Hey r/cseducation!

I've been working on a tool called Hyperbook and wanted to share it here since this community seems like exactly the right audience.

The short version: Hyperbook lets you write interactive student workbooks using Markdown, and it builds them into a fast, modern website your students can just open in a browser. No complicated setup, no LMS required (though it can work alongside one).

Why I built it: I got frustrated putting together course materials in tools that were either too rigid (PDFs, Google Docs) or required way too much overhead (custom web apps, heavy LMS editors). I wanted something where I could just write content in a text file, throw in some interactive elements, and have it "just work."

What it can do:

• 30+ custom Markdown directives for things like code exercises, quizzes, protections, excalidraw diagrams, and more

• A VS Code extension (Hyperbook Studio) with live preview, snippets, and validation — so authoring feels really smooth

• Super fast static output, so you can host it basically anywhere

• Fully open source under MIT — no vendor lock-in, no subscriptions

Who it might be useful for: If you teach programming, algorithms, or really any CS topic and you've ever thought "I wish my course notes were a bit more interactive without me having to become a full-stack dev," this might be worth a look.

I'd love feedback from educators who've dealt with this problem — what features would actually make a difference in your workflow? And if anyone gives it a try, I'm very open to issues/PRs on GitHub.
