PencilKit

Draw & Annotate on Any Webpage

PencilKit brings a drawing canvas directly onto any webpage. Whether you are annotating a design mockup, sketching a quick idea, or marking up a document — PencilKit feels completely natural.

Designed with calm and clarity in mind. No bloat, no noise — just a clean canvas wherever you need one.

Canvas Overlay

A transparent drawing layer floats over any webpage, letting you sketch freely without affecting the underlying content.

Pen, Marker & Eraser Tools

Switch between a precision pen, a chunky marker, and an eraser — all accessible via the floating toolbar.

Color & Opacity Control

Pick any color and adjust stroke opacity for subtle highlights or bold annotations.

Export to PNG

Capture the annotated view as a clean PNG — composited over the page at its current scroll position.
