Grounded in your material
The prompts and feedback stay tied to the notes, lectures, and sources your course actually uses.
The teach-it-back study appDon’t just reread it.Teach it until it clicks.
Upload your study material, explain it in your own words, and let Zelmi show you exactly where your understanding breaks down — before the exam does.

How it works
From “I’ve seen this” to “I can explain this.”
Zelmi turns passive study material into a short loop of explanation, feedback, and focused practice.
- Bring the source
Add what you’re studying
Upload a PDF, notes, a photo, or a lecture. Zelmi finds the concepts worth understanding — without replacing your course material.
Your material, organized
- Explain it
Teach it in your own words
Speak or type as if you’re teaching a curious student. Zelmi listens, notices vague reasoning, and asks the follow-up that matters.
Active recall, out loud
- Know what to fix
Close the exact gaps
See what you covered, what you missed, and how clear your explanation was. Then practice the weak concepts instead of restarting everything.

Feedback you can act on
Leave every session knowing what to do next.
Zelmi separates what you covered from what still needs work, so one fuzzy idea doesn’t hide inside a page of notes you already know.
- Coverage
- Did you include the key ideas?
- Clarity
- Could someone follow your reasoning?
- Accuracy
- Was the explanation correct?

Less busywork. More signal.
A study partner built for understanding.
Speak naturally — or type
Explain it the way you would to a friend. Zelmi keeps the conversation moving without forcing a script.
Practice follows the gaps
Turn weak concepts into focused flashcards, quizzes, notes, and written tests instead of generic busywork.
Questions, answered
Before you teach it back.
The short version: bring your own material, explain it your way, and use the feedback to study smarter.
What can I study with Zelmi?
Bring lecture PDFs, typed or handwritten notes, whiteboard photos, slides, textbook chapters, voice memos, or YouTube lectures. Zelmi builds the session around the material you provide.
How is this different from flashcards?
Flashcards can test whether you recognize an answer. Zelmi asks you to build the explanation yourself, then follows the weak parts of your reasoning. You can still generate flashcards and quizzes afterward — now they target the gaps you actually found.
Do I have to study out loud?
No. You can speak or type every explanation. Voice makes the experience feel like teaching a real person, but written teach-back gives you the same structured feedback.
Is Zelmi only for science subjects?
No. The method works anywhere you need to explain ideas and connect them clearly — from biology and medicine to law, economics, history, and computer science.
