Turn Any Photo Into Clean, Customizable Line Art
ProTrace is an AI photo-to-line-art tool built for artists. Preserve important structure, control the amount of detail, adjust line weight and fidelity, and create a clean outline for your creative workflow.
From reference to workable line art, with controls that keep the artist in charge.
A visible difference
Not another edge-detection filter.
Traditional outline converters detect contrast boundaries and reproduce them as edges, often creating noise, broken lines, and meaningless texture. ProTrace is designed to interpret the subject’s structure and generate purposeful linework that artists can direct and refine.

FAQ
The short version.
What is the difference between an outline filter and AI-generated line art?
An outline filter detects contrast boundaries and reproduces them as edges. ProTrace is designed to interpret meaningful structure, suppress less-useful photographic texture, and create linework an artist can direct and refine.
Can artists control the amount of detail?
Yes. ProTrace includes controls for primary line weight, facial detail, organic detail, secondary detail, fidelity, and optional shading-zone markings.
Can ProTrace create tattoo stencil linework?
ProTrace can create linework from a reference image for further artistic preparation. Generated output is interpretive and should be reviewed before use.
