# Intro

> Finny is an AI trading assistant. You describe a trading idea in plain English; Finny generates Python strategy code, runs backtests, and helps you iterate — all from your terminal.

Source: https://finnyai.tech/docs

Finny is built for traders and developers who want to move from idea to inspectable algorithm without abandoning the terminal. Generated code stays open and reviewable, backtests run against real historical data, and broker connections — when you choose to add them — sit behind explicit configuration on your machine.

## What you can do with Finny

- **Generate strategies**: Describe an idea in natural language. Finny writes complete Python strategies and saves them to your workspace.
- **Backtest with real data**: Run `/backtest` to simulate strategies against historical market data via `yfinance`.
- **Connect brokerages**: Link Alpaca or Binance for paper or live workflows. Credentials stay on your machine.
- **Bring your own key**: Use Claude, OpenAI, Gemini, or a local model. Configure via `/init`.

## Quick start

```bash
npm i -g finny
finny
```

On first run, Finny walks you through picking a provider and pasting an API key.
