Digital Illustration & Concept Art

Illustrators and concept artists can keep mood boards, anatomical references, color studies, and style guides pinned around their drawing software. This allows for constant visual feedback, ensuring accuracy in proportions, lighting, and palette without breaking concentration to search for files, dramatically speeding up the sketching and rendering process.

UI/UX & Web Design

Having immediate access to these references ensures consistency and inspiration are always visible, streamlining the design process from prototype to pixel-perfect final asset.

3D Modeling & Animation

3D artists and animators can reference orthographic views, texture maps, motion studies, and video tutorials in always-on-top windows over Blender, Maya, or ZBrush. This is invaluable for matching proportions, studying movement frame-by-frame with GIF controls, and applying textures correctly, all while keeping the main viewport clear for work.

Motion Graphics & Video Editing

Motion designers and editors can keep storyboards, style frames, asset lists, and video references visible while working in After Effects or Premiere Pro.
