Typesetting books with AI

AI doesn't typeset a book by itself, and it doesn't need to. In Ariach it has one job: to understand what you asked for in plain language, and to carry it out in the book. The pages themselves are arranged by a fixed typesetting engine, which gives the same result every time.

In short

The Assistant
Understands a request in plain language, and carries it out in the book's settings and text.
The engine
Arranges the pages by fixed rules. The same book, the same pages, every time.
You
Approve every sweeping change to the text, and undo with a click anything you didn't want.
Assistant
What should I do in the book?

What you can ask the Assistant

In typesetting software, most of the time goes on searching: where do you set this, and what is the setting called? Ariach's Assistant shortens the way. You say what you want, and it knows where that is set. Six areas, each with an example request:

Design
“I want two columns, with no line in the middle,” or “Give me a few design options.” The settings change throughout the book, and you see what they were and what they became.
Headings and styles
“Make the small headings smaller, and not bold,” or “Make every line that starts with פרק a heading.”
Text
“Remove all the bold in the text,” or “Replace every וכו׳ with וכולי.” The places are shown for your approval before anything changes.
Otzaria
“Bring Maseches Niddah from daf 15 to daf 20, with Rashi and Tosafos.” The sefer is built with its commentaries, each note in its place.
Pages
“Fix the pages flagged for review.” It applies the fixes the engine suggests, and whatever is still open stays flagged, with an explanation.
Title page
Select the title-page lines at the top of the file, and the Assistant suggests how to divide them into fields: what goes on the title page, what goes on the back of the title page, and what stays as text. Correct it, and create it all in one step.

Who arranges the pages: an engine, not a guess

This is the most important distinction on this page. The AI in Ariach doesn't decide how many lines go on a page, or where a note will stand. That is done by a typesetting engine: software that measures every letter, calculates the whole book at once, and gives exactly the same pages every time the text and the settings are the same.

For a printed book, that is critical. What you saw on the screen is what will be printed, and what you approved yesterday won't change by itself today. And when a page doesn't work out, the engine says why, instead of hiding the problem.

Three rules the Assistant works by

A sefer is no place for experiments. The Assistant was built so that you see everything it does in the book:

  • It shows you before it changes the text. Before a sweeping change to the text it shows the places that will change, and waits for your approval. A design change goes in at once, with a list of what changed.
  • It asks when something is unclear. A request that can be read more than one way gets a question back, with options to choose from.
  • Every answer can be undone. Beside each of its answers there is “Undo”, and the book goes back to how it was before it.

Who it suits

For someone typesetting a first sefer, the Assistant is the difference between a week of learning and starting right away: you don't need to know what a “running head” is to ask for the chapter's name at the top of the page. For a professional typesetter it is a shortcut for repetitive work, and full manual control stays in the settings panel.

Frequently asked questions

Have a question? We're glad to help.

About your book, a problem or an idea. We usually answer within a business day.

Is there book typesetting software with AI?

Yes. Ariach, typesetting software for seforim that works in the browser, has an Assistant: you tell it in plain language what to change in the book, in the design, the headings, the text or pages that didn't work out, and it does it. The page layout itself is done by a fixed typesetting engine, not by the AI.

Can AI typeset a whole book by itself?

Not to print standard. A language model doesn't count lines or measure the width of a letter, so it can't guarantee that a note will stand on the page of its word, or that two columns will end on the same line. What it does well is understand a request and use the right tool. That is why in Ariach the Assistant operates, and the engine typesets.

What is the difference between automatic typesetting and AI typesetting?

Automatic typesetting is an engine that divides the text into pages by fixed rules: the same text and the same settings always give the same pages. AI understands language. Ariach has both, each in its own role.

Can the Assistant make mistakes?

Yes, like any assistant. So before a sweeping change to the text it shows the places that will change and waits for your approval, after a design change it shows what the setting was and what it became, and every answer it gives can be undone with a click.

Do I need to phrase requests in a special way?

No. Write the way you would talk to a typesetter: “I want two columns,” and then “No line in the middle, and a wider gap.” You can carry on briefly: “Even smaller.”

Can I typeset in Ariach without the Assistant?

Yes. Everything the Assistant does can be done by hand, in the settings panel and in the editor. The Assistant is a shortcut for anyone who doesn't want to hunt for where each setting is.

Who can use the Assistant, and how much?

Anyone who has opened an account and verified their email address. In the sample book, without an account, the Assistant isn't active. During the beta, the Assistant has a weekly usage quota for each account, so that there is enough for everyone. The Assistant panel shows how much of it you have used and how much is left; when it runs out, the rest of the studio keeps working as usual, and what you used frees up again after a week.
