How to plug in your
Personal Investor.

A Personal Investor is an autonomous AI that trades one stock, on one strategy, on your brokerage account. You keep custody of the money. It sends the buy and sell orders. Here's how to wire it up.

What you're renting

Think of it as hiring a quant — one that never sleeps.

Every Personal Investor is a specialist. It trades one specific S&P 500 ticker using one specific algorithm (SMA crossover, RSI mean-reversion, Donchian breakout, and more). Its 12-month backtest — every entry, every exit — is public before you pay a cent.

The AI runs on our servers. It watches the market during trading hours, and when its signal fires, it sends a buy or sell order through your broker's API. Your money never touches us. Ever.

You keep 100% of the profits. During the 30-day trial and forever after.

The full walkthrough

Five steps. About five minutes.

01
Step 01 · 30 seconds

Create your Personal Investors account

Click Sign in in the top nav and create a free account with your email. No card required. You'll land on the marketplace immediately.
02
Step 02 · 2 minutes

Pick a Personal Investor

Open the Marketplace. Every Personal Investor shows its 30-day ROI, win rate, max drawdown, and the underlying strategy. Click into one you like to see the full 12-month backtest, the equity curve, and every single trade the AI made on real S&P 500 prices.
Beginner tip: Look for a win rate above 55%, drawdown under 15%, and at least 8 trades in the past year. Consistency beats a single lucky trade.
03
Step 03 · 10 seconds

Start the 30-day free trial

On the strategy detail page, click Start 30-day free trial. This reserves that AI for your account — no charge, no card. It won't actually trade anything until you plug in a broker.

Step 04 · 3 minutes

Connect your brokerage

Go to Brokers. Alpaca is the fastest and free — you can sign up at alpaca.markets, generate an API key in Home → API Keys → Generate, and paste the Key ID + Secret into our form. Pick Paper mode first (fake money) and click Test connection — you'll see your Alpaca account balance if it worked. Then hit Save.
Other brokers: Interactive Brokers, TradeStation, and Tradier are in beta — you can save credentials now and we'll wire them up as they finish OAuth. Schwab and E*TRADE are on the roadmap.

Step 05 · ongoing

Watch it trade

On the next market open, your Personal Investor is live. It monitors {the ticker} tick-by-tick and executes buys and sells directly on your Alpaca account. Track P&L on your Brokers dashboard.
During the 30-day trial: keep every dollar it earns. If you don't buy, the AI disconnects and stops trading. No auto-renew.
After you buy: the AI runs forever on your account. Flip to Live mode when you're ready for real money, and add unlimited additional brokerage connections.

Don't see your broker? Tell us — we prioritize by demand.

You stay in control

Four things we can't do.

We can't move money.

Your brokerage API keys only permit orders. Deposits and withdrawals are locked to you. Your cash never leaves your broker.

We can't trade other tickers.

Each Personal Investor is scoped to one stock. It cannot buy anything else on your account, period.

We can't override your kill switch.

Disconnect the broker on your dashboard and every AI stops immediately. No approval, no delay.

We can't hide the record.

Every backtest trade is public. Every live trade lands in your brokerage — the same statement your accountant sees.

Ready? Pick a Personal Investor.

Free for 30 days. You keep every dollar it earns. If you like it, own it forever for a flat fee.
