Stock Expert AI vs. Yahoo Finance
Summary
Both are free. Both cover US stocks. But the AI layer and analysis depth are very different. Here's what you get with each.
If you prefer one clear verdict instead of scattered data, see the product overview.
Pricing
Yahoo Finance: free, with an optional paid subscription (Yahoo Finance Plus) for extra research tools — check Yahoo Finance for its current price. Stock Expert AI: free, no subscription.
AI Analysis
Stock Expert AI: MoonshotScore AI rating, Legends Council, Munger analysis, Moon AI chat. Yahoo: no built-in AI analysis.
Portfolio Tools
Stock Expert AI: OCR portfolio scanner + concentration + risk score + AI diagnostics (educational, no buy/sell picks). Yahoo: manual portfolio tracker.
News
Stock Expert AI: New Journal articles go through source and editorial checks before publication. The dated archive remains available: 5,000+ articles drawing on 200+ outlets (counts as of August 2026). Yahoo: aggregated, continuously updated news feeds.
Data Quality
Stock Expert AI: Figures come from Financial Modeling Prep (FMP). If FMP has no figure for a ticker, a price or fundamental may come from a Yahoo Finance fallback, or a price from an Alpaca fallback. SEC EDGAR is used only for filing links and company identity details (legal name, address), never for figures.
