Our copyright position

yogi is built from your school's course materials. Here is exactly what that means, and what it does not.

Effective September 8, 2026

We write new questions. We do not republish your course.

Our software reads a block’s official materials to learn what the course teaches — the objectives, the vocabulary your school uses, which session covered what. Then it writes original questions that test those objectives. The output is new writing about the same subject matter, not a repackaging of the source.

Facts and objectives are not what copyright protects; expression is. We take the first and write our own version of the second.

No text is reproduced

A question never carries a handout’s sentences. Our authoring standards forbid it and our review step checks each question against the material it came from before it is allowed into the bank. No figure, slide, image or table from your course is reproduced anywhere in the product — the questions are text, always.

Fresh patients, every time

Where a course uses a case, we do not reuse that case. Every patient in every question is invented for that question: a different age, a different presentation, a different set of numbers, chosen so the question tests the same idea without borrowing the story. A case in a handout is context we read; it is never content we copy.

Citations point back; they do not carry anything across

After you answer, we show you where in your own reading the idea came from — a human label such as “SG2: Urea Cycle · objective 3 · p. 4”. That is a pointer to material you already have, so you can go and read it. We do not serve you the material itself: the source text never reaches your browser, and there is no way to reconstruct a course document out of the citations.

Course materials do not travel

A school’s materials are ingested for that school’s students and are not shared with another school, sold, published, or used as a corpus for anything else. They stay inside the pipeline that reads them.

If you are a school, a course director or an author

If you believe something we have published crosses a line — reproduces your wording, reuses your case, or should not exist — write to the address your invitation came from and tell us which question. We will take it down while we look, and we will tell you what we found. That is a standing offer, not a formality.

What this page is

Our position, stated so it can be argued with — and so a student, a school, or a lawyer can read it before asking. It is not legal advice, and it is not a licence. Questions to the address your invitation came from; these terms are read under the law of the Commonwealth of Pennsylvania.
