MrDuck - AI Net Worth Tracker

This is not a watchlist. MrDuck is your real-time personal balance sheet. Everything you own in one screen — cold-wallet crypto, US stocks and ETFs, physical gold, multi-currency cash, real estate, and anything else — with live prices, a historical net-worth chart, and an AI assistant tuned to your investor profile. Built for buy-and-hold, not for trading. WHAT YOU GET • Total net worth and per-position value, with today and all-time deltas • Interactive history chart with scrub (1W / 1M / 6M / 1Y / ALL) • Live prices for crypto (CoinGecko), stocks and ETFs (Finnhub), and gold • Multiple private portfolios (e.g. "Me", "Family", "Long-term") • Multi-currency support: USD, MXN, COP, ARS, EUR — daily FX conversion AI THAT KNOWS YOU, NOT NOISE On signup you answer 5 questions about your goal, horizon, drawdown tolerance, experience, and capacity. MrDuck computes your Risk Score (0–100) and builds a system prompt from your answers and your own words. Every AI card speaks your language and your strategy: • Risk Score — how risky your portfolio is today vs. your target • Allocation — how your wealth is split and what adjustments to consider • Daily Read — a calm summary of the day's moves, naming winners and losers Want even tighter control? Edit your system prompt directly from Settings. PRIVACY BY DESIGN • You enter your own positions — MrDuck never connects to your exchange, bank, or wallet • Each user only sees their own data (Row-Level Security in Postgres) • No ads, no data selling BILINGUAL FROM DAY ONE English and Spanish baked in. The app picks up your phone's language and applies it across every screen and every AI response. WHO IT'S FOR • You hold crypto in a cold wallet and it's tiring to open 4 apps to know your total • You hold US stocks or ETFs and Latin American assets and want one unified view • You track your wealth in a spreadsheet and the prices never refresh • You want an intelligent take on your asset mix without paying an advisor LIMITATIONS (important) • Positions are entered manually — this is intentional. We don't link to banks or exchanges • AI commentary is informational only, not financial advice • You need an internet connection for live prices; data is cached on your device — "This is not a watchlist." If you read this far, you probably already know why.
