Why we built this
Every one of us has stared at a piece of content — a research paper, a dense report, a lecture recording — and felt that specific frustration of knowing the information matters, but not being able to get it in. Not because we weren't trying. Because the content was written for someone else.
The tools that exist today compress information. They summarize it. They reformat it. But none of them ask the one question that would change everything: who is reading this, and what do they actually need? A software engineer reading a pharmacology paper needs a completely different explanation than a medical student reading the same thing. Treating them identically is not neutral — it is a failure.
Lumi is our attempt to fix that. Not for a specific subject, or a specific age group, or a specific institution. For anyone with something they need to understand and a gap between where they are and where the content assumes they'll be. It's open source because this problem is too important to sit behind a paywall.
