Pixel-perfect by design.
Strokes land exactly where you draw. No calibration, no math. The iPad sees the literal pixels from the Mac — so a pixel on iPad is a pixel on Mac. Alignment is mathematical, not heuristic.
Beam your strokes to any screen.
The missing layer between a hand and every display in the room. Draw on a tablet — any tablet — and watch every mark appear on a connected screen, in real time, with the latency of ink on paper.

Apple Pencil on iPad, Wacom on Android, S Pen on Samsung — into Mac, Windows, a projector, or three at once. The Lipi protocol doesn't care what hardware sits on either end.
Below the threshold where ink feels like a network request. WebRTC over LAN or USB. Sub-40ms over USB. No accounts, no cloud, no setup. Works on a plane, on a stage, in a classroom.
Sixty seconds. Two URLs. The first stroke before the kettle boils.
Run Lipi on your Mac. Click START CAPTURE — pick a window, a tab, or your full screen.
Open the same Lipi URL on your iPad. The Mac screen mirrors live, pixel-perfect.
Apple Pencil meets glass. Every mark beams to the Mac in under 80 milliseconds.
Point OBS, Loom, or QuickTime at the Mac display. Strokes are baked into the recording.
Run it yourself for free, or let us run it for you across any network — no setup.
Teaching should feel like thinking out loud. The moment a teacher picks up a stylus, every mark should appear — instantly, beautifully — on every screen in the room, on every device watching remotely, and in every recording ever made of that session.
