Product Overview
What is copainter?
copainter is a web-based creative tool built for illustration, manga, and anime workflows. It helps artists move from rough sketches to refined lineart, base colors, shading, finished coloring, and higher-resolution outputs. Rather than replacing the entire drawing process, copainter focuses on accelerating repetitive production stages while keeping the creator's source artwork and editing decisions at the center. Its browser-based workflow and layered export options make it practical for both independent artists and professional production teams.
