Create monochrome line art and compare faces, hair, hands, clothing, panels, and text with the source.
Try this tool

Preserve structure: Keep the source composition, identity, anatomy, panels, and important interior contours. Remove color and soft shading: Strip color fills, gradients, and soft painted shading while retaining meaningful drawing lines. Keep useful detail: Preserve eyes, hair strands, clothing seams, hatching, and readable lettering when they belong to the drawing.

Line extraction is not vector tracing: Painterly edges may simplify into broken or approximate lines.

USER FEEDBACK
How creators use this tool before moving into the next manga editing step.
It gives me a usable monochrome base for recoloring when the source has clear anime-style contours.
Faces and hair usually stay readable, but I still inspect fingers, eyelashes, and broken thin strokes before reuse.
Painterly textures can turn into extra marks, so I treat the result as raster line art that may need a cleanup pass.
