Write and revise branching fiction from your terminal.

1667 is a full-screen terminal app for fiction writing. Write story parts, keep alternative takes, and select the story line that you want to read. Connect a model when you want generated prose, or write every take yourself.

This repository contains the terminal user interface (TUI) and its backend.

On macOS or Linux, use the Shell Installer:

curl -fsSL https://1667.ai/install.sh | sh

On Windows x64, use the PowerShell Installer:

powershell -ExecutionPolicy Bypass -c "irm https://1667.ai/install.ps1 | iex"

After installation, open a new PowerShell window. Start 1667 with this command:

1667.exe

Include .exe when you start 1667. The command 1667 does not start the app because PowerShell treats it as a number.
