TrendSpider
Automated trendlines · AI pattern detection · multi-timeframe analysis
4.6 / 5
$33/mo (Basic) · $65/mo (Elite)
TrendSpider automates the most time-consuming part of technical analysis: drawing trendlines, finding support/resistance, and identifying chart patterns. Its Raindrop Charts and automated multi-timeframe analysis can scan hundreds of charts in seconds, flagging patterns (bull flags, cup & handle, head & shoulders) without manual charting. The AI scripting language lets you build and backtest automated strategies without coding.
Highlights
Limitations
Danelfin
10-day AI score · 900+ features per stock · explainable AI
4.4 / 5
Free (basic) · $49/mo (Pro)
Danelfin uses explainable AI to score every US and European stock from 1–10 based on its probability of beating the market over the next 10 days. The platform analyzes 900+ technical, fundamental, and sentiment features per stock to generate the score. Unlike black-box AI, Danelfin explains which factors drove each stock's score — making it useful for both screening and research. The free tier covers all US stocks with basic AI scores.

TradingView AI Features
Pine Script AI generation · AI-assisted alerts · Smart Alerts
4.3 / 5
Included in Essential ($14.95/mo)+
TradingView has quietly integrated AI across its platform. Pine Script AI lets you describe a strategy in plain English and generate working Pine Script code automatically. Smart Alerts use AI to detect pattern completions and condition triggers. The AI screener feature can filter 5,000+ stocks using natural language queries. For traders already on TradingView, these features add meaningful AI capability without a separate subscription.
Highlights
Limitations
Finviz Elite
ML-ranked signals · backtested filters · real-time data
4.1 / 5
$39.50/mo
Finviz Elite adds machine learning-enhanced screener signals, real-time data (vs the free 15-min delay), and backtesting capability to the already-powerful Finviz screener. While not "AI" in the same sense as Trade Ideas or Danelfin, the ML signal overlays help rank screener results by recent pattern success rates. The heat map with AI sector rotation signals is particularly useful for macro-aware traders.
