From lecture to slide deck in one pass

There's a reason teachers understand their subject so deeply: they have to explain it. Turning a topic into slides forces the same discipline — you have to decide what matters, put it in order, and say it simply. That act of structuring is where a lot of real learning happens.

Slides as a study tool, not just a deliverable

Most people think of slides as something you make for an audience. But a deck is also a fantastic study artifact: one idea per slide, a clear progression, and nothing to hide behind. If you can present it, you know it.

Generated from your source

Lumo turns your lecture, PDF, or paper into a clean, logically ordered deck in the same pass that produces your notes and quiz. Each slide captures one idea, in your source's own terms — no filler, no invented examples. Use it to:

• Present the topic to a study group (or to yourself, out loud).
• Review the arc of a lecture at a glance before an exam.
• Spot gaps — any slide you can't explain is a slide to go study.

Make it active

Don't just read the deck. Close it, talk through each slide from memory, then open it to check. The slides give you the structure; your voice does the learning.
