Stencil AI is a browser-based tool for turning existing photo references into cleaner tattoo stencil drafts. Upload a photo, sketch, screenshot, or flash reference, and Stencil AI generates simplified line art that is easier to review and refine for stencil prep. A general AI image generator can be useful for exploring an original tattoo concept; Stencil AI is built for the next step: turning a chosen reference into a workable stencil base. Tattoo artists can use it to speed up client-reference cleanup; apprentices can use it as a starting point while learning stencil preparation; and hobby users can turn inspiration images into clearer references before discussing a tattoo with an artist. New accounts receive welcome credits to try the workflow.
