How TheoryOS works
Last updated: 20 August 2026
This page explains how TheoryOS behaves — what happens to what you write, who can see it, and what the AI is and isn't. It's a plain description of the product, not a contract. Our full Terms of Service are being finalised.
Our Privacy Policy covers what we collect and who processes it.
You own what you write
Your business idea, your contrarian belief, the problems you identify, your theory of value, your planned actions — all of it is yours. Building it here gives us no claim over it, and no claim over a business you go on to start.
We store it so you can come back to it, show it to people you've shared it with, send it to our AI provider when you ask for help, and generate the exports you request. That's the extent of it.
We don't train AI models on your theories, and we don't sell them. Our AI provider doesn't train on data submitted through its API either.
What the AI is, and what it isn't
TheoryOS uses AI to suggest beliefs and problems, to stress-test your reasoning, and to help you articulate a theory.
It can be wrong. Treat what it produces as a prompt for your own thinking, not a finding. Check anything that matters.
It isn't advice. Nothing here is legal, financial, investment or professional advice. A theory is a structured argument, not a prediction, and building a good one is not a guarantee that a business will work.
Lesson videos use AI presenters. The scripts are written by people; the on-screen presenter and voice are AI-generated. Each video says so beneath it.
There's a daily limit on AI requests — generous for normal use, there to keep the service responsive for everyone. It's a rolling 24-hour window, so if you hit it, access comes back gradually over the following hours rather than at midnight.
Who can see your work
By default, only you.
People you invite. You can add collaborators to a theory as owner, editor or viewer. Anyone you add sees everything in that theory.
Anyone with a share link. Some pages can be shared by link, and those links are genuinely public — no sign-in required. Anyone who has the URL can open it, and it can be forwarded on. Don't share a link to something you'd mind a stranger reading.
Your instructor, if you tag a theory to their course. Tagging is what makes a theory visible to faculty. You choose whether to tag when you create it, and you can change it later from the theory's topbar.
If you're using TheoryOS for a course
A submission is a snapshot. Your instructor sees the version exactly as it stood when you submitted. Editing afterwards doesn't change what they see — resubmit if you want to update it.
Coursework may become part of your academic record. Once submitted, your institution decides how long it's kept and whether it can be removed. This is the one case where deleting something in TheoryOS isn't enough — ask your institution, and we'll act on their instruction.
Your institution's rules on AI apply. Whether, and how, you're allowed to use AI assistance on graded work is their call, not ours. Check their policy.
Enrollment codes are how people join your section. They're the only thing protecting a course roster, so don't post them publicly. Your instructor can rotate a code at any time, which immediately retires the old one.
Your account
TheoryOS is for people aged 18 and over.
Where your university licenses TheoryOS, you're not charged for it and your access runs alongside their licence.
Keep your own copy of anything important. We keep backups, but you can export your canvas from any step, and it's worth doing for work you can't afford to lose.
