Show IH: I built an AI trading journal that scores discipline, not profit
Hey IH! 👋
I've been trading stocks for a few years and kept running into the same problem: I'd have a solid strategy, but the moment the market dipped, I'd panic sell. Every time. Then the price would bounce back and I'd kick myself.
The problem wasn't my analysis — it was my discipline. And I realized most traders have the same issue.
So I built KeepRule (https://keeprule.com) — a trading journal where an AI scores your discipline, not just your P&L.
How it works:
- Record — Before each trade, log your thesis AND your emotional state
- Refine — Over time, your wins and losses become patterns. The app helps you extract personal trading rules (like "never risk more than 2%" or "don't trade on FOMO")
- AI Discipline Score — An AI reviews each trade and scores whether you followed your own rules
The insight is simple: if you consistently follow good rules, profits follow. But most tools only track the money, not the behavior.
I also added a knowledge base with principles from 28 legendary investors (Buffett, Munger, Graham, Lynch, etc.) so you can learn from the best.
Here's a short explainer video I made: https://www.youtube.com/watch?v=DXWyrXoNYxM
Tech stack: Nuxt 3 + Go-Zero backend, AI scoring via Claude API
Would love feedback from fellow founders. What would make this more useful for you?
Discipline over raw P&L is the right metric to optimize for early on — most blown accounts come from process breakdowns (revenge trading, oversizing) not from picking the wrong stock. On the broker side, execution quality and fee structure end up mattering just as much as any journaling discipline once you're trading enough volume to actually test a strategy; I put together a moomoo vs Interactive Brokers breakdown recently covering exactly that: https://www.lowrisktradesmart.org/en/blog/moomoo-vs-ibkr
"Using AI to track the emotional state and discipline of a trader is a unique pivot from the usual profit-only trackers—helping people extract their own 'personal rules' is where the real value is. Since this is such a niche but powerful application of AI, there’s a competition where you can submit this project—entry is $19 and winner gets a Tokyo trip. Prize pool just opened at $0. Your odds are the best right now. It would be great to see how this 'Discipline Score' concept resonates with a larger audience!"
