track trend recognition alerts, and view market sentiment scores all in one place. Prospero's proprietary signals combine qualitative and quantitative strategies, enabling investors to identify both short-term trades and long-term growth opportunities with greater confidence and less emotional bias. Beyond the app, Prospero publishes two Substack newsletters: a bi-weekly Investing Newsletter featuring higher-conviction, smaller portfolio picks (reported 60% win rate vs. S&P 500, beating it by 81% annualized as of mid-2025), and a daily Trading Newsletter covering opportunistic strategies including sector plays, macro-focused trades, and event-based options (27% better returns than S&P 500 across nearly 5,000 picks since 2023). Prospero.ai is ideal for individual investors, active traders, and anyone looking to streamline their due-diligence process. Whether you're a casual investor wanting simplified research or a more experienced trader seeking data-backed confirmation, Prospero provides tools to validate analysis, reduce losses, and accelerate wins—all through an accessible, free app.
