What is it?

Manga Generator is a workflow tool for producing manga from source text such as a novel. Working with Codex, it moves through script writing, name (storyboard) drafts, image generation, text placement, quality checks, and PDF output.

Dialogue and speech balloons are placed separately from the artwork, so lines can be revised later without regenerating the images. The README describes a setup flow in which Codex installs required tools such as Node.js, a browser, Japanese fonts, Python with PDF libraries, and Poppler, and then runs a check command.

Image generation, visual review of generated pages, and sub-agent review depend on the Codex environment having those capabilities available. The project is written in JavaScript and released under the MIT License. Claude Code and ComfyUI setups are also documented as alternatives.

Key features

  • 01Splits a source text into script, storyboard, and page stages.
  • 02Generates character reference images and panel images.
  • 03Places text and speech balloons separately from artwork for easy edits.
  • 04Checks generated images and runs review steps before export.
  • 05Exports finished pages as PDF and includes a reproducible package.

Use cases

  • Adapting a web novel or short story into a manga draft.
  • Producing a multi-page comic from a text script with consistent characters.
  • Iterating on dialogue wording without regenerating artwork.

Quick start

Things to know

  • Full automatic production requires a Codex environment with image generation, visual image checks, and subagent review.
  • The Claude Code path needs a separately prepared GPU environment for ComfyUI.
  • Image generation depends on external tools and may run into usage quota limits.
