No plugins. No screen-scraping. Just your CSV.

We detect Interactive Investor's format automatically. Multi-currency holdings, dividends, and fees are all parsed.
Real return, dividend calendar, and allocation, visible the moment the import finishes.
Am I beating the market, or just depositing more?
Portseido separates your skill from your savings. We compute Time-Weighted Return (TWR), the return your decisions actually produced, alongside Money-Weighted Return (MWR), which includes the effect of your contributions.
Then we benchmark both against S&P 500, NASDAQ, or any index you pick, in your own currency.
See your Interactive Investor dividend income, month by month.
Every dividend is detected from your import and projected forward. See the calendar by timeframe, by holding, or by currency, plus your projected annual income and how it's growing year over year. Prefer a dedicated dividend-only view? See the Interactive Investor dividend tracker.
Your full Interactive Investor allocation, at a glance.
Portseido turns your complete Interactive Investor portfolio into one clear allocation chart. Slice by holding or asset class, and spot over- and under-weighted areas instantly.
