Skisa doesn't filter your photo, it draws it. Pick a real instrument (fineliner, charcoal, silverpoint, quill) and a real paper (kraft, toned grey, a black ground drawn in white chalk), and the drawing comes out the way that pairing would in your hand — ink piling where strokes cross, paper tooth biting the light ones. Shade with real printmaking techniques, export a transparent PNG for tracing or coloring pages. Free is real; Premium is one-time. Fully on-device.

Could you build this?

Partial Standard image-to-sketch filters are easy, but accurately simulating physical drawing physics—stroke pressure, instrument overlap, paper tooth, and stroke order—requires custom non-photorealistic rendering (NPR) algorithms or fine-tuned diffusion models.

What it would actually take: A realistic physical-rendering pipeline requires stroke extraction via vectorization (e.g., using contour detection and path simplification) followed by a physical simulation engine (WebGL, Metal, or custom C++ shaders) modeling pigment deposition, ink flow, and paper grain heightmaps. Alternatively, it requires fine-tuning a custom ControlNet or LoRA on paired real-media stroke datasets with dedicated latent-space conditioning for paper-medium interactions.
