The Project
Most drawing tools ask for an account before they ask what you want to draw. Penci.ly inverts that: the canvas is the landing page, and persistence is something you opt into once the sketch is worth keeping.
Development
The rendering layer is a hand-written canvas pipeline rather than an SVG scene graph, which keeps stroke latency low on mid-range devices. Documents sync through Convex once a sketch is claimed.
