Terminal-based novel-writing tool that generates and branches AI paragraph suggestions.
1667 at a glance
1667 is a terminal-based novel-writing tool that asks an AI model for the next paragraph of your story and keeps every generated version in a navigable tree, for novelists, fiction writers, and other authors who write locally.
Good for
- Writers who want to generate multiple AI-written continuations of a paragraph and compare them without losing any earlier version
- Writers who prefer a terminal interface with keyboard shortcuts over a graphical writing app
- Writers who want their story files kept only on their own computer, with no account, analytics, or telemetry
Questions people ask
How does 1667 generate the next part of my story?
You open the composer, type what happens next, and press Enter; 1667 asks an AI model to write the next paragraph and then waits for you to continue, revise, or retry.
If I ask for another version of a paragraph, do I lose the old one?
No, every take is kept side-by-side in a tree; you use the left and right arrow keys to compare takes, and a take is only removed if you press D.
Which AI models can I use with 1667?
1667 supports multiple AI models, and you use your own API key and endpoint to connect to them.
Does 1667 require an account or collect any data?
No, there is no account, analytics, or telemetry, and all project files stay on your local disk.
What operating systems does 1667 support and how do I install it?
1667 runs on macOS, Linux, and Windows, and can be installed using a curl or PowerShell command, npm, or by building from source with git.
