Prospero.ai

Prospero.ai is an AI stock-picking and investment analysis platform built by New York-based Prospero.ai LLC, founded in 2019 by former hedge fund professional George Kailas with the mission of giving retail investors institutional-grade data analysis on par with hedge funds. Its core is an AI system developed jointly with New York University (NYU) intellectual property, analyzing 100 million+ data points daily and using 10,000+ proprietary models to compress options flow, dark pool trading, social media sentiment, and institutional holdings into 10 interpretable core signals (5 long-term + 5 short-term), generating daily stock picks.

Core Features

• Daily AI Stock Picks: Curated stocks with the strongest signals, offering short- and mid-term long/short rankings
• Signal-Driven Screener: Browse and filter stocks and ETFs by signal strength
• Watchlist Tracking with Real-Time Alerts: Monitor signal changes across your holdings
• Learning Center and In-App Guides: Systematic explanations of the 10 signals, focused on teaching users to read signals rather than black-box picks
• Newsletters: A biweekly Investing Newsletter and a near-daily Trading Newsletter (Substack)

Pricing Model It uses a freemium model: the iOS/Android app is completely free, with no credit card required to access daily picks, the 10 signals, the screener, watchlists, and learning guides; the paid side consists of Substack newsletters, with the Investing Newsletter at about $10/month (annual billing discounted) and the Trading Newsletter price not fully disclosed. The flagship paid product Trade Alerts (real-time trade alerts) is in beta with crowdfunding investors, with pricing undisclosed. Third-party directories commonly cite its low pricing transparency.

Competitor Comparison Compared with Danelfin ($22-134/month), Tickeron ($60-250/month), and Trade Ideas ($127-254/month), Prospero is one of the few mobile products combining completely free access, institutional-grade 10 signals, and an education focus. In WealthBuilderX's real-world testing, Prospero ranked #1 with a 60% hit rate, slightly above Danelfin's 58%. Main weaknesses include: no trade execution, no public API, incomplete stock coverage, no international or crypto markets, and performance data that is mostly company-reported (backtests rather than live trading).

Who It's For Suited to retail and self-directed investors who want institutional-grade research without paying $200+/month subscriptions, swing and day traders who need daily directional signals, and investing newcomers who want to systematically learn market signals. Not suited to professional quant traders who need one-click automated trading or users requiring full global market coverage.

Editorial Review Rating: 4/5. Free plus interpretable plus education-focused forms a genuine differentiator, and it places highly in coverage by mainstream outlets such as Forbes, VentureBeat, and Fast Company as well as in independent tests; deductions come from weak pricing transparency and heavily self-reported performance. When listing, watch for confusion with same-name entities (proposal software goprospero.com, email tool theprospero.ai, a Claude writing plugin) and rely on the official site www.prospero.ai and its positioning as an AI stock-picking app.
