Example session

Example Quiz me session:

  1. Revisia: Question 2. Why is demand for insulin price inelastic?
  2. You: Because people really need it? (marked worth another look)
  3. Revisia: Close, but vague. In economic terms, what makes demand inelastic?
  4. You: It's a necessity with no close substitutes, so people keep buying it when the price rises.
  5. Revisia: That's it. Fewer substitutes, less elastic demand. I've made you a flashcard for it.

At the end: 1 thing worth another look · 1 flashcard made.

Elasticity is how much demand changes when the price does.

You01:40spoken

So if a small price rise cuts demand a lot, it’s elastic.

From “I don’t get it” to “go on, quiz me”

Every session, lecture and flashcard feeds one picture of what you know and what to do next.

Examples shown.

Explain it back

Teach a topic to Revisia in your own words, typed or spoken. It points out the parts you skipped and anything you got slightly wrong.

You

Working memory is basically short-term memory. It holds a few things for a few seconds.

Revisia

Nearly. You skipped what it’s made of: the central executive and the systems it controls.

Gap: central executiveGap: phonological loop

Quiz me

Exam-style questions on your topic, with a follow-up whenever an answer is vague, the way an examiner would. Answer out loud to practise for orals and vivas.

Contract law · Question 3
Revisia

What is consideration in a contract?

Youspoken

Something of value each side gives the other, like money for goods.

Revisia

Good. Can a promise to pay for something already done count?

Record a lecture

Leave Revisia open in a lecture and it turns what’s said into notes: a summary, timed key points, the topics covered and flashcards. Only the text is kept. The audio is discarded as it goes.

Questions before you start

How long is the free trial, and what's included?
7 days, with everything except voice: unlimited typed sessions, quizzes, lecture recording, flashcards and progress tracking. Voice starts when your plan does. You'll need a card to start.
What happens when the trial ends?
Your plan starts automatically: €11.99 a month for Revisia, €19.99 for Revisia Pro. We'll email you 2 days before, so it never comes as a surprise. Cancel within 7 days and you pay nothing. After that you can cancel anytime from your account.
What's the difference between Revisia and Revisia Pro?
Voice. Revisia includes 3 hours of voice a month, which is plenty if you mostly type. Revisia Pro gives you unlimited voice, for when you'd rather talk every session through and hear the answers. Everything else is the same, and you can switch plans in your account at any time.
How is Revisia different from ChatGPT?
Revisia asks the questions. It quizzes you like an exam, has you explain topics back, works from your own notes and lectures, and keeps track of what you still need to revise, with a summary and flashcards after every session. A general chatbot answers whatever you ask, which feels productive but rarely shows you what you'd get wrong on the day.
Can I talk to it instead of typing?
Yes, once your plan starts: 3 hours a month on Revisia, unlimited on Revisia Pro. Tap the mic in any session and say your answer. Revisia sends it when you stop talking and reads its reply aloud, and you can tap Stop to jump in. Your voice is turned into text as you talk, and the audio isn't kept.
Is using Revisia cheating?
Revisia is designed to make you do the thinking. In explain-it-back mode you teach and it checks; in quizzes it asks and you answer. If your school or university has rules about AI for graded work, follow them.
Will it know what my course covers?
Revisia covers every subject. Upload your notes, slides or syllabus, or record your lectures, and it matches its explanations and questions to your course.
Can I trust its answers?
Like any AI, Revisia can get things wrong. Working from your own notes helps keep it on track, and it's worth checking anything important against your course materials.
Does it work on my phone?
Yes. Revisia runs in the browser on your phone, tablet or laptop, so there's nothing to install. Android and iOS apps are on the way. For voice sessions somewhere noisy, headphones help.
What happens to my notes and recordings?
Only you can see them. We never use your notes or your conversations to train AI, and we never sell or share them. When you talk or record a lecture, speech is turned into text as it goes and the audio isn't kept. You can delete any file or session whenever you like, and deleting your account removes your notes, sessions and progress.
Who is Revisia for? Is there an age limit?
Students revising for exams, at university or in their last years of school, wherever they study. You need to be 13 or over to sign up.
