Hey PH! I'm William, the maker of KeepRule. I built this because I kept losing money — not from picking bad stocks, but from panic selling good ones. I'd buy based on solid analysis, then sell the moment the market dropped 10%. Every single time, it recovered. I calculated it cost me thousands. The problem wasn't my strategy. It was that I had no system for following my strategy. So I built KeepRule: a tool that helps you document your investment principles (things like "don't sell within 24 hours of a market drop" or "only invest in businesses I can explain in 2 sentences") and then scores whether you actually follow them. The core insight comes from Buffett: judge decisions by process quality, not outcomes. A disciplined trade that loses money is better than a lucky trade that breaks your rules. What you can do with KeepRule: - Browse principles from 26 legendary investors (Buffett, Munger, Graham, Dalio, Lynch...) - Build your own personalized rule set - Log trades and get AI discipline scoring - Track your rule adherence over time I'd love your feedback — especially from anyone who's struggled with emotional investing. What rules do you wish you'd followed?
