What is a Video Overview?
GoodOff’s Video Overview is a short vertical video generated from your study material. The AI writes a script, illustrates each scene with generated images, and records narration. Each video uses structured scene types — hooks, concept explanations, examples, big-fact callouts, recaps, and interactive quiz questions — so the format teaches, not just summarizes. You can optionally focus on a specific topic within your source. Videos play in a full-screen vertical player with a story-style progress bar, captions toggle, and mute control.

Every scene gets an AI-generated illustration and text-to-speech narration, synced to the content.
Built-in quizzes
Quiz scenes appear inside the video. Pick an answer, get instant feedback, then continue watching.
Topic focus

The science behind Video Overview
Microlearning
Learning in short, focused bursts rather than long sessions. A short video overview is a microlearning tool — quick to consume, easy to repeat.
Multimedia learning
Combining visual (illustrations), auditory (narration), and interactive (quizzes) information. Video overviews engage multiple senses and retrieval modes.
Testing effect
Answering questions during learning strengthens memory more than passive review. Quiz scenes inside the video trigger active recall mid-watch.
