Scriptorium's opening screen, offering to choose a project folder, with a list of recent projects below it.
The first screen. Point it at any folder and it becomes a project.

Getting started

1

Point it at a folder

An empty one, or one that already holds a book. Scriptorium adds whatever structure is missing and never touches a file that already exists — your manuscript is safe from the first click.

2

Let it read

It indexes every Markdown file it finds. A million words takes about a second, and it tells you what it is doing while it works.

3

Write, search, build

All of that works immediately, with no model and no licence. Type help in the chat at any point and it will tell you what it can do — answered by the app itself, not by a language model.

4

Add the collaborator when you want it

Pro downloads a language model that runs on your own machine. If your laptop is not built for that, it connects to Ollama, or to your own OpenAI or Anthropic account instead.

What it needs

For the free version

Windows 10 or 11. Anything that runs a browser comfortably will run this. Writing, searching, building books and the publish checklist ask nothing unusual of your machine.

Book building uses Pandoc and XeLaTeX, which the app will point you at if they are missing.

For the Pro collaborator

To run the model on your own machine, a reasonably modern graphics card — roughly 8 GB of video memory. That keeps your book entirely on your computer.

Most writing laptops do not have that, and there is no reason a novelist should have to buy a gaming machine. So the collaborator also works through your own OpenAI or Anthropic account, on any laptop or tablet that runs Windows. You choose which in Settings, and your key is encrypted on your machine.

Your book stays yours

No account and no telemetry. Your manuscript stays on your machine unless you choose to use a cloud service, and your files stay as plain Markdown you can open with anything.
