# LINE

FatCat is available in LINE.

In LINE, you trade through the [AI Assistant](/docs/ai-assistant/ai-assistant.md). Chat with it to manage your portfolio, research the market, strategize, and prepare your trades in plain language.

### How it works

When you're ready to trade, the assistant builds the transaction for you. It then hands you off to the [FatCat Web App](/docs/fatcat-web-app/fatcat-web-app.md), where you review, sign, and execute — nothing runs until you approve it.

You can also open the FatCat Web App directly in LINE at any time to trade, view charts, and manage your wallet.

LINE never gets your seed phrase and never signs transactions — every trading action requires your approval.
