Make a video in this style
Short answer: The notebook style draws in pen on ruled paper, with the arrows and margin notes of someone working a problem out. It suits worked examples, maths and study material, because it looks like thinking in progress rather than a finished, polished answer.
Every scene of your video is drawn in the Notebook style, so the whole thing feels like one hand from start to finish.
Give explain.ink a topic, your own script, or a document. It writes the story, draws it in the Notebook look, and records the narration. You get a finished MP4 to download, no watermark.
