できることSketch naturally
Full Apple Pencil drawing with layers, eraser, undo/redo, zoom and pan — it feels like drawing on paper.
AI manga transform
Turn rough sketches into clean manga-style art while keeping your composition. Your idea, polished ink.
Paint to refine
Not happy with a result? Brush over any part of an AI image to repaint just that spot, or regenerate the whole panel until it fits your story.
Speech bubbles
Add editable manga-style speech bubbles, write your dialogue, and arrange them freely on the page.
