Investment Co-Pilot
An autonomous agent implementing the Simple, Cheap, Safe, and Easy philosophy, based on the work of John Y. Campbell.
Your personal guide to avoiding expensive financial mistakes.
How It Works
1. Discovery Phase
The agent learns your complete financial context through a guided conversation:
- Age & Region (US/EU)
- Goals (Retirement, Legacy, Liquidity)
- Wealth Context (Debt, Home, Savings)
- Risk Tolerance & ESG Preference
2. Safety Rules
Rigorous rules from Campbell's "Fixed" protect you from common mistakes:
- Debt Rule: No investing with high-interest debt.
- Liquidity Rule: Build 3 months cash first.
- Housing Rule: Adjusts for homeownership risk.
- Fun Bucket: Quarantines speculation.
3. Your IPS Document
Receive a formal Investment Policy Statement — your personal roadmap:
- Exact Asset Allocation (Equity/Bonds)
- Specific Low-Cost ETFs (VT, VWCE)
- Rebalancing Rules (5% drift threshold)
- Panic Protocol (what to do in a crash)
Grounded in Research
The agent's logic is strictly based on the principles of modern household finance, specifically the work of John Y. Campbell.
