Every strategy races the index.

Sleeve is an AI trading app for stocks and crypto. You build a strategy from simple blocks, then watch how it does against the index.

Sleeve shows you whether each idea you trade is keeping up with the index.

One screen for every strategy you run.

You see stocks and crypto side by side. Each strategy gets its own sleeve, drawn next to what you'd have had by just holding the index.

Rules you can read

Every strategy reads as a plain English sentence. Change a number and the sentence changes too.

A ghost for every sleeve

The dashed line shows what you'd have had holding the benchmark instead. If a sleeve can't keep up, you'll see it.

Start on paper

Run a strategy on paper money first and see how it behaves.

Turn an idea into a sleeve.

Describe your idea in your own words and Sleeve turns it into rules. You can test them on past prices, then run them on paper.

  1. 1
    Say it in plain words

    Describe it like you'd explain it to a friend. The AI writes it up as rules you can read.

  2. 2
    Adjust the blocks

    Each rule is a block you can change. Edit one and the others update to match.

  3. 3
    Test it on past prices

    See how the rules would have done on past prices, with costs, next to the benchmark. It's a simulation of the past, so it can't tell you what happens next.

  4. 4
    Race it with paper money

    Run it on today's prices with paper money and watch it against the benchmark.

Sample screens with simulated paper data.

Every sleeve runs against a ghost.

The ghost is what you'd have had by just holding the benchmark. You'll see straight away which sleeves keep up with it and which don't.

Four AI desks watch the market.

The desks read prices, filings, earnings, insider buying, news and social posts, looking at days of data at a time. When a paper sleeve trades, a desk explains what happened. They don't tell you what to buy or sell.

Market scan

Watches prices and volume across stocks and crypto, and flags what's changed.

Risk

Sizes each trade and stops one sleeve from crowding out the rest.

News and filings

Reads company filings, earnings calls and insider buying, and sums up what's in them.

Social signals

Tracks what people are saying about a stock or coin, and when the mood shifts. It's one input the desks weigh with the others.

Questions

When does Sleeve open?

Sleeve's still being built and isn't available yet. Join the waitlist and we'll email you when it opens.

Can I trade real money with it?

Not yet. Sleeve is being tested with paper money only. We plan to let you connect your own broker or exchange, but that depends on a legal review in Australia.

Does Sleeve hold my money?

No. It's built so your money stays with your own broker or exchange, and the key Sleeve uses can't withdraw.

What's a sleeve?

It's one strategy with its own rules, its own share of your money and its own ghost to race. You can run several side by side.

Is this financial advice?

No. Sleeve doesn't tell you what to buy or sell. The AI desks only explain what a paper strategy did and which rule caused it. Information on this site is general in nature.

Which markets does it cover?

Stocks, ETFs and crypto. We're still confirming which markets and brokers will be there at launch.
