```table
class: Holding
columns: company, account, shares, avgCost as Avg cost, company.price as Price, value, pl as P/L, plPct as P/L %

## News on what you hold

This is the **portfolio example**: what an AI builds when you tell it
> Build me an app to track my portfolio: my holdings, what I paid, today's price, and tell me when a company I hold puts out news.
Everything here is sample data. Tap a holding to change it, or **+ Add** a new one; value and P/L work themselves out. The forms all work, but this demo doesn't save: that's for your own project. The model is in [[Spec:portfolio]] and the samples in [[Story:portfolio-samples]]; [Data](/dom) has everything, companies included.
## Make it yours
- **In your own project:** connect your AI (see [Help](/help)) and ask it to *import the portfolio example*. It copies the model and the samples, and adds a card on your home page.
- **Change it by talking:** "add a watchlist", "track dividends", "tell me when a price moves more than 5%". Your AI changes the model and the app follows.
This demo is reset whenever d2 is updated: nothing you change here is kept.
