About
ThesisEdge lets anyone — beginner or pro — backtest any stock strategy in plain language. Type something like "DCA $500/month into SPY for 20 years, reinvest dividends" and the app simulates it against 30 years of real S&P 500 data in seconds. No spreadsheets, no code, no expensive quant tools.
The heart of the app is an AI translator (GPT-5-mini) that turns natural-language strategies into precise technical parameters. The simulation engine runs locally on the phone across 30+ years of S&P 500 history, accounting for dividends, splits, commissions and capital-gains tax.
