Prospero AI is a free AI investing app that turns millions of institutional data points into simple buy and sell signals. It's built for retail investing.

It's an AI stock picking app first, and everything else supports that job.
About Prospero AI
What Is Prospero AI
Prospero AI is an AI stock picking app built for retail investors. It reads the kind of institutional trading data that hedge funds pay heavily for, then compresses it into signals you can scan in seconds. The pitch is simple: you shouldn't need a Bloomberg terminal or a finance degree to spot where money is moving.
The company launched in 2019 out of New York and markets itself as a way to level the playing field for everyday traders. It focuses on signal-driven research rather than raw chart dumps. Two newsletters sit alongside the app, one for investing picks and one for trading, both published on Substack.
The biggest limitation is the one nobody likes to print. Prospero AI shows signals, not guarantees. The app itself says its performance figures come from models rather than trades that were actually executed, which means your real-world results can look very different from the headline numbers. You still make the call, and you can still be wrong. Treat it as a research assistant, not an autopilot.

Key features
AI Stock Signals
Prospero AI distills large volumes of institutional data into signals that flag potential short-term and long-term moves. Each signal aims to show when a stock is gaining strength or losing steam. The idea is to cut the noise you'd normally sift through on a chart.
Daily Stock Picks
Every day the app highlights which stocks its models see as winners and losers, giving you a ready shortlist to scan before you ever open a chart or build your own filter. It's the fastest way to see what the AI is watching.
Proprietary Alerts
You can get notified when signals change for stocks on your watchlist. That means less refreshing and more reacting to actual shifts. If a position starts to move against you, the app tries to flag it early.
Stock Screener
The screener ranks stocks by cumulative signal scores so you can see momentum building or fading. It removes the guesswork of combining indicators yourself, which matters a lot when you don't have years of chart-reading experience behind you. Scan the leaders, skip the laggards.
Watchlist Tracking
Add the stocks and ETFs you care about and track them in one place. The watchlist feeds directly into alerts and signal updates. It keeps your research tied to positions you actually hold or follow.
In-App Learning Guide
A built-in guide explains how to read each signal and build a process-driven approach. It's aimed at people who want to learn investing skills, not just copy picks. The material leans educational rather than promotional.
Pros and cons
Pros
- Free to download and use, with no subscription needed to access the core app.
- Signals translate complex institutional data into plain language for beginners.
- Available on both iOS and Android, so you aren't locked to one phone.
- The learning guide supports skill-building instead of blind pick-copying.
Cons
- Performance figures come from model signals, not real executed trades, so results can differ from your actual experience.
- There's no public API, which rules it out if you want to feed signals into your own tools.
- The app leans on signals alone; it won't replace deeper fundamental research for serious positions.
Frequently asked questions
No. It's an AI trading app in the research sense: it surfaces signals and picks, but you place any trades yourself through your own brokerage.
