Typesetting software for seforim: Ariach, Tag, InDesign or Word

No one program is right for every book. Tag is the long-standing tool of professional typesetters, InDesign is strong in graphic design, and Word is enough for a simple book. Ariach is new typesetting software that works in the browser: no installation, no codes, with commentaries around the text and proofreading built in.

In short

Ariach
In the browser, with no installation and no codes. From a Word file to Tzuras HaDaf, the classic Vilna page layout, with proofreading and a print PDF. Free during the beta.
Tag
The oldest and deepest for seforim. You work in it with codes, and it takes learning and a license.
InDesign
The best for graphic design and images. Not built for commentaries around the text.
Word
Enough for a kuntres and a simple book, and it has add-ons for Torah typesetting. Breaks down with long notes and complex layouts.

The four programs, side by side

The table compares what matters to someone publishing a sefer: who the software was built for, how you work in it, what it can do with commentaries, and what you pay for it.

What Ariach can do

Ariach was built for anyone who wants a Torah book typeset to a print-shop standard without first learning typesetting software. This is what it does today:

Tzuras HaDaf and any multi-text sefer
The main text in the middle and the commentaries around it, with the lines of commentary above the Gemara, a narrow column in the margin, commentary on a commentary, and sides that switch between right-hand and left-hand pages. Choose a ready-made layout, or build one on a drawing of the page.
Full pages, and a page that explains itself
Pages and columns end on the same line throughout the book. A page that couldn't be set within the limits you gave is flagged, with the reason and what you can do about it.
What you set by hand doesn't break
“New page here” or “Keep with the next paragraph” is anchored to words, not to a place on the page. The text changes, and the instruction stays where it was.
Hebrew typography
Nikud and taamim, Rashi script, a styled first word set in a window, catchwords, numbering in Hebrew letters or by daf and amud, and precise limits for justifying lines.
Proofreading inside the software
Checks for spelling, punctuation and gershayim, rules of your own, and a check of source references and quotations against the Otzaria library. Search and replace that understands nikud, full and short spellings, and prefixed letters.
From Word and Otzaria, and back
A Word file is built into a book with its notes and headings, a commentary from a separate file is placed by its dibbur hamaschil, and a whole sefer comes from Otzaria with its commentaries. You can export the book back to Word, EPUB and Otzaria.
A PDF for print
Black only or four colors, bleed, crop marks and registration marks. The PDF is identical to the pages on the screen. The version sent to print is kept, and its PDF can be downloaded again. To go on working in InDesign there is also an IDML export, as a trial.
An Assistant that does the work
Write what to change, in the design, the headings, the text or the pages, and it does it. A sweeping change to the text is shown for your approval first.

What a multi-text sefer typeset in Ariach looks like, with an explanation of the layout: typesetting in Tzuras HaDaf. And what you can ask the Assistant: typesetting with AI.

When Tag is the right choice

Tag is the long-established typesetting software of the Torah book world, and many typesetters have worked in it for years. It was built from the start for seforim, for multi-text layouts, nikud and taamim, and an experienced typesetter can get any layout they can think of out of it.

The price of that power is the learning. Work in Tag is done with codes written inside the text, and the interface is unlike any other software. Someone who has mastered it, with scripts and templates of their own, has no reason to leave it for one book. Someone just starting out should count on a course and a period of getting used to it before the first page.

When InDesign is the right choice

InDesign is the software of graphic designers and publishers all over the world. For a book where the design is the main thing, such as an album, a book with many images, an illustrated Haggadah or a cover, it has no rival.

For an ordinary Torah book, with text and notes, it works well in the hands of someone who knows it. The difficulty starts with commentaries around the text: it wasn't built to arrange several texts that depend on each other on the same page, and every correction to the text sends the typesetter back to work by hand.

When Word is enough, and what the add-ons give you

For a short kuntres, a source sheet or a simple book without long notes, Word is enough. Its advantage is obvious: it is already installed, and you already know how to work in it.

In recent years Word has gained add-ons for Torah typesetting, such as וורד תורני, תוסף צורת הדף, עמודה and רב טקסט לוורד. Some of them are free, and some also arrange commentaries around the text. If you want to stay in Word, they are a good way forward. They work inside Word, and so within the limits of its layout engine too.

What exactly breaks as the book grows, and how to carry on from the same file: typesetting a sefer from Word.

When Ariach is the right choice

Ariach is a particularly good fit when:

  • The text is already written in Word, and you want to get from it to a book without retyping or re-marking it.
  • The book has notes or commentaries, and every proofreading correction moves pages.
  • Several people work on the book, and the proofreader needs to comment in the book itself.
  • You don't have a computer you can install software on, or you work through a filter. Ariach opens in the browser, and it was built to work through NetFree too.

And when it isn't: when the book is full of images inside the text and tables. Those don't exist in Ariach yet.

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.

What is the best typesetting software for seforim?

It depends on the sefer and on who is typesetting it. A sefer with commentaries around the text needs software built for multi-text layouts: Tag, or Ariach. For a book with many images and graphic design, InDesign. For a simple kuntres without long notes, Word can be enough, especially with an add-on for Torah typesetting. If you are typesetting your first sefer and want to start today, with nothing to install and no course, you can open Ariach's sample book.

Is there free typesetting software for seforim?

Ariach is in beta, and is free to use during this period. We'll announce any charge in advance. Tag and InDesign are paid software, and Word requires an Office license or subscription. Some of the add-ons for Torah typesetting in Word are free.

Does Ariach replace Tag?

Not in everything. Tag is long-established software that professional typesetters have worked in for years, with codes and scripts they have built up. Ariach is young, and it doesn't yet have images inside the text or tables. Its advantage lies elsewhere: you work in the browser, you see the pages as you type, a page that didn't work out explains why, several people work on the same book, and there are no codes to learn.

Can I move a book I started in other software to Ariach?

If you have the text as a Word file (.docx), upload it and it is built into a book, with its notes and headings. Design done in other software doesn't carry over, and you set it again in Ariach. Tag and InDesign files can't be read.

I'm a professional typesetter. Why try new software?

Because of what happens after proofreading. In Ariach the whole book is laid out again after every correction, and what you set by hand is anchored to words, not to a place on the page, so it doesn't move when the text changes. The proofreader comments and suggests corrections in the book itself, without files going back and forth.
