Prospero.ai

Free

Prospero.ai is a free app that sends you AI-driven stock signals. It reads institutional trading data and turns it into simple bullish or bearish alerts you can scan in minutes.

Prospero.ai sits in finance. It pulls data from options markets, dark pools, and short interest to create ten proprietary signals. The app runs over 10,000 machine learning models on more than 100 million data points. You get a mobile interface that color-codes stocks by short-term and long-term outlook.

The core tool is free with no subscription required. There are paid newsletters if you want daily trade ideas and model portfolios, but the signals themselves cost nothing.

It is built for retail investors who want institutional-style data without the institutional price tag. It is not built for deep fundamental research or buy-and-hold dividend tracking.

Open it if you want fast, free signals to screen stocks. Skip it if you need full coverage of small-cap stocks or detailed earnings analysis.

It fits when you need quick reads without paying upfront.

• Casual investors seeking due diligence research: You get a second opinion on a stock in two minutes. You still do your own homework before buying.
• New investors learning equity markets: The app defines terms inside the interface. You learn what "Net Options Sentiment" means as you use it.
• Users frustrated by paywalled alternatives: Every competitor charges for signals this deep. Here you pay zero.
• Those who want quick, readable market signals: The screen shows green, yellow, or red. You do not parse spreadsheets.
• Users wanting zero-cost signal feeds: You get real-time data without entering a credit card.
• Investors who treat signals as screens, not decisions: You use the alerts to narrow your list. You pick the final purchase yourself.
• Those with very limited time for daily market checks: The app is designed for two-minute sessions. You check, you move on.
• Day traders tracking immediate market movers: The signals update through the day. You watch for breakout alerts.
• Long-term investors screening for momentum stocks: You filter by long-term bullish buckets. You build your watchlist from there.
• Active retail traders who can monitor signals throughout the day: The app pushes updates. You act on momentum as it builds.

These are what you notice after a week of checking.

• Actually free with no required subscription: You download and start. No trial clock runs down.
• Visually intuitive interface: The color system and pentagram read fast. You spend less time navigating, more time deciding.
• Quick to check: Two minutes and you have scanned your watchlist. The app respects your schedule.
• Clear terminology definitions: Tap a signal name and you see what it measures. You learn while you invest.
• Teaching tools and livestreams: You do not just get picks. You learn why the model sees what it sees.

The path is short.

1. Download the iOS or Android app and create a free account.
2. Browse the default stock lists or search a ticker you already own.
3. Read the ten-signal summary and the short-term or long-term bullish rating.
4. Add promising names to your watchlist for daily tracking.
5. Check the screener for new ideas, or follow the optional newsletters for specific trade setups.

Skip it when these limits block your work.

• Limited company coverage: Many stocks are not yet in the database. You may search a ticker and find no data.
• Confusing individual stock graphs: The charts mix signal history with price action. You cannot tell which line means what.
• Watchlist UX issues: There is no obvious add button. You fumble to build your list.
• Portfolio tracking gaps: Dividend investors and money market fund holders get no useful tracking. You need a second app for income maths.
• Self-reported performance claims: The 218% outperformance number is not audited. You cannot verify it.
• Poor customer service: Users report defensive responses on X/Twitter. You may not get help if something breaks.
