Transform Your
Manuscript|
ChapterWise transforms manuscripts into structured, analyzable content with AI-powered literary insights. From character arcs to narrative structure, see your writing with new clarity.
Open Source Ecosystem
Fully open source
The VS Code extension and Claude Code skills are free and open source. The Codex format is openly licensed, non-proprietary, and built on blockchain data hygiene standard formats. ChapterWise adapts to VS Code, Cursor, or Claude Code, so you can bring your own compute. Manage your projects natively on GitHub.
VS Code Extension
Syntax highlighting, real-time validation, tree navigation, and powerful commands for Codex files. Works with VS Code and Cursor.
Codex Format
A human-readable YAML specification for structured narratives. Recursive hierarchy, world-building, cross-media support, and version control with Git.

Claude Skills
AI-powered skills for Claude Code. Convert, format, explode, implode, and manage Codex projects with Git integration and tools built for writers.
Git Native
ChapterWise is built on Git from the ground up. Your manuscripts, story bibles, scripts, and codexes live in standard Git repositories. Version every draft, branch for rewrites, and collaborate with pull requests. ChapterWise keeps a synced cache of your repo so you can share your work beautifully. Everything is private by default, with options to create private share keys and control exactly how and with whom you share. Plain text formats mean clean diffs, no lock-in, and full ownership of your creative work.
Born from a love of the craft of writing, and a refusal to let AI replace it. ChapterWise takes the drudgery out of managing large bodies of work. Search through hundreds of pages, reorder chapters, keep track of what goes where. AI helps your writing fall into place. Insert, search, restructure, transform. Your prose stays yours.
Written by you. Transformed by ChapterWise.
