Prospero.ai is a free mobile app that uses artificial intelligence to analyze stock market data and generate investment signals for users. It processes over 100 million data points through more than 10,000 machine learning models to produce metrics such as Net Options Sentiment, Technical Momentum, Net Social Sentiment, Dark Pool Activity, and Short Pressure. These signals help identify short-term and long-term stock opportunities by highlighting institutional movements and market trends. The app is available on iOS and Android and integrates with newsletters for additional insights.
The platform offers two newsletters: the Investing Newsletter provides bi-weekly updates on high-conviction portfolios blending qualitative and quantitative strategies, reporting a 60% win rate against the S&P 500 in 2025 and 81% annualized outperformance as of July 15, 2025. The Trading Newsletter delivers near-daily opportunistic picks, including sector plays and event-based trades, with 27% better returns than the S&P 500 and a 54% win rate across nearly 5,000 picks since 2023. Performance claims include 12.9x outperformance relative to the S&P 500, based on simulated results.
Key features include a signals dashboard for real-time stock analysis, ‘Our Picks’ lists focusing on top-performing stocks, and visual representations of complex metrics for quick evaluation. Users can access a learning center for signal explanations and company details via the about page. Testimonials highlight ease of use, time savings in analysis, and improved decision-making, with specific mentions of objective analysis reducing emotional trading and visual tools enabling seconds-long stock reviews.
Prospero.ai differentiates from competitors by offering free access to advanced signals, unlike paid platforms such as TrendSpider, which emphasizes automated charting, or Trade Ideas, focused on real-time scanning. It provides broader signal integration compared to Magnifi‘s conversational AI advisor. Limitations include simulated performance not accounting for trading costs and limited customization options.
The app supports retail investors by democratizing hedge fund-level analysis, founded on the principle of reducing institutional advantages. It analyzes institutional data for market-moving insights to minimize losses and enhance wins. Users report higher win rates and market-beating returns from signal-guided trades.
To use Prospero.ai effectively, download the app, review the learning center tutorials, monitor daily signals for selected stocks, and cross-reference with newsletters before executing trades in your brokerage account.
