AI Explainer Video
An explainer video for any topic you study.
Pick one topic from your course and StudyPDF makes a narrated, animated video that teaches it. It opens with the question and your concepts, then explains one concept after another with diagrams, plots, worked examples and formulas, built from the pages of your documents.

How it works.
- 1
Pick a topic
Choose one topic from your uploaded course, or type a topic when you have no documents.
- 2
Choose the length
Short, medium, long or auto. Long adds the typical mistakes for each concept.
- 3
Watch, then test yourself
Jump between chapters, then make a quiz or flashcards for the same topic.
One concept at a time, shown, not just told.
The video opens with the question the topic answers and your concepts. Then it takes one concept after another and builds it up on screen while the narration explains it.



Frames from a demo video on a typed machine learning topic, made without documents. A video made from your documents follows your pages and names the page each part comes from.
As long as you have time for.
A lesson, not a marketing clip.
- No avatar and no presenter talking into a camera.
- No stock footage. Every picture is drawn for the concept.
- Plays in the app with chapters, so you can jump to the concept you missed.
- Your progress is kept, so you can stop and pick up later.
- In your language: Danish, Dutch, English, French, German, Italian, Norwegian, Polish, Portuguese or Spanish.
Watching is the start. Testing makes it stick.
A clear video feels like learning, but recall is what lasts. When the video ends, make a quiz or flashcards for the same topic and find out what you actually remember.

Questions, answered.
How long is a video?
You pick the length. Short is about 5 minutes, medium about 8 and long about 13, with the typical mistakes for each concept added. Auto sizes the video to the topic, which comes to about 8 minutes for a topic with 7 concepts.
What does the video cover?
It opens with the question the topic answers and its concepts. Then it explains one concept after another with a diagram, a plot, a worked example or a formula, whatever fits the concept, and the narration walks you through it step by step.
Do I need to upload documents?
No. You can type a topic and get a video without documents. When you make it from your own documents, the video follows your pages and shows which page each part comes from, so it teaches what your course covers.
Is it an avatar video?
No. There is no avatar, no presenter and no stock footage. The video is narrated and animated: the diagrams, plots and formulas build up while the voice explains them.
Can I download the video?
Not for now. The video plays in the app, where you can jump between chapters and pick up where you stopped.
Is it free?
You can try one topic for free. Pro and Ultra include a number of videos every month.
