Learn anything.
Ace everything.
Say what you want to learn. Lumi teaches it out loud, writing and drawing on a live board as it explains — taught to your exact course, and happy to be interrupted.
- Half an hour free
- No card
- GCSE, A-Level and beyond
An example lesson, played on the board the app uses.
A tutor that talks
It’s not a chatbot.
It’s a lesson.
A chatbot gives you an answer and leaves you to work out why. Lumi teaches the way a good tutor does: it explains out loud, builds the picture as it goes, notices where you’re stuck and changes the explanation until it lands.
You talk, it talks back
Ask out loud or type. Lumi answers in a voice, at the pace of a person explaining — not a wall of text to scroll.
It draws while it explains
Equations, diagrams, timelines and graphs land on the board at the moment they're said, so the picture and the words arrive together.
Cut in whenever you like
Lost the thread? Say so mid-sentence. Lumi stops, answers, and tries a different way in until it clicks.
- A wave carries energy, not water. The water mostly bobs up and down where it is.
- Hang on — then why do waves crash on the beach?
- Great question. Near the shore the bottom slows the wave down, so it piles up and tips over. Let me draw it.
How a lesson goes
One box. Then a lesson built for you.
There is nothing to enrol in and no course to pick first. Say what you need, attach whatever you’re working from, and Lumi does the rest.
Walk me through question 4 on this paper
PDFPaper 2.pdfIMGmy working.jpg1Ask for anything
A topic, a question, a test on Friday. Attach a past paper, a photo of your working, your notes, slides or a YouTube link.
✓Read Paper 2 · question 4
✓Pitched at A-Level Physics
✓Plan: 4 steps, 2 common slips
2Lumi does its homework
It reads what you attached, researches the topic and writes a plan: the level to pitch at, the order to teach in, the mistakes people usually make.
v = u + at→ 14 m/s
“Start from what you know — u is zero…”3Then it teaches, out loud
Lumi speaks and the board fills in as it goes. Interrupt, ask for it simpler, an analogy, a diagram — or a quick quiz to check it stuck.
Everything a great tutor does
The explaining is only half the job.
The other half is the checking, the marking and the remembering. Lumi does both halves.
Photosynthesis
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
light energy in, glucose out
A live board, not a wall of text
Equations, labelled diagrams, graphs and timelines, written as Lumi says them. Point at any part and ask about just that bit.
Teaches from what you bring
PDFs, photos, Word documents, slides, text files or a YouTube link. If something can't be read, Lumi says so — it never guesses.
3x + 7 = 19
3x = 12
x = 36÷ 3, not × 3
“Check my working”
Write your attempt on the pad. Lumi reads the handwriting and shows the exact line it went wrong on.
Q3: right method, but the units went missing in the last line.
Homework, set and marked
Lumi sets work on what you covered and marks it with a real mark. Written answers get feedback on the reasoning.
What works for you
- · a diagram before the algebra
- · real examples over definitions
- · go slower on rearranging
Remembers how you learn
After each lesson it notes what worked — a picture first, fewer symbols — and picks up from there next time.

Taught to your exact course
Tell Lumi your course once and every lesson is planned against its specification. You see how much of it you've covered — and asking about something off the syllabus is still fine.
Four promises
A confident wrong answer is the one thing a tutor can’t give you.
So here’s what Lumi will never do.
- 1
Make up what it couldn't read.
If a file won't open or a video has no captions, Lumi tells you. It never guesses at your past paper, a quotation or a figure.
- 2
Claim a course it didn't find.
It only names an exam board or a specification it actually located. When it isn't sure, it says so and teaches the topic generally.
- 3
Turn a lesson into a quiz show.
Most of a lesson is explanation, with a real check-in every few minutes. Never two questions in a row.
- 4
Give you a number to game.
No points for showing up. You see how much of your course you've covered and how your marked work is going — nothing you could optimise instead of learning.
Any subject
From your exam board to the 2am rabbit hole.
GCSE and A-Level courses, taught to the specification you sit. University modules. Or whatever you’re simply curious about.
Who it’s for
Built for the person learning. Trusted by the people around them.
Students
Start from your own work
Your notes, past papers, homework — Lumi teaches from them, not a generic version of the topic.
Your course, your board
Lessons planned against the specification you actually sit.
There at 11pm
The night before the test, as patient on the tenth question as the first.
Parents
A tutor's patience, for less
One-to-one, out-loud teaching for a fraction of an hour with a private tutor.
Honest by design
It says when it doesn't know, rather than inventing an answer.
Try it before you pay
Half an hour of real lessons free. No card needed.
Schools
Every student, their own tutor
Each one taught at their level, from the material they bring.
Planned against the spec
Courses mapped to the specification, with coverage you can see.

We'll walk you through it and set up what your students need.
Before you sign up
The four things people ask first.
No card is needed. The free plan is 3 lessons in total — 10 minutes each, with the live board and real-time speech. It is a lifetime trial, not a weekly allowance: the lessons are yours whenever, and they do not reset.
Tell it your board and it teaches to it. The courses checked line by line against the actual specification — reviewed teaching packs covering 471 objectives — are eight AQA and Edexcel qualifications: Edexcel GCSE Maths Higher, AS Maths and A-level Maths, and AQA GCSE Biology, Chemistry and Physics Higher plus AS and A-level Economics. On any other board or subject it will still teach the topic; the packs are simply the part verified against the spec.
No. Revision is not assessed, and no exam board has ever had a rule about how you learned something. The rule is about authorship: work you submit under your own name has to be yours. Lumi is built to explain and to check the explanation landed, not to write the thing you are about to hand in. Coursework and non-exam assessment are where the care is needed, and your school's own policy sits on top of the exam boards'.
ChatGPT also offers study and voice features. Lumi is a dedicated lesson: a live board it draws on while it talks, your own past papers and working as the material, homework it sets and marks, notes, flashcards or a mind map it can leave from the lesson, and a memory of how you learn that carries between lessons. The useful comparison is whether that flow helps you understand and practise your topic, not whether another assistant can explain it.
Half an hour free. No card.
