Write with an editor at your side
Composez is an AI writing partner that understands your story’s structure and context, helpeing you draft, revise, and polish your manuscript.
Everything you need to write a novel while leveraging the full power of an AI assistant
Not just another chat window. Composez gives you structured, context-aware AI that works at every level of your manuscript.
Narrative Structure
Organize your manuscript into acts, chapters, and scenes. Each scene has its own prose and summary files. The AI always knows where it is in your story.
Smart Context
Auto-context pulls in relevant scenes, summaries, and reference material before every AI call. The AI maintains consistency across your entire book.
Reference Database
Character sheets, locations, world-building notes — keep them in a structured database that the AI reads automatically. No more repeating yourself.
Multiple Writing Modes
Direct editing, two-phase compose mode, and autonomous agent mode. Get a quick draft, plan then execute, or let the AI handle a multi-step writing session.
Prose Linting
Built-in style checking catches passive voice, clichés, AI-tells, and weak prose. Tuned for fiction — no false positives on invented names or literary style.
Import & Export
Bring in your existing manuscript from Novelcrafter or Markdown. Export finished work to EPUB, DOCX, or Markdown with proper formatting and chapter breaks.
Full Version Control
Every edit is tracked with Git. Review diffs, roll back changes, branch your manuscript. Auto-commits keep a clean history without interrupting your flow.
Any AI Model
Bring your own keys to use any LLM provider. Our GitHub & Claude Code intergration also work seamlessly side-by-side.
Console-First Interface
Power users love the terminal-based workflow. Slash commands, keyboard-driven navigation, and a distraction-free writing environment that stays out of your way.
How it works
From blank page to finished manuscript in three steps.
1
Structure your story
Create your narrative hierarchy — acts, chapters, and scenes. Add character sheets and world-building notes to the reference database.
2
Write with AI
Use slash commands to draft scenes, get feedback, and revise. The AI pulls in relevant context automatically so every response stays consistent with your story.
3
Polish and export
Lint your prose for style issues, summarize scenes for continuity tracking, and export your finished manuscript to EPUB, DOCX, or Markdown.

Novelists
Manage a full-length novel with acts, chapters, and scenes. Keep your world-building and character details consistent across hundreds of pages.
Writing teams
Git-based version control means multiple collaborators can work on different parts of the manuscript, review each other’s changes, and merge cleanly.
