A 1,000-stock screener with transparent grades, a discounted-cash-flow model and Black–Scholes options math you can audit and change, an under-the-radar screen, and a weekly portfolio review you write down. Every formula is documented, and the engine keeps a dated public record of what it said so its own track record can be checked rather than claimed.
Your holdings, decisions and theses are stored in your browser — they are never sent to a server.
