Write with an editor at your side
Composez is an AI writing partner that understands your story’s structure and context, helping you draft, revise, and polish your manuscript.
Don’t write faster, write better.
This is an IDE for writers who care about their craft.
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.
Reference Database
Character sheets, locations, world-building notes — keep them in a structured database that the AI reads automatically. No more repeating yourself.
Claude Code Integration
Pair with Claude Code for powerful multi-agent orchestration and editing. Claude works autonomously on your GitHub-synced novel — drafting chapters, checking continuity, restructuring — while you keep writing.
Smart Context
Auto-context pulls in relevant scenes, summaries, and reference material before every AI call. The AI maintains consistency across your entire book.
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.
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
Based on Aider, the popular open-source AI coding tool. 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.
