better retention with active recall quizzes vs re-reading notes

per day — only pay on the days you actually study
You have 400 pages to cover before Thursday. Your exam will come strictly from your course textbook — but every AI you try keeps giving answers from the internet, not your book. Sometimes it cites the right concept but the wrong definition. Sometimes it invents a page reference that doesn't exist. You don't need an AI that knows everything — you need one that stays inside your syllabus and lets you ask follow-up questions without losing the thread.
The specific problems
Built specifically for how students actually use AI.
Upload any PDF — your textbook chapter, lecture slides, official study guide, or past exam paper. Set a page range. Every answer LumiChats gives is drawn exclusively from those pages, with the exact page number cited. Crucially, follow-up questions work: 'explain that with an example', 'how does this connect to what you just said', or 'go deeper on point 2' — the AI carries the last two exchanges into each new question, so your study session flows like a conversation with a tutor. Works for any university, any country, any textbook.
Active recall is the most evidence-backed study technique in cognitive psychology — students who self-test retain 50% more than those who re-read. Tell LumiChats which pages to quiz you on, pick easy / medium / hard, and get a full MCQ set aligned with your exact syllabus. Not a generic internet version of the topic — questions drawn from the actual pages you uploaded. If you exit a quiz early, the partial attempt is saved and labelled in your history so your score record stays accurate.
GPT-5 for mathematical problem-solving. Claude Sonnet 4.6 for essay writing and long-form answers. Gemini for research and current affairs. DeepSeek for coding assignments. All available on one day pass, switchable mid-session. You don't need four separate subscriptions — you need one platform that holds all of them.
Most students use AI intensively for 8–12 days per month around exams and deadlines. At ₹69 / under $1 / ~€0.85 / ~£0.75 per day, that's roughly $8–$12 a month during exam season — and nothing during breaks. Compare that to $20/month for ChatGPT Plus, charged whether you're studying or not. The math is simple: if you study with AI fewer than 20 days a month, LumiChats costs less. Most students use it fewer than 15 days.
After a study session, ask LumiChats to generate revision notes from your conversation. Get a clean, structured summary of everything you just covered — headings, key points, formulas, definitions — ready to save and revisit before the exam. Share with classmates for group revision.

“I had 400 pages of Organic Chemistry I hadn't touched. Study Mode let me go chapter by chapter. I asked it to quiz me on pages 34 to 67. It stayed exactly there — every answer had a page number. Then I asked 'how does this reaction mechanism connect to what you just explained?' and it actually remembered. Not a single hallucination from outside those pages. I finished the chapter in 3 hours instead of a full day.”
