The people who
grade AI's picks
A verification site where we grade ETF picks made by 4 AI agents using actual 30-day and 90-day returns. We publish both correct and incorrect picks.
Why we built this
Most Korean ETF content ends with “this month's pick”. Why that decision, whether the previous month was right, and how we corrected when wrong rarely get recorded.
This site operates on the opposite principle. Monthly ETF analysis is just one line of the result. 80% of pages are the library of decision basis · actual result · post-mortem.
When we're wrong, we don't hide it. April's SMH cut recommendation that turned into +9~10% rally is permanently logged in Missed Museum. We believe trust comes from reproducible reasoning, not raw accuracy.
Operator profile (anonymous)
This site operates under a no face / no real name principle. Trust comes from reproducible reasoning + track record, not personal identity.
- Solo full-stack developer — Next.js · TypeScript · Python · Supabase · GitHub · full-stack infra + automation built directly
- Multiple GPT · Claude usage workshops — methodology to use generative AI as a system design partner, not just a productivity tool
- This site is the empirical case — running 4-AI debate consensus on ETFs as the largest demonstration of AI-as-thinking-partner
Operating structure
- Headcount: 1 (dev + ops + content unified)
- Founded: April 2026

- Stack: Next.js · Supabase · Vercel · Claude · GitHub · Make
- Cadence: Monthly ETF analysis (1st of each month 09:00 KST) + Weekly macro (every Monday)
Our limitations (honest acknowledgments)
- 1. 4-AI consensus has collective bias. All four can misread the same data the same way.
- 2. This analysis is simulation based on past patterns and does not guarantee future returns.
- 3. SPY/QQQ April benchmarks are estimates. Will be replaced with measured values.
- 4. 1-person operation means whether we miss monthly post-mortems is the biggest trust variable. Automation infra under construction.
What we don't promise
- We do not recommend buying or selling specific ETFs.
- We do not provide individual financial advice.
- We do not use phrases like “this will definitely go up”.
