The work happens
while you trade.

You have the courses. The tools. The strategy. Yet in the moment, the same mistakes find their way back.

Good questions.
Clear answers.

Does it place trades?

No. magnum opus is read-only. It never places trades, changes orders or manages positions. You stay in control of every trading decision.

Which brokers does it support?

Currently, Topstep (TopstepX) is the only supported connection. Access is read-only: it can never place, change or cancel trades.

Is my data private?

Your journal, trades, screenshots and chats are stored on your own computer, not in the cloud. Your broker API key is kept in your computer’s secure keychain. magnum opus reads your TopstepX account but can never place, change or cancel trades. When you use the AI, your message and charts are sent through our AI service to Anthropic to generate the reply. We don’t store message content, only usage counts (prompts used and cost) for your plan limit. Economic calendar and news come from public sources.

What counts as a prompt?

A prompt is one message you send to the copilot, a day review, or a journal fill from screenshots. Tilt checks and the morning briefing don’t count. Basic includes 50 prompts a week; Pro includes unlimited prompts, subject to fair use.

Does it work on Mac and Windows?

Yes. magnum opus is a desktop app for Mac and Windows. Installer access is password-protected. Release-specific system requirements will be included with each download.

Can I cancel anytime?
