Why quiz yourself on a video?
Watching a lesson feels like learning, but recognising an explanation is not the same as being able to produce it. Answering questions from memory, known as retrieval practice, is one of the most reliable findings in learning research. In a 2006 study by Roediger and Karpicke, students who were tested on a passage remembered more of it a week later than students who spent the same time studying it again. A quiz made from the lesson you just watched turns that finding into a habit: answer first, then read the explanation. The questions you get wrong are the useful part, because they show you which idea from the video has not stuck yet. For the whole method, read our guide on how to study from YouTube videos.
What does a good question from a video look like?
A useful question asks you to use an idea, not to repeat a sentence. Look at the questions above: one asks you to apply the rule a network uses to pick its answer, one asks you to predict how a detector should change, and one asks you to calculate a number the lesson never states outright. Each answer comes with a short explanation, so a wrong answer still teaches you something. Questions are written from the transcript, which means an equation or diagram that only appears on screen may not be covered. Videos with clear narration make the strongest quizzes.
A quiz after the video, or questions during it?
Pausly gives you two ways to practise with the same lesson. A quiz is a set of 1 to 20 multiple-choice questions you take when you are ready, at easy, medium or hard difficulty, with an explanation for each answer. Focus Mode works while you watch: it pauses the video at moments chosen from the lesson, asks a multiple-choice, fill-in-the-blank or open-ended question, then carries on. Use Focus Mode the first time through a lesson, when staying attentive matters most, and take a quiz afterwards or the next day to check what you still remember.
Before you make your first quiz
Which YouTube videos work?
Public videos with captions or an available transcript. Pausly reads what is said, not what is shown, so silent demonstrations and equations that only appear on screen may be missed. Private, unavailable or caption-free videos may not work.
How many questions can I make?
Up to 20 per quiz. You choose the number of questions and one or more difficulty levels before anything is created.
Can the questions be in another language?
Yes. You choose the language the quiz is written in, and it can differ from the language of the video.
Is it free?
You can start for free. Creating a quiz uses part of your weekly usage, and Pro gives you more.
Does Pausly pause the video for every question?
Only in Focus Mode, which you turn on yourself. Without it, the video plays normally and you take the quiz whenever you choose.
Is every question correct?
Most are, but AI can misread a transcript. If a question or its explanation looks wrong, check it against the video; the explanation tells you what the answer is based on.
