About Quant-Builder.ai
Quant-Builder.ai is a no-code platform that enables retail investors to build, backtest and automate machine learning stock prediction models without writing code. Users can train models on 30 years of point-in-time daily data across more than 3,000 US stocks, selecting from 750+ trainable features including technicals, fundamentals, macroeconomics and sector correlations. The platform supports walk-forward backtesting to evaluate strategy performance on out-of-sample periods, reducing look-ahead and survivorship bias. Each morning, models rescore the entire stock universe and deliver confidence-ranked daily picks that can be executed directly via connected Alpaca brokerage accounts or reviewed manually. Portfolio backtesting allows users to simulate multi-model strategies across historical market regimes such as bull, bear, recession and recovery. Specialized models can be trained on predefined universes like the QB100 or any of 11 sector Top-100 indexes, enabling users to focus on familiar market segments. An AI assistant trained on user model data provides plain-English guidance for feature selection, backtest interpretation and strategy optimization.
