Drawing Detective processes everything locally in your browser. No PDF data is ever transmitted to any server. The only network requests are loading the page itself and the PDF.js library from a CDN.
Simply open index.html in any modern browser, or use a local server:
# Python
python -m http.server 8080
# Node.js
npx serve .A standalone Windows .exe is also available (built with PyInstaller). It starts a local HTTP server and opens your default browser. See DrawingDetective.py and DrawingDetective.spec for build details.
Made with ☕ and curiosity.
