Everything you need to write, collaborate, and publish professional books — powered by AI with full transparency.
Most writing tools treat your 80,000-word manuscript like a single document. BookOS gives you a hierarchical editor with parts, chapters, sections, and paragraph-level control — so you can write, rearrange, and manage complexity at any scale.
BookOS gives you a suite of AI writing tools that understand your voice, your characters, and your story. Every AI suggestion is transparent, traceable, and under your complete control.
Other AI tools invent facts, fabricate quotes, and create characters that don't exist in your story. BookOS's Anti-Hallucination Engine ensures every AI suggestion is sourced from your actual manuscript content.
Before you submit to publishers or self-publish, run BookOS's Originality Detection to get your Safe Publishing Score™ — a comprehensive analysis ensuring your manuscript is original and publication-ready.
Invite editors, co-authors, and beta readers into your manuscript. See who's working where in real time, leave contextual comments, and resolve suggestions without losing a single word.
In the age of AI-assisted writing, publishers and readers want transparency. BookOS's Authorship Audit Trail tracks every contribution — human and AI — so you can prove your work's provenance with confidence.
The hardest part of writing a book isn't talent — it's consistency. BookOS's writing goals and streak system turns your daily practice into a visible, motivating habit that keeps you on track.
BookOS's Export Suite produces publisher-quality DOCX, PDF, EPUB, and Kindle-ready files with professional typography, front/back matter, and customizable formatting — no external tools needed.

Share your manuscript with beta readers through a secure, purpose-built portal. Control which chapters they see, collect structured feedback, and manage responses — all without giving up control of your work.
BookOS's Chapter Kanban board gives you a visual overview of every chapter's status. Drag chapters through 5 workflow stages — from idea to final draft — and always know exactly where your book stands.
