We are a specialized studio that converts photographs into ultra-light tracing outlines that completely disappear under watercolor, graphite, oil, or acrylic.
Fundamentally different from tools like Canva or Fotor that create finished digital sketch effects, Sketchso creates a preparatory guide for traditional physical art. It's a modern replacement for the lightbox—solving the physical limitation of tracing through thick watercolor paper.
Ultra-light 8–15% opacity outlines vanish under traditional media.
Print direct. Replaces bulky $50–$200+ lightboxes.
Privacy by design. We never store or use images to train models.
Sketchso is built to make the beginning of a piece feel clearer: better structure, less guesswork, and a smoother path into your real drawing or painting process.
Upload a portrait, pet photo, landscape, or any composition you want to translate into a cleaner starting point.

Built for the moment between reference and real artwork
Invisible tracing outlines are light reference guides created from photos that you can print and use as a base for your artwork. They're designed to be so light (8-15% opacity) that they completely disappear under watercolor, pencil, ink, colored pencil, markers, or any art medium, leaving only your original artwork visible.
To trace a photo for art, convert your photo into a light outline using a digital tool, print it on paper, then draw or paint directly over the outline. The outline will disappear under your pencil, ink, watercolor, or any medium, creating authentic artwork.
Invisible tracing outlines work perfectly with colored pencils, graphite pencils, watercolor, ink, markers, gouache, and acrylic. The light outlines disappear under any opaque or semi-opaque medium.

| Watercolor | Excellent | Landscapes, portraits, loose paintings |
| Ink & Pen | Excellent | Line art, illustrations, comics |
| Markers | Very Good | Illustrations, graphic art, bold colors |
