Turn any lecture into nine study formats in under 15 seconds
How Lumo AI's five-agent system reads your source once and produces notes, flashcards, a quiz, a mind map, slides, an audio overview, and more — all graded for accuracy before you see them.
You drop in a lecture recording, a dense PDF, or a YouTube link. Fifteen seconds later you have a complete study kit: structured notes, a deck of flashcards, an adaptive quiz, a mind map, slides, and a two-host audio overview you can interrupt and steer. Here's what happens in between.
One source, nine ways to learn
Most tools give you a single output — a summary, or a chat window. Lumo produces nine distinct formats from the same source in one pass, because different moments call for different formats:
| When you're… | Reach for | | --- | --- | | Reviewing before class | Notes + Summary | | Drilling for recall | Flashcards + Quiz | | Seeing the big picture | Mind map | | Studying hands-free | Audio overview |
Every format is generated from the same verified understanding of your source — so your flashcards never contradict your notes.
The five-agent system
Quality comes from a stateful agent graph, not a single prompt:
- Planner scopes the work and sets success criteria.
- Researcher retrieves and verifies facts against your source.
- Synthesizer drafts the structured output.
- Critic scores the draft 1–10 on accuracy, clarity, and age-appropriateness.
- Refiner fixes whatever the Critic flagged — up to three loops.
Nothing reaches you until it clears the Critic. That's why the output reads like a strong study guide instead of a first draft.
Tuned to your grade
A Class 6 explainer and a university one shouldn't read the same. Lumo calibrates depth and vocabulary to your level — and you can change the reading level on any note at any time.
Drop in a source, pick your level, and study between classes.
