Get openpencil with one command
Pick your system, reveal the step-by-step guide, copy the command, paste it into your terminal and press Enter. This command was taken from the project's own documentation and checked against it.
Not available for Windows yet.
openpencil doesn't publish an install command for Windows anywhere we can verify, so there's nothing for us to show you. We won't invent one. It does document one for macOS and Linux — switch to that tab.
Pastes into PowerShell and installs openpencil on your Windows machine in one step — no manual setup, no build tools. It fetches the project's own install script and runs it, which is the standard way these tools ship — worth a read if you like to know what's running.

How to set up openpencil, step by step
On Windows, open PowerShell (press Win, type PowerShell, hit Enter) and paste the command. On macOS or Linux, open Terminal — on a Mac it's in Applications ▸ Utilities, or press Cmd+Space and type Terminal — and paste the command there.
Run openpencil --help to see the available commands, and
openpencil --version to confirm the install worked. If your shell complains about
permissions, that project usually documents a corrected command on its own site.
This asks PowerShell to download a small installer script from the project, then execute it in memory. Nothing is saved to disk. The script is the project's own, but it's worth reading it first — that's why there's a note above.

On mobile
openpencil is a command-line tool, so there is no phone app for it — a phone has no shell to run it in. You'll need a desktop, or a remote shell into a machine that has one.
openpencil is developed by its own authors. This page is an independent reference; we are not affiliated with or sponsored by the project. The command shown here was reproduced from the project's public documentation — always check the project's own documentation before running anything.
