1667 asks a model for the next paragraph, then keeps every take it gives you side by side on a tree you can walk back through. Your keys, your endpoint, your files on your disk. No analytics, no telemetry, no account anywhere in the source.

Upstairs, one of the five lanterns went dark without spending its oil.
» summarize the story so far
Maren keeps the last lit lantern-house on the Sorrow Cliff road. A
three-day storm has closed the pass; the inn below is full of stranded
travelers. One guest, calling himself Ashe, paid for oil he never burns
and carries a compass that points at want, not north.

×2 Maren counted the lanterns twice before answering. Four lit, one dark,
and the dark one was the traveler's — though he had paid for oil like
everyone else, and paid in coin so old the mint had no name for it.
'You'll want the corner room,' she said. 'It keeps its heat, and it
keeps its opinions to itself.'

What it is
It drafts. You decide what stays.
You move through a manuscript, and the model writes a paragraph when you ask it to. Then it stops and waits for you.
Ask again, keep both
Ask for another version of a paragraph and the one you were reading stays where it is. The new take sits beside it, and ← and → flip between them. Every take you generate stays on the tree, and d is the only thing that removes one.
The shape is a tree
A story is a tree of parts and takes. The story line is the path you have selected through it. Branches you walked away from are still there, and still yours to come back to.
It lives in a folder
Stories sit in a directory you chose. Export writes Markdown next to them. There is no server to sign in to and nothing to migrate off later.
The tree
Every draft you didn't keep, still there.
Ask for another take and the one you were reading does not go anywhere. It becomes a sibling. Press m and the shape of the whole thing opens up: the line you are on, the forks you made, and the paragraphs you wrote once and walked away from.
Three views, cycled with the same key. Nothing is archived, nothing is pruned on your behalf, and d is the only thing that removes a take.
- path
- The story line as it reads now. One row per part, sibling takes as rings beside it, word counts down the right.
- tree
- Every fork you have made, with the quiet runs between them collapsed. Cold branches fold away, and l opens the one you pick.
- mass
- The same story by weight. Lines you kept writing, set against the ones you abandoned after a paragraph.

Your keys. Your prose style. Your machine.
1667 includes no model and rents you nothing. Point it at a provider you already pay, or at a model running on your own computer. The request goes straight there.

Left out on purpose.
Each of these was considered and turned down.
No telemetry
No analytics, no crash reporter, no install id. There is no such code.
No cloud
No sync, no server of ours. Stories never leave the folder they are in.
No ghost autocomplete
Nothing is generated until you press a key that asks for it.
No chat sidebar
Type an instruction, get a paragraph. There is no thread to scroll back.
FAQ
Questions worth answering plainly.
Does it write the book for me?
No. It writes a paragraph when you ask for one, in the direction you gave it, and then it stops and waits. You choose the take, you cut the line, you decide what the chapter is. The judgement stays yours.
What happens to the takes I don't use?
They stay. Every take is written to the tree the moment it exists, and moving to another one changes nothing about it. The map shows you all of them, including the lines you abandoned after a single paragraph. Only d removes a take.
Is anything collected about me?
No. There is no analytics code, no telemetry, no crash reporter and no install id in the source. Every request the program makes goes to the endpoint you configured, with one exception: an optional update check, which ships off. Turned on, it reads a version number and tells you. It downloads nothing.
Why 1667?
1,667 words a day for thirty days is fifty thousand, which is the pace that finishes a first draft. The number names that pace. Nothing in the program tracks whether you hit it.
Where does my writing live?
In a folder you chose. Run 1667 init in ~/book and that is your project. Export writes the selected story line to Markdown in the same place. Back it up like any other directory. There is no export step to be trapped behind.
Which models can I use?
Anything behind an OpenAI or Anthropic compatible endpoint. Presets ship for OpenAI, Anthropic, OpenRouter, Ollama, LM Studio, llama.cpp, KoboldCpp, and a custom endpoint. Keys are stored in a private file on your machine and sent only to the provider they belong to. A model running locally needs no key at all.
Do I need to be good at the terminal?
You need to be able to open one. After that it is arrow keys to move, space to continue, and ? for the rest. There is no shell scripting and no configuration file to hand-edit. Settings are a panel behind the comma key.
What does it cost?
Nothing. It is Apache-2.0 source with no paid tier, because there is no server to pay for. You pay whatever your model provider charges, directly to them, or nothing at all if you run a model locally.
1,667 words. Tonight.
Open a folder, run it, and write the next paragraph.
