What Lumi is
The basics, for anyone who arrived here from a search result.
Lumi is a voice-first AI tutor for UK students. You talk to it out loud or by typing, and it teaches on a live board while it talks back — writing out the working, drawing diagrams, plotting graphs — so you watch the explanation appear rather than reading a finished answer. You can interrupt it, ask it to go back, or ask for the same idea a completely different way. It covers GCSE, A-Level and university, with reviewed teaching packs for eight AQA and Edexcel courses and A-Level as its main focus.
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.
No, and it is not trying to replace one. Those are content libraries: notes, worked solutions, quizzes and past papers to work through. Lumi is a tutor you hold a conversation with, for the point where you have read the notes and they are not going in. Most students use both.
Lumi is built by Rayhan Khilji and Adan Khan. It was made because a class of thirty cannot stop for one person, and the usual fix for that is a private tutor at £30 to £60 an hour.
Cost
What it costs, what the free plan really is, and the one discount there is.
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.
Plus is £28 a month billed monthly, or £175 a year billed once — £161 less over the year. Both include 120 minutes of tutoring a week, resetting every Monday.
One, and it is real rather than a countdown. Share your referral link and a friend gets 25% off their first payment — monthly or yearly. The moment they pay, a free month of Plus is credited to your account.
120 minutes of tutoring a week — over 8 hours a month — with lessons of up to 120 minutes. Homework gets set and marked with a real mark, "check my working" reads your handwritten steps and names the line that went wrong, and Lumi remembers how you learn between lessons and revisits topics before you forget them.
Considerably. A private tutor in the UK typically costs £30 to £60 an hour. Plus on the yearly plan works out at roughly £2 an hour of tutoring — and that is for every subject, not one.
Any time, and you keep access until the end of the period you have already paid for.
Subjects and exams
Whether it covers what you are actually sitting.
The subject pages go into detail on Maths & Further Maths, Physics & Chemistry, Biology & Psychology, Economics & History. It is not limited to those: pick a named course or just ask it anything, including things that are not on a syllabus at all.
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.
Yes. It covers GCSE, A-Level and university. The reviewed packs span both — GCSE maths and the GCSE sciences sit alongside A-level maths and economics — and the tutor underneath does not stop at any syllabus.
Yes, and mid-lesson rather than only at the start. Attach a past paper PDF, a photo of the question or your own working, a text file or a YouTube link, and Lumi reads it — or watches it — and teaches from what is actually confusing you.
Rules and trust
The questions parents and teachers ask.
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'.
Yes, and it says so when it does not know rather than inventing an answer — but you should still treat it the way you would treat a very well-read tutor rather than an oracle. Check anything that decides a mark against your specification, your textbook or your teacher. The advantage of being drawn out on a board is that a wrong step is usually visible rather than buried in a paragraph.
It is built for GCSE upwards. Younger students can use it with a parent involved, but the explanations assume the vocabulary and pace of secondary study.
No. It replaces the hour after a lesson where you sit looking at a page you did not follow, which is the hour most students currently spend alone.
Using it
Practical questions about actually sitting down with it.
No. Lumi runs in a browser, on a laptop or a phone. There is nothing to download.
No. Voice is how most people use it — Lumi talks back and the board draws in step with the explanation — but everything works typed if you are somewhere you cannot talk.
You say what you are stuck on — or attach the paper, photo or YouTube link it lives in. Lumi explains while drawing on the board: the curve, the force diagram, the working written line by line. You interrupt, point at part of it, ask for it a different way. It sets homework if you want it and marks it with a real mark, a quiz on the board checks what actually landed, and the lesson can be left behind as notes, flashcards or a mind map before you go.
Create an account and start a lesson. The free plan needs an email address and nothing else, so you can find out whether it works for you before deciding anything.
