Hi Hunters, Six months ago I gave up trying to make Excel work for stock research. Today I'm launching the tool I built instead. For years I had ideas like "buy stocks bouncing off their lows" but no way to test them without writing Python or paying for Bloomberg. I'd cook something up in Excel, decide it "looked good", and trade it — only to realize months later I had no idea if it actually worked or I just got lucky. Existing tools each fail a different way: Bloomberg is priced for institutions, Quantopian-style platforms are either gone or code-required, and ChatGPT will happily write you "a momentum strategy" but the numbers are hallucinated. It can't actually run a backtest. Alpha Builders fills that missing middle: - Describe what you want in plain English. The AI picks from 75 factors. - Real backtest against 13 years of US data, 3,000+ tickers, in 30 seconds. - Click "Track this strategy" and we run it forward as a live simulation. Every market close, real prices, real NAV side-by-side with the S&P 500. After a few weeks you actually know if the backtest's edge held up. What I'd most like feedback on: - Did the AI understand your first idea, or did it misunderstand? - Does the simulation page feel honest about uncertainty, or too good to be true? - Any factor families you'd want that we don't have? Thanks for taking a look.
