About SketchPulse

SketchPulse is a 100% local Midnight Sketch Studio powered by a bundled TensorFlow.js Convolutional Neural Network trained on 345 sketch classes. No drawings are ever sent to an external server.

Every stroke is normalized to a 28×28 grayscale tensor and classified in real time inside your browser. Fast guesses and consecutive streaks earn bonus points!

Completed sketches are saved locally in open .ndjson format so you can inspect or export your studio vault anytime.
