The other side of your trade has a data center. Your AI has a chat box.

Your AI is smart. It just has nothing to trade on.

is this a good entry?

Yes! This looks like a strong setup.

  • Data

    It answers from memory.

    It has never seen a price.

  • Compute

    Your laptop is not a cluster.

  • Trading

    Your laptop went to sleep at 9:31.

    So did the strategy. The market did not.

Research it, test it, run it. Your AI does the thinking, our cloud does the compute, your broker holds the money.

FAQ

Your AI, your broker, your call.

Will my AI make things up?

Not the numbers. The AI sends the rules, the server computes them on its stored history, and the results come back into the chat.

Our prices, bar by bar, on the public verify page.

Do you trade for me?

No. We never decide, size or manage a trade.

Coming to QuantGPT Pro: the runner will host your own code and send its orders to your own Alpaca account, under your keys. We never decide a trade. It opens after review.

Is my money safe?

It never leaves your broker. There is no balance to hold and no wallet to drain.

Cards are held by Stripe.

What does it cost?

The Free plan gives 5 backtests and 5 AI calls for the life of the account, with no card. QuantGPT is $49 a month with 500 AI calls a day, and QuantGPT Pro is $149 a month with 1,500 a day. Both paid plans start with a 3-day trial on the plan's full daily limits.

Does it work with my AI?

Claude, ChatGPT or any MCP client. For QuantGPT the URL is https://terminal.quantgpt.co/mcp and the sign-in needs no key.

Custom MCP apps come with ChatGPT's developer mode, which OpenAI offers to Plus, Pro, Business, Enterprise and Education accounts, on the web.

Do I need to write code?

Not for QuantGPT. You pick a documented strategy and set its parameters, build criteria in the terminal, or connect Claude or ChatGPT over MCP and ask in plain English.
