A writing app that just writes

Write chapter by chapter

The book editor is built for long manuscripts: organize your book into chapters, track your word count as you go, and save a revision checkpoint whenever you hit a milestone you want to come back to. A checkpoint means a big structural change or a rewritten chapter is never a decision you have to make without a way back.

Chapters keep a long manuscript organized the way a single scrolling document cannot. Moving between chapters, checking the word count for one against the whole, and seeing progress build up over weeks of writing are all part of the same view, rather than something you have to reconstruct from file names or folders.

Writing sprints and internal planning notes live in the same editor, so a timed writing session or a note about where the plot needs to go does not mean switching to a separate app, a separate document, or a sticky note you will lose track of later.

Collaborate without losing control

You can invite collaborators with either read-only or edit access, depending on how much control you want to hand over. An editor who needs to make direct changes gets edit access; a beta reader who should only comment gets read-only, so you decide who can change the manuscript itself and who can only respond to it.

Comments and suggestions are threaded and land right in the chapter they refer to, instead of arriving in a separate email or a comment thread you have to match back to the manuscript by hand. A note about a specific paragraph stays attached to that paragraph.

That threading is what keeps a manuscript with several collaborators readable instead of scattered. A dozen notes from an editor and two beta readers, each tied to the exact chapter and passage they are about, are easier to work through than the same dozen notes spread across separate emails with no context attached.

From manuscript to finished file

When the manuscript is ready, the formatter turns it into an ebook and a print-ready PDF, so you are not exporting into a separate formatting tool to get a file you can actually publish or send to print. Writing and formatting stay in the same place, so a chapter finished in the editor moves toward a finished book without a separate conversion step outside it.

That is the difference between an editor built only for drafting and one built for the whole trip from a blank chapter to a file a reader can actually open. The manuscript you have been tracking chapter by chapter, checkpoint by checkpoint, is the same one the formatter turns into an ebook and a print-ready PDF at the end, with the same chapters and the same word count you watched grow while writing it.

No AI. Ever.

No AI. Ever. Your manuscript is never used to train a language model or fed to one at any point while you are writing, editing, or formatting it in Cabins Press. For an author who wants to control who and what sees an unpublished manuscript, that promise applies for as long as the book stays in the editor, through every draft, revision checkpoint, and collaborator invited to read it.

• Chapters, word count, and revision checkpoints
• Writing sprints and internal planning notes
• Collaborators with read-only or edit access
• Threaded comments and suggestions in the chapter they belong to
• A formatter that produces an ebook and a print-ready PDF
