Frequently Asked Questions
Everything you might want to know about Lumio before signing up — how it works, what it costs, and how we keep your data safe.
Is Lumio really free?
Yes. Every student account gets 6 free AI sessions and unlimited access to non-AI tools like flashcards, goals, calendar, resources, and the opportunity finder — forever, no credit card required.
Who is Lumio for?
Lumio is built for students learning at home — whether you're supplementing what you get at school, homeschooling, prepping for exams, or teaching yourself something new. Everything is designed around what a single student needs to learn effectively.
What grade levels does Lumio support?
Lumio works best for grades 5-12 and early college. The AI adjusts its explanations to match how much you already know so younger students aren't overwhelmed and older students aren't talked down to.
Which subjects does the AI tutor cover?
Math (pre-algebra through calculus and statistics), the sciences (biology, chemistry, physics, earth science), English literature and composition, world and US history, foreign languages (Spanish, French, Mandarin, and more), and computer science. It also helps with study skills, test prep, and college essays.
Will the AI just give me the answers?
No. The tutor is built around a Socratic method — it asks guiding questions, offers hints, and walks through worked examples. It's designed to help you actually learn, not to do the homework for you.
How does the flashcard system work?
You build decks (or generate them from notes), then study using spaced repetition. Cards you get wrong come back sooner; cards you know cold come back later. It's the fastest scientifically-backed way to memorize material.
How does Lumio protect my data?
Your data is encrypted and stored with strict per-user access controls, so only you can see your own work. We never sell personal data. See our Privacy Policy for the full details.
What languages does Lumio support?
The interface and AI conversations work in English, Spanish, French, Chinese, and Arabic.
How is Lumio different from ChatGPT?
ChatGPT is a general-purpose assistant. Lumio is purpose-built for learning: it's Socratic by default, subject-aware, and paired with flashcards, a study planner, a goal tracker, a resource library, and a scholarship/opportunity finder — the full toolkit a student actually uses, not just a chat window.
What does Pro get me?
Unlimited AI tutor, writing coach, and study tools — plus no ads and faster AI responses. It's $4.99/month, cancel anytime.
