Show HN: I built an app that turns any image into 5-step pencil drawing practice

Hey all!

My girlfriend is really good at drawing and wants to become an illustrator for children's books, so she's practicing drawing various animals.

We were at a cafe and she got stuck staring at a blank page trying to draw a fox using a reference photo. So I generated some pencil sketches from the reference image with ChatGPT. Seeing the drawing broken down step by step made it easier to start for her.

The next day she asked me to generate sketches for 10 more photos, so I decided to polish my prompts and wrap the workflow in a self-service app for her.

The app allows you to upload any image and it generates 5 pencil sketches from the uploaded image, from basic shapes to a fully detailed pencil sketch.
