Write With Character
29 distinct pens and brushes, including fountain pen, calligraphy, fude brush, technical pen, watercolor wash, charcoal and mechanical pencil (2B/4B/6B), each with its own texture and stroke response. With a compatible stylus, pressure and tilt shape supported strokes, while palm rejection helps prevent stray marks. Whole-stroke, pixel, and precision erasers handle corrections. Use the lasso to move, scale, copy, or delete strokes, plus eight shape tools and a laser pointer for presentations.

100 Distinct Notebook Styles
Each Studio Style has its own cover, paper structure, color palette, dividers, stamps or stickers, and toolbar accent. The collection includes minimal, linen, Japanese grid, academic, engineering, music, meeting, research, planner, travel, wellness, recipe, creative, and dark-paper systems, so one note taking app can be your lecture notebook, digital planner or daily journal. Browse and preview all 100 styles before choosing one.
