Opes Borsa vs Prosper AI
A Free Signal vs a Full Research Stack
Prospero.ai is a free mobile app delivering AI stock signals powered by institutional data analysis
Prospero.ai is a free iOS and Android platform that uses machine learning models to analyse institutional trading behaviour, options market data, dark pool activity, and social sentiment, generating ten proprietary signals for US stocks and ETFs: five short-term (Net Options Sentiment, Net Social Sentiment, Net Institutional Flow, Dark Pool, Short Pressure) and five long-term (Upside Breakout, Downside Risk, Profitability, Growth, Market Similarity). The platform publishes daily AI-curated stock picks alongside its signal framework and offers investing newsletters via Substack. Core access is free; premium newsletter content carries separate pricing. Coverage is US equities and ETFs.
What Prospero.ai's free signal framework provides
Prospero.ai's strongest claim is genuine: delivering institutional-grade data inputs, options flow, dark pool activity, and institutional positioning signals, to retail investors at no cost. The ten-signal framework is thoughtfully structured, separating short-term momentum and flow indicators from longer-term fundamental and pattern signals. Net Options Sentiment updates approximately every two to five minutes, providing near-real-time signal refreshes for covered instruments.
The platform's focus is US equities and ETFs. Commodities, forex, and global equities outside the US are not covered. Each signal is a data point or composite score; the platform does not generate an autonomous AI research narrative synthesising earnings transcripts and analyst consensus, and it does not include an NLP-driven Sentiment Layer classifying live news flow. The conversational layer is absent. There is no macro calendar integrating economic event context with the signal framework.
Where Opes Borsa's research stack extends the comparison
The Opes Borsa Signal Stack adds the analytical layer around the directional signal that Prospero.ai's score-based framework does not include. The Trend Signal carries a disclosed Signal Confidence Score, a model-inferred price target, an upside percentage, and the realised return since the signal issue date, for equities, commodities, forex, and cryptocurrencies globally. The Sentiment Layer classifies live news flow for each instrument using NLP analysis, a systematic input distinct from options flow or dark pool data. AI Research synthesises insider activity, earnings transcripts, and analyst consensus into an autonomous narrative per instrument. Luna provides conversational access to the full stack. Explore surfaces thematic discovery. The Macro Calendar integrates central bank and economic event context alongside the signal architecture.
Prospero.ai's free access model is its most distinctive structural feature, and it is a genuine differentiator for investors who want a signal layer at zero cost. The scope comparison is about what is added when the full research stack is included alongside the directional call.
