The product
Everything you need to actually understand it.
Lumi talks with you, draws the explanation on a live board, and works from the material you're actually stuck on — so revision stops being reading and starts being thinking.
What's inside
Nine things Lumi does that a textbook can't.
“say it plainly”
Talk it through
Ask in your own words, out loud or typed. Lumi talks back and starts from where you actually are.
▢ → ◯ → ✦
A board that draws live
Diagrams, graphs, rendered maths and generated illustrations appear in step with the speech. Point at any part and ask about it.
PDF → ?
Start from your own material
Attach a past paper PDF, a photo, a file or a YouTube link — at the start or mid-lesson — and Lumi reads or watches it and teaches from that.
line 3 ✗
“Check my working”
Draw your attempt on the pad and Lumi reads the handwriting: what's right, what's wrong, and the exact line it went wrong on.
7/10 → why
Homework, marked
Lumi can set work and mark it with a real mark. Written answers get feedback on the reasoning, not just the final answer.
01 → 05
Five ways to re-explain
Simpler, an analogy, a diagram or a quiz on the board. Change the explanation until it clicks.

Pause actually pauses
The tutor stops and so does the meter. Resume picks up exactly where you left off.
↻ kept
It remembers how you learn
What worked, what didn't, and what to revisit — carried between lessons and brought back at spaced intervals before you forget it.
spec ✓
Your course — and beyond it
Teaching packs reviewed line by line against the spec cover 471 objectives across eight AQA and Edexcel courses. Anything else, just ask.
WHY LUMI
Not another study app.
Lumi doesn’t just give you answers. It helps you understand why, by talking things through, drawing what matters and changing the explanation when it doesn’t click.
“Hang on. Let’s break that down.”
How supply and demand set a price
At equilibrium, the quantity buyers want matches the quantity sellers offer.
What happens if demand rises?
See the answer.
Some things are easier to understand when you can see them. Lumi draws diagrams, maps ideas and makes invisible concepts visible.
A cell is a tiny system
membrane → cytoplasm → nucleus
Forces balance
↑ N □ ↓ mg
No acceleration when the forces are equal.
Area under a curve
∫ 2x dx = x² + C
Integration collects infinitely small pieces.
Show me another example from biology.
Start from the actual thing.
Attach a past paper, a photo of the question, a file or a YouTube link — at the start or mid-lesson. Lumi reads it or watches it, then teaches from that, not a generic version of the topic.
