A tool that builds an app to turn photos into brushstroke paintings

A case of using Claude to build an app that shows a photo being painted with brushstrokes.

How it works

  1. Simon Willison asked Claude Opus 5.5 High for an app that opens a photo and repaints it with brushstrokes in a few seconds.
  2. The published Quick Study uses canvas and simulated brushstrokes, with Sobel edge detection to find image boundaries.

Results

The author shared an oil-painting-like rendering of a heron photo and a link to the tool.

Notes

The author says it uses no external libraries other than Google Fonts. Quality across different photos and measured processing times were not published.

Example prompt · Claude

Please implement an app in [target browser] that recreates [user-selected photo] as a brushstroke painting. First check image input and canvas support, and propose local processing without uploading photos to a server. After file selection, read the original into canvas and use Sobel edge detection to guide brush direction or detail. Show brushstrokes accumulating rather than displaying the finished picture all at once. Implement downscaling rules for large originals and input error handling. Provide runnable code, instructions for opening it, and verification results for each test photo. Use [landscape photo] and [portrait photo] to check the original proportions, edge rendering, and responsiveness while processing, and report only times actually measured. Do not guarantee identical speed or image quality on every device.
