Its stated ambition is to narrow the gap between institutions and individuals — the company frames its mission as \u003ci\u003eleveling the playing field in investing\u003c\/i\u003e, and adds: \u003ci\u003eAt Prospero.ai, we believe everyone should get a fair opportunity to invest like Hedge Funds.\u003c\/i\u003e The method is deliberately reductive: aggregate institutional and market data, then compress it into ten readable signals instead of a wall of indicators. Five signals cover a long horizon of roughly two months to two years: Upside Breakout, Downside Breakout, Profitability, Market Similarity and Growth, summarised by a Long-Term Signals Overview. Five cover a one-to-two-month horizon: Net Options Sentiment, Net Social Sentiment, Net Institutional Sentiment, Dark Pool Rating and Short-Pressure Rating. The publisher's own definition is explicit: \u003ci\u003eWe use data science, machine learning, and artificial intelligence to create 5 short-term and 5 long-term signals that can be used to rank US stocks and ETFs against each other.\u003c\/i\u003e The signals are comparative — they rank securities against one another — and coverage stops at US-listed stocks and ETFs. Inside the app you search by ticker or company name, follow four Our Picks lists (Long Term Bull, Short Term Bull, Long Term Bear, Short Term Bear), read a Daily Screener, keep a watchlist that alerts you when a signal changes, and work through an in-app learning guide mirrored by an online Learning Center documenting each signal. A 'Daily Stock Picks' feature is still flagged as coming soon. The publisher claims 100+ million data points analysed, 10,000+ AI\/ML models, 13+ years of institutional predictive-pipeline experience, and picks outperforming the S\u0026amp;P 500 by 12.9x; results published since 2023 cite roughly 5,000 picks, a 54% success rate and 27% more return than the index, with 60% for the 2025 cohort. All are publisher claims, framed by its own disclaimer that these are model outputs, not actual trading results. Intellectual property is presented as jointly held with NYU. The app executes nothing: Prospero.ai is neither a broker nor an adviser. Two paid Substack newsletters and a Discord community with direct access to the CEO sit alongside it.\u003c\/p\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch3

Google Play's Data safety card states that no data is shared with third parties, that data is encrypted in transit, and that users can request deletion. Apple's App Privacy card lists usage, crash, performance and other data as not linked to the user's identity. Account deletion is available in the app, under Profile \u0026gt; Account Settings \u0026gt; Delete My Account, or by support ticket.\u003c\/p\u003e\n\u003ch3\u003eReuse rights\u003c\/h3\u003e\n\u003cp class=\"justify\" style=\"color:var(--gv3-ink-2);margin:0\"\u003eNothing is published on how collected data is used, or on what users may do with the signals and screener output they consult: the privacy policy and terms are not readable, so no licence, reuse or redistribution clause exists to cite. The verifiable declarations are limited to the store cards. Google Play lists \u003ci\u003ePersonal info, App activity and 2 others\u003c\/i\u003e as collected categories and states 'No data shared with third parties'. Apple reports usage, diagnostic and performance data, not linked to identity. The website itself is instrumented with Google Analytics and with Amplitude, whose session replay is active at 100% sampling. Newsletter sign-up and billing are handled by Substack, under Substack's own policies rather than Prospero.ai's.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"trust-card\"\u003e\n\u003ch3\u003eData retention \u0026amp; training\u003c\/h3\u003e\n\u003cdiv class=\"kv\"\u003e\n\u003cdiv class=\"k\"\u003eRetention summary\u003c\/div\u003e\n\u003cdiv class=\"v justify\"\u003eNo retention period is published. The privacy policy that would set one is a Termly embed with no readable content, so nothing states how long account, usage or diagnostic data is kept, nor whether it is anonymised at any point. The only documented mechanism is deletion at the user's initiative: the account can be deleted in the app, under Profile \u0026gt; Account Settings \u0026gt; Delete My Account, or through a support ticket, and Google Play's Data safety card confirms that users can request deletion of their data. One consequence is worth noting: deleting the Prospero.ai account does not delete the associated Substack account, cancel a paid newsletter subscription, or unsubscribe the user from the newsletter, which has to be handled separately with Substack.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"col\"\u003e\u003cdiv class=\"trust-card\"\u003e\n\u003ch3\u003eHosting summary\u003c\/h3\u003e\n\u003cp class=\"justify\" style=\"color:var(--gv3-ink-2);margin:0 0 14px\"\u003eNo hosting country, region or jurisdiction is published. The documents that would state it — the terms and the privacy policy — are Termly embeds whose content has been deleted, so nothing can be established about where user data is stored or under which law it is processed. Only a few technical facts are verifiable from the outside: the website is built on Webflow and served behind Cloudflare (AS209242, anycast), which says something about the delivery of the marketing site but nothing about the app's back end. Google Play's Data safety card declares that data is encrypted in transit. The two newsletters are hosted and billed by Substack, so subscriber and payment data sits with Substack under its own terms. Readers with a data residency requirement should treat this as unresolved rather than as an implicit US-only arrangement.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/section\u003e\n\u003csection class=\"block watch\" id=\"watch\"\u003e\u003cdiv class=\"head\"\u003e\n\u003cspan class=\"eyebrow\"\u003eWatch-outs\u003c\/span\u003e\u003ch2\u003eThings to keep in mind\u003c\/h2\u003e\n\u003cp class=\"lead\"\u003eRisks and trade-offs to weigh before adopting Prospero.ai.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cul class=\"brand-list\" style=\"grid-template-columns:repeat(2,1fr);display:grid;gap:12px 24px\"\u003e\n\u003cli\u003eNo contractual safety net: the terms, privacy policy and cookie policy are empty Termly embeds, so you accept conditions you cannot read\u003c\/li\u003e\n\u003cli\u003eNo postal address and no legal or privacy email address are published, which leaves no formal channel for a dispute or a data request\u003c\/li\u003e\n\u003cli\u003eThe headline performance figures are model results rather than real trading results, and reading them as a track record would be a mistake\u003c\/li\u003e\n\u003cli\u003eThe tool analyses, it does not advise: no recommendation is personalised to your situation, your horizon or your risk tolerance\u003c\/li\u003e\n\u003cli\u003eSignal-change alerts on a watchlist reward frequent checking, which can nudge a long-term investor towards over-trading\u003c\/li\u003e\n\u003cli\u003eDelegating judgement to a score is a real risk: the publisher itself says the app should not be your only source of market intelligence\u003c\/li\u003e\n\u003cli\u003eThe website runs Amplitude session replay at 100% sampling, so browsing behaviour is recorded, and the \/about-us page contradicts itself on the leadership team's roles\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/section\u003e\n\u003csection class=\"block\" id=\"setup\"\u003e\u003cdiv class=\"head\"\u003e\n\u003cspan class=\"eyebrow\"\u003eSetup\u003c\/span\u003e\u003ch2\u003eSetup \u0026amp; Integrations\u003c\/h2\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"setup-grid\"\u003e\n\u003cdiv class=\"setup-card\"\u003e\n\u003ch3 style=\"font-size:15px;margin-bottom:10px\"\u003eTechnical difficulty\u003c\/h3\u003e\n\u003cp class=\"justify\" style=\"color:var(--gv3-ink-2);margin:0 0 14px\"\u003eVery low.

On substance, the app delivers what it describes: ten signals, each documented individually in a public Learning Center, an in-app learning guide, four curated pick lists, a daily screener and signal-change alerts, all on a free iOS and Android app with no paywall at sign-up. Published performance figures are dated and carry both a methodology note and a disclaimer stating they are model outputs rather than real trading results — a caution many comparable tools skip. Press coverage in Fast Company, USA Today, Forbes, Yahoo Finance and VentureBeat is real, and direct access to the team through Discord and livestreams is unusual at this price point, which is to say none. The reservations are equally clear. The three legal pages — terms, privacy policy and cookie policy — are Termly embeds whose documents have been deleted, so there is no readable contract, no GDPR statement, no retention rule and no hosting disclosure. No postal address, legal contact or privacy contact appears anywhere on the site. Coverage stops at US-listed stocks and ETFs; there is no web version, no API and no documented integration. The publisher itself advises against using Prospero.ai as a sole source and positions it for intermediate to expert investors, and one headline feature, Daily Stock Picks, is still marked as coming. The natural fit is a self-directed retail investor who already has a tested method and wants a quantitative second opinion on US equities. Because the entry cost is zero, evaluating the app costs only time.
