Cresori does the math
Multi-currency at the right FX date, TWR & MWR, attribution and dividends — computed automatically, since inception.
Understand & act
See what's driving your returns, what dividends are coming, and where to rebalance — across every account.
Finally know why your returns happened.
Most tools show you a number. Cresori breaks it down — which holdings, sectors, currencies and decisions drove your performance, and which dragged it. The story behind the line.
- ✓Contribution by position, sector and currency
- ✓Time-weighted vs money-weighted returns side by side
- ✓FX effect separated from price effect
Everything you need to understand your portfolio

Your portfolio is nobody's business but yours.
Cresori is local-first. Your trades, positions and balances live on your own machine — not on our servers. Connect to Interactive Brokers through your own Gateway; nothing is uploaded. AI features send only a summarized context, and only when you ask.
“I built Cresori because I wanted to know how my own IBKR portfolio was really doing — across currencies, shorts and options — without handing my data to anyone. The free tools couldn't tell me why. So this is the tool I wished existed: honest numbers, on your own machine.”
Your portfolio, explained by AI.
Attribution narratives in plain language, periodic reports written for you, and a chat that actually knows your holdings. Bring your own API key, or use included credits.
