How is an AI tutor different from a chatbot?
The difference is where the answer comes from. Ask a general chatbot about a topic and the reply is an average of everything it read on the internet, not the part your lecturer emphasised. Solvie reads the text of the file you chose and speaks from that. If the definition on your slide is the one the exam will use, that is the definition you hear. The limit has a useful side effect: when your file does not answer a question, Solvie says so instead of filling the gap. Knowing what you do not know is the thing a student needs most, and a tool that dresses a guess as an answer destroys exactly that. Solvie calls a guess a guess.
Can you interrupt it?
Yes, and it matters more than it sounds. With a teacher in front of you, you stop them at the point you lost the thread. With a recording you cannot, which is why listening to a recording is revision rather than tuition. Solvie needs no wake word to be interrupted: an ordinary sentence does it, so saying "I did not follow that part" stops it. It waits until you actually speak, it does not treat a cough as your turn, and it does not jump in while you are thinking mid sentence. On Ultra the lesson runs live and can be broken into this way; on Premium+ it works push to talk, so you open the turn yourself. It understands Turkish, English, Spanish, German and Italian from how you speak.
Who picks what the lesson covers?
You can, but if you do not, Solvie does not start from a blank page. It looks at two things: the topics you keep missing in quizzes, and the task you keep pushing back in your study plan. Both come from what you did rather than from a questionnaire. In practice this means your least favourite topic turns up, which is the point, because you are already studying the one you like. What gets covered feeds back into weak topic tracking, so a spoken lesson does not sit on its own island.
Why does explaining out loud work?
When you try to say a topic in your own words, the gaps you did not notice while reading become obvious at once. That is the idea behind the Feynman Technique, and the Socratic method does the same thing from the other end by asking instead of answering. Solvie uses both, so it does not only talk: it makes you talk. Where you stumble while explaining something to it is the most honest measure of where you actually are. Teaching through software is not a new idea; intelligent tutoring systems are a forty year old field. What is new is that the lesson can come out of your own file.
Is what I say recorded?
Not unless you turn it on. Solvie chat history is off by default. If you switch it on, you set how long it is kept: 30, 90 or 365 days. You delete it whenever you like, and deleting is immediate rather than a request. Because speech recognition has a real error rate, you can correct a line the transcript got wrong; a sentence stored incorrectly defeats the point of storing it at all.
How many minutes is enough?
The free plan has no voice tuition; it has quizzes, flashcards, audio recaps and duels. Premium+ brings 90 minutes a month of push to talk coaching, roughly 20 minutes a week, which covers one topic spoken through once a week. Ultra brings 300 minutes of live tuition, about a lesson period every weekday. Rather than guessing which one fits, run a month on Premium+ and see whether the minutes run out before the month does. Current figures are on the pricing page. Bloom's two sigma study gets quoted whenever tuition comes up because it measured one to one teaching against a class; the claim here is not that one, since what it measured was a human teacher.
Does Solvie set you homework?
Yes, and the homework arrives as a continuation of the conversation. Solvie opens a private classroom for you and sends work there from the places you stumbled during the lesson, so the session ends with a concrete next thing to do rather than a good feeling. The value is precise: a spoken lesson produces understanding but not retention, and solving produces retention. Homework closes exactly that gap. What it covers is decided by where you struggled in that lesson rather than by a generic schedule. Once you work through it the result feeds weak topic tracking, so lesson, homework and tracking stay on one chain instead of sitting on separate islands.

Can an AI tutor really teach a lesson?
Solvie speaks from the text of the PDF you picked, asks you questions and gets you explaining. The limit is that it will not teach something your file does not contain; it tells you the file does not answer that.
Which plans include voice tuition?
Not the free plan. Premium+ includes 90 minutes a month of push to talk coaching and Ultra 300 minutes of live tuition. Interrupting mid sentence is an Ultra feature.
Which languages does it understand?
It understands Turkish, English, Spanish, German and Italian from how you speak.
Is my conversation with Solvie recorded?
Not unless you turn it on. If you do, you pick 30, 90 or 365 days, delete it whenever you like, and correct any line the transcript got wrong.
Do I choose the topic?
You can. If you do not, Solvie picks it from the topics you keep missing in quizzes and the task you keep postponing in your study plan.
