For learners
Your material. Your tutor.
Upload the notes, slides or PDF you are actually studying from. Zelvi turns them into practice you can do, and answers your questions from the page they came from — not from the internet.
Free plan: 15 tutor messages, 5 flashcard sets and 3 uploads a day. Voice is on the paid plan.

Everything is built from your own source.
- Ava, your tutorAsk in text or out loud, and have her reply in your own language. Every answer cites the page it came from, and she declines rather than inventing one.
- QuizzesGenerated from your own material, not from a generic question bank.
- FlashcardsTurn a lecture, a PDF or a set of notes into cards you can drill.
- Mind mapsSee how the ideas in a document actually connect.
- Study guidesA structured summary built from the source, with the source kept.
- Exam drillPractise under time, then review only what you got wrong.
- NotesKeep your own notes beside the material they came from.
- Voice tutoringTalk to Ava, interrupt her mid-sentence, and be understood.
Not slides. Not a video.
Things you can take apart.
Studying for a course?
If your school runs Zelvi, your tutor knows your syllabus.
Ask your instructor. When a course is published, Ava answers from that course’s own material and can pass a question you are stuck on to the person who teaches it.
