Who Should NOT Use This
- Investors seeking a full brokerage or trading platform — Prospero.ai only provides signals and analysis — it does not execute trades or hold assets, so users need a separate brokerage account.
- Users who want fully transparent, independently audited performance data — Performance claims are self-reported by the company and may not reflect real user returns after fees, slippage, and timing differences.
- Desktop-first professional traders needing advanced charting and order management — Prospero.ai is primarily a mobile app focused on signals and picks, not a full desktop trading suite with technical analysis tools and order execution.
- Crypto or forex traders — The platform focuses on stock and ETF analysis — there is no indication of cryptocurrency or forex market coverage.
