Turn photos into pencil, ink, or storyboard sketches with AI. Preserve pose, likeness cues, object shape, and lighting for usable drafts.
Use a reference image when the tool depends on an existing photo, sketch, or artwork. Uploaded references are saved and sent to supported image models as inline visual context; unsupported models fall back to prompt-guided generation.
Upload or describe a source photo, then decide what the sketch must preserve. Strong results begin with a clear subject and a clear drawing job.
Choose the model after the creative brief is clear.
