Stop guessing.
Know your money.
Finance OS turns your brokerage exports into a complete financial picture. Real P&L, portfolio health grades, tax optimization, and AI insights. All running on your machine, never in the cloud.
Built for the problems self-directed investors actually have
Finance OS replaces scattered spreadsheets and incomplete brokerage apps with one unified system that runs entirely on your machine.
Spreadsheets break as your portfolio grows
Holdings are auto-calculated from your raw transaction history using FIFO cost basis.
No clear picture of portfolio health
Portfolio X-Ray grades your concentration, risk, discipline, and returns with actionable alerts.
Tax season is a scramble every year
Country-aware tax tracking shows your marginal rate, contribution room, and optimization opportunities.
Emotions drive more trades than logic
A built-in rules engine tracks stop-losses, position limits, and cooling periods automatically.
Brokerage apps only show one account
Import from Wealthsimple, Robinhood, Fidelity, Schwab, Interactive Brokers, or any CSV into one view.
You have to trust third parties with your data
Everything runs locally on your machine. SQLite database, no cloud, no accounts, no telemetry.
Six views, each with a clear purpose
Every tab answers a specific question about your portfolio, taxes, or trading discipline.
See your entire portfolio at a glance
