How it works
From your notes to spoken mastery in minutes.
Scan your notes
Photograph pages or upload a PDF. The app turns them into structured study knowledge, split into chapters and organized by subject.
Talk it through
Start a voice session with your tutor. It follows your material chapter by chapter, questions you and corrects you out loud.
Review until it sticks
Quizzes built from your notes come back on a spaced schedule, so weak spots resurface before you forget them.
Why a voice tutor, not another chatbot
An AI voice tutor is a tutor you talk to. It listens, answers out loud, asks you questions and corrects you in real time, the way a study partner would.
A real conversation, not text read aloud
Sessions run as live spoken dialogue. You can interrupt, ask for an example or say you did not understand, and the tutor adapts on the spot instead of reading a prepared answer.
A tutor that learned your course
Generic assistants answer from the whole internet. Replio's tutor works from the chapters you uploaded, so it uses your teacher's vocabulary, your examples and your exam scope.
Explaining out loud shows what you know
Rereading feels productive but hides the gaps. Explaining a chapter in your own words to someone who asks follow-up questions finds them fast, and the quizzes bring the weak spots back later.
What is inside
An app built on the same engine that trains professional teams.
A tutor that knows your course
One tutor character you create once, with a name and a voice you choose. It teaches every subject from your own notes.
Real voice conversations
Explaining out loud is one of the most effective ways to learn. Sessions are natural, real-time dialogue and you can interrupt at any moment.
A course plan from your chapters
The app reads your material's own structure and turns it into an ordered plan. One session covers one chapter.
Quizzes with spaced repetition
A question bank generated chapter by chapter from your notes. Questions you miss come back sooner; solid ones space out.
One space per subject
Every subject keeps its own study space, from the first photo to exam day.
A companion that grows with you
Pick a study companion and earn accessories for it by keeping your study streak alive.
Free to start: one subject, quizzes from your own material and a trial of tutor minutes. Subscriptions unlock more tutor minutes and subjects. Android, for students aged 16 and over.
The app speaks 10 languages and runs on the same European platform that companies use to train their teams.
How Replio compares to other AI voice tutor apps
Notilo, iTutor, Knowt, Khanmigo and ChatGPT Voice all let students talk to an AI. We put them side by side with Replio on what matters: your own notes, a chapter plan, quizzes, languages, free tiers and where your data is processed.
