Show HN: A calculus course with an AI tutor watching the lectures with you

[apoogdk]

We're two PhD students in mechanical engineering. We spent years digging through scattered textbooks and YouTube rabbit holes. We figured there could be a better way to learn.

So we wrote a multivariable calculus course entirely in code: 18 lectures, 6 languages. All content and pedagogy are ours. As everything is code, we can feed the LLM the full context of every lecture. Ask a question mid-lecture, it knows what's on the screen, and answers from the actual content.

The recent Coursera/Udemy thread echoed a lot of what pushed us to build this: https://news.ycombinator.com/item?id=46301346

Would love feedback, especially on the tutor.
