Turn a stock, forex or crypto chart screenshot into clear AI technical analysis. Understand the trend, support and resistance, review entry and stop levels, and ask follow-up questions about the reasoning. Choose a screenshot or photograph a chart on another screen. In seconds you get: • Bias and confidence — bullish, bearish, or honestly neutral, with a confidence score • The levels that matter — entry, target, and stop, justified by the visible structure • Risk : reward, computed from those levels • The “why” — a plain-language rationale referencing what is actually on the chart Tuned to how you trade. A short setup adapts every read to your markets, timeframe, and style — a scalper and a swing trader get different reads of the same chart. Go deeper with Chart AI Pro: • Detailed structural analysis, evidence, alternatives, and invalidation • Multi-timeframe synthesis across 2–3 charts • Review your own entry, stop, and target against visible structure • Update an earlier read with a newer chart • Unlimited follow-up questions on every read • Saved Levels and full searchable History Chart AI supports English, German, Spanish, French, Italian, Dutch, Turkish, Japanese, Korean, Arabic, and Brazilian Portuguese. AI analysis answers follow your device language. A Chart AI Pro subscription is required after onboarding to use the analysis features. No account is required. No free trial is offered. IMPORTANT: Chart AI provides educational technical analysis of chart images. It is not financial, investment, or trading advice; AI reads can be wrong. Trading involves substantial risk of loss — never trade money you cannot afford to lose. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
