01

Actually local

Your PC and iPad talk directly. There is no account, cloud service, or internet connection involved in a drawing session.

02

Your Pencil still feels like one

Pressure and tilt reach your Windows drawing app, so you can work with the tools and brushes you already know.

03

Nothing extra to carry

Open Safari on the iPad you already own and leave the separate graphics tablet—and another subscription—at home.

Three steps

Nothing to install on the iPad.

Start NFiDB on Windows, connect with Safari, then draw in the app you already use.

Technical details

Under the hood.

The short version: your Windows PC does the work and your iPad connects directly to it.

01

Local video

NFiDB detects working hardware codecs, verifies what the browser can present, and sends video over a direct WebRTC connection. No cloud relay is involved.

02

Native pen input

Safari Pointer Events carry pressure and tilt back to Windows as native PT_PEN input. Predicted events remain visual-only.

03

Files and diagnostics

Explicit file queues move data in either direction. Live stats cover latency, bandwidth, input integrity, and transfer results without sending data elsewhere.
