Rejected proof
In a tool built for English, right-to-left text comes apart. Then every small fix goes back to a designer, and waits.

AI assistant (MCP)
Connect Claude, Codex or another MCP app to Oktob on your Mac. It is optional: Oktob works fully without it.
Your AI app sends what it reads to its own provider. Your book and its files stay on your Mac.
Why Oktob exists
Al-Mutanabbi · paired verse · coloured tashkil
We built Oktob because we know what it is like to watch software break your language. Arabic asks the most of a typesetter: joined letters, vowel marks, two directions in one line. We made it work first, then made sure the other direction works as well.
We started Oktob after watching our own Arabic pages come back from software with the letters broken apart and the question marks on the wrong side.
The plan
Your files stay on your Mac. Snapshots and recovery copies keep your work safe.
The whole story
Oktob is a Mac app for authors who want to make their own book. You write or import your manuscript, organise it into parts and chapters, choose a book design, check every page in Proof, and export a print PDF and an EPUB. It sets right-to-left and left-to-right text correctly, today in Arabic and English, alone or together in one book. It began with Arabic, the hardest case, and more languages are planned.
Join the waitlist. We write when there is something you can try. Nothing else.
