The AI Market Companion is a conversational interface that understands financial context. You can ask it anything about the market in plain English — "Show chart and analysis for $NASDAQ:NVDA", "Run technical analysis (RSI/MACD) on $BINANCE:BTCUSDT", "Analyze my portfolio risk, concentration, and opportunities." — and it responds with data-backed answers, charts, technical analysis, and risk-first guidance.
